Week 8 - Sex and Marriage

Week 8 — “Sex and Marriage”

In Week 8 of our eight-week series through The Meaning of Marriage, Simon and James conclude the series by exploring one of the most personal, misunderstood, and emotionally charged subjects in modern life: sex.

Why does modern culture often treat sex as either casual appetite or personal identity? Why do some Christians still carry shame, fear, or confusion about sexuality? And why does the Bible place such strong boundaries around something it also celebrates as good?

In this episode, we unpack Timothy Keller and Kathy Keller’s argument that the biblical view of sex is neither prudish nor permissive. Scripture does not treat sex as dirty, nor does it treat it as casual self-expression. Instead, sex is presented as a God-created sign and seal of covenant union — a powerful act of whole-life self-giving designed to unite, deepen, renew, and embody marital love.

Together, we discuss Genesis and the meaning of “one flesh,” why sex is more than physical appetite, how sexual union creates profound personal attachment, and why covenant commitment matters. We also explore singleness, chastity, temptation, shame, grace, pornography, emotional intimacy, desire differences in marriage, performance anxiety, healing, communication, and the role of sexual intimacy in sustaining covenant love over time.

Most importantly, we look at Christ — the true Bridegroom who fulfills the deepest ache beneath human longing. Sex is not ultimate. Marriage is not ultimate. Both point beyond themselves to the joy, union, intimacy, delight, and security believers will one day experience fully in Christ.

This conversation is not just for married couples. It is for singles, dating couples, engaged couples, skeptics, people carrying sexual shame, couples struggling in intimacy, and anyone trying to understand the body, desire, covenant love, temptation, healing, and the deeper meaning of sexuality in the Christian life.

Series Reflection:
As this eight-week journey comes to a close, Simon and James reflect on the major themes of the series — covenant love, grace, sacrifice, truth, friendship, singleness, difference, sexuality, and the gospel itself. Throughout every chapter, the deeper message has remained the same: marriage only makes sense through Christ, and every human longing ultimately points beyond itself to Him.

Chapter 1

Week 8 - Sex and Marriage

Simon

Welcome to Walking the Way. This is a podcast about learning how to live the Christian life—carefully, honestly, and over time. Not just what Christians believe, but how those beliefs shape a well-lived life. I’m Simon, and each week I’m joined by James Porter—theologian and teacher—as we walk through biblically grounded books and themes that aim to form our thinking, our habits, and our character. Because the Christian life is not just about belief, but how that belief is meant to be lived, and over time, produces a grounded and meaningful life.

James Porter

Thanks for having me, Simon.

Simon

Yeah — I’m glad you’re here. Today we’re finishing our eight-week journey through The Meaning of Marriage by Timothy Keller, written with Kathy Keller. This is Week 8, and the chapter is called Sex and Marriage. And because this is the final week, this chapter has a unique place in the series. It is not just an extra topic added at the end. It brings together almost everything we have talked about. The gospel. Covenant. One-flesh union. The body. Commitment. Self-giving love. Singleness. Marriage. Desire. Identity. Community. And the final hope of union with Christ. So we need to talk about sex carefully. Not awkwardly. Not casually. Not harshly. Not as if sex is dirty. Not as if sex is merely appetite. Not as if sex is private self-expression with no meaning beyond personal choice. And not as if the Bible’s sexual ethic is just a random list of restrictions. Keller’s argument in this chapter is that the Bible puts boundaries around sex because sex is so powerful, so good, so meaningful, and so deeply connected to whole-life self-giving.

James Porter

Yes. And that is a very different starting point than many people assume.

Simon

Exactly. A lot of people assume Christianity has a low view of sex. They assume the Bible restricts sex because it is suspicious of the body, suspicious of pleasure, suspicious of desire. But Keller says the opposite. The Bible has a high view of sex. It is high enough to celebrate sex within marriage. High enough to connect sex to covenant. High enough to say sex is not just physical. High enough to say sex involves the whole person. High enough to say it points beyond itself to the joy of God and the future union we will have with Christ. And because the Bible has such a high view, it refuses to treat sex as casual. That is important. The Bible’s boundaries are not there because sex is insignificant. They are there because sex is too significant to be detached from covenant.

James Porter

That changes the emotional tone of the whole discussion.

Simon

It does. Because if you think God’s sexual ethic is mainly about shame, then the whole subject feels heavy and humiliating. But if you understand that God created sexuality as a good gift, then the question becomes: What is sex for? What does it say? What does it do? Why does Scripture connect it to marriage? And how do Christians live faithfully with desire — whether single or married — without denying desire, worshiping desire, or being ruled by desire? That is where Keller takes us. And we also need to say something pastorally at the beginning. This subject is tender. People bring different stories into it. Some bring regret. Some bring shame. Some bring confusion. Some bring sexual frustration in marriage. Some bring painful histories. Some bring wounds from being used, pressured, betrayed, abused, or treated like an object. Some bring the ache of singleness and desire. Some bring disappointment that sex in marriage has not been what they expected. So this episode is not meant to crush people. It is meant to tell the truth in a way that leads toward grace, wisdom, repentance, healing, and hope.

James Porter

Yes. And we should also be clear that biblical teaching on sex never justifies coercion, pressure, manipulation, abuse, or disregard for another person’s dignity.

Simon

Absolutely. When Keller talks about sex as self-giving, that is not a license for one spouse to demand, use, or pressure the other. Self-giving love cannot be forced. Christian marriage is always under the cross. So as we talk about sex in marriage, we are talking about mutuality, tenderness, patience, safety, honesty, and love. Not selfish entitlement. Not control. Not performance. Not shame. So James, before we move further, when this chapter talks about sex and marriage, what is it really trying to show us?

Chapter 2

Summary Section

James Porter

Yeah… this chapter is trying to show that sex is a God-created sign and seal of whole-life covenant union. That is the center of the chapter. Keller says there are really two levels to the question. First, at the foundational level, we need to understand the basic principle of the biblical sex ethic. Why does God confine sexual activity to marriage? Second, once we understand that reasoning, we need to ask how Christians live in line with it practically — whether single or married.

Simon

So the chapter is not just saying, “Here is the rule.”

James Porter

Right. It is asking, “What is the rule for?” And Keller begins by showing that there are several common views of sex. One view says sex is just a natural appetite. Like food. If you feel the need, satisfy it. Variety is normal. Restriction is unhealthy. Another view says sex is dirty or degrading. It belongs to the lower physical part of us, not the higher spiritual part. It may be necessary for reproduction, but it is still embarrassing or shameful. A third view says sex is mainly self-expression. It is a way to be yourself, find yourself, fulfill yourself, define yourself. And in that view, marriage may be one way to use sex, but it is not essential. The individual decides what sex means.

Simon

And Keller says the biblical view is different from all three.

James Porter

Exactly. The Bible does not say sex is merely appetite. It does not say sex is dirty. And it does not say sex is simply private self-expression. It says sex is good, embodied, joyful, powerful, covenantal, and deeply personal. Sex involves the body, but not only the body. It affects the heart. It binds. It discloses. It gives. It says something. And because sex is designed for whole-life self-giving, it belongs in the place where whole-life self-giving has actually happened — the covenant of marriage.

Simon

So the basic Christian sex ethic is not rooted in body hatred.

James Porter

No. Keller says biblical Christianity is profoundly body-positive. God created the physical world and called it good. The Son of God took on a real human body. The future hope is not escape from the body but resurrection. The Bible celebrates sexual passion in marriage, especially in the Song of Solomon. So if someone says sex itself is bad or dirty, the Bible contradicts that.

Simon

And yet the Bible is strict.

James Porter

Yes. Because a high view of sex requires boundaries. Genesis says a man and woman are joined and become one flesh. That phrase means physical union, but it also means more than physical union. Marriage joins two lives legally, socially, economically, emotionally, personally, and spiritually. The two become a new unit. So sex is the bodily sign and seal of that whole-life union. Sex says, “I give myself to you completely, permanently, and exclusively.” And Keller says we must not use sex to say anything less.

Simon

So sex belongs inside the covenant because it expresses the covenant.

James Porter

Yes. And within marriage, sex also renews the covenant. Like Israel had covenant renewal ceremonies to remember and recommit to the covenant, sex in marriage is a unique way for husband and wife to give themselves again to one another. It is not just a pleasure added to marriage. It is part of maintaining and deepening the one-flesh union.

Simon

Then Keller turns to Paul.

James Porter

Right. In 1 Corinthians 6, Paul warns Christians against sex with a prostitute, and his reasoning is important. He does not say, “That is just a body act.” He says sexual union makes a kind of one-flesh claim. So Paul’s point is that sex is supposed to unite the whole person. It is deeply contradictory to give your body while withholding your life. That is why sex outside covenant is personally damaging. It attaches without security. It awakens marriage-like bonds without marriage-like commitment. It creates deep connection in a context where the other person may have no covenant responsibility.

Simon

That is why Keller calls sex a commitment apparatus.

James Porter

Yes. Sex was designed to help whole-life entrustment happen. Even when used wrongly, it still tends to create deep attachment. So outside marriage, people often experience jealousy, obsessiveness, pain, confusion, and difficulty breaking up. Or they learn to suppress sex’s bonding power in order to keep it casual. And that can make them less able to trust and commit later. So the Bible’s call to chastity is not because sex is low. It is because sex is high.

Simon

Then the chapter becomes very practical for singles.

James Porter

Yes. Keller says single Christians who want to live chastely need several resources. They need the spousal love of Jesus. They need to remember that sexual and romantic longing often carries a deeper longing for union, closure, and fullness that only Christ can finally satisfy. They need Christian community — not just generic social life, but a community where singles are not desperate for marriage, not afraid of marriage, not choosing by money and physical beauty, and not made to feel like extra people in a family-centered church. They need open, honest conversation about the Bible’s view of sex. They need a balanced approach to sexual thoughts and desires — neither shame-filled legalism nor indulgent permissiveness. And they need the gospel when they fail, because grace neither minimizes sin nor leaves people drowning in shame.

Simon

And then Keller gives the Jane Eyre story.

James Porter

Yes. That story shows that in temptation, technique is not enough. You need conviction. Jane is tempted to become Rochester’s mistress. Every part of her inner life seems to argue for giving in — feeling, reason, pity, desire, loneliness, even a sense that no one else would care. But she resists by planting her foot on God’s law. Keller’s point is that temptation is the moment when obedience often does not feel reasonable, fair, or emotionally satisfying. That is exactly when God’s word matters.

Simon

Then Keller turns to married couples.

James Porter

Yes. Because if sex is confined to marriage, then sex in marriage should not be neglected or treated as unimportant. Paul speaks candidly in 1 Corinthians 7 about husbands and wives giving themselves sexually to each other. In a culture where women were often treated as the property of men and men could pursue sexual pleasure elsewhere, Paul’s teaching was revolutionary. He says the husband’s body belongs to his wife, and the wife’s body belongs to her husband. That is mutual. Reciprocal. It rejects the double standard. And it teaches that sexual pleasure and satisfaction in marriage matter for both spouses.

Simon

Then Keller talks about the erotic marriage.

James Porter

Yes. He says each spouse should be more concerned with giving pleasure than getting pleasure. The deepest joy becomes the joy of giving joy. He and Kathy tell honestly about struggles early in their marriage, when sex felt like performance and both felt like failures if things did not go a certain way. They learned to stop obsessing over performance and begin simply loving each other in sex. That changed everything.

Simon

And that has implications for differences in desire.

James Porter

It does. If sex is mainly about getting, then different levels of desire become a battlefield. But if sex is about giving, then the spouse with lower desire can sometimes give as an act of love, and the spouse with higher desire must also give by being patient, tender, attentive, and not demanding. Again, this cannot become coercion. The whole framework is mutual self-giving, not entitlement.

Simon

Then Keller talks about context.

James Porter

Yes. He says many spouses differ over what makes sex emotionally possible or satisfying. One may be ready quickly. The other may need warmth, conversation, emotional preparation, or a sense of closeness. The answer is not mockery or pressure. It is learning. Patience. Communication. The Kellers say it took years to become good at satisfying each other sexually. But the patience paid off.

Simon

Then sex becomes a test.

James Porter

Right. Because sex is such a sensitive sign and seal of the relationship, deeper problems often show up there. Past guilt. Fear. Anger. Mistrust. Disrespect. Unresolved conflict. A lack of sexual compatibility may not simply be about technique. It may reveal deeper relational trouble that needs to be addressed. And because marriage changes over time — children, age, illness, stress, loss, changing bodies — couples must keep adapting. Sex in marriage is like oil in an engine. Without it, relational friction can burn out the motor. So Keller says married couples should never give up working on their sex life.

Simon

And finally, he ends with the glory of sex.

James Porter

Yes. Sex is glorious because it reflects something of the joy of the triune God. Father, Son, and Spirit eternally love, delight in, glorify, and pour joy into one another. Marital sex, rightly understood, is a bodily echo of self-giving love and delight. It also points forward to the ultimate union we will have with Christ and with God’s people in the renewed creation. So sex is not ultimate. Christ is ultimate. But sex is glorious because it points to glory.

Simon

That gives the chapter real shape. So just to summarize, what we’re looking at today is this: Sex is not merely appetite, not dirty, and not private self-expression. It is a God-created sign and seal of whole-life covenant union, designed to express and renew the self-giving love of marriage and to point beyond itself to the final joy of union with Christ.

James Porter

Yes. That’s exactly right.

Simon

And the chapter will walk us through the false views of sex, the biblical view of the body, one-flesh union, sex as covenant renewal, sex as a uniting act, sex as a commitment apparatus, practical chastity for singles, the inner dialogue of temptation, the importance of erotic love in marriage, the need for mutual giving, sex as a test of the relationship, and finally the glory of sex as a signpost to God’s own love and our future joy. So with that in mind… let’s move into the deep dive.

Simon

Alright… Keller begins the chapter by saying we cannot talk about marriage without talking about sex. But he immediately says the subject has two levels. The first level is foundational. Why does the Bible confine sexual activity to marriage? That is the question behind the rule. The second level is practical. Once we understand the biblical reasoning, how do Christians actually live with that teaching? How do single people live chastely without becoming shame-filled or isolated? How do married couples cultivate sexual love without turning it into entitlement, performance, avoidance, or duty without delight?

James Porter

Yes. And that order matters. If you jump straight to the practical commands without understanding the vision, the Bible’s teaching can feel arbitrary. But if you understand what sex is, the commands begin to make sense.

Simon

So Keller first walks through several common views of sex. The first is sex as appetite. This view says sex is like hunger. If you feel the appetite, satisfy it. If variety is available, enjoy variety. If old taboos restricted people, we have matured past those taboos. And in this view, telling people to refrain from sex is like telling them not to eat. It sounds unnatural, unhealthy, and impossible.

James Porter

Right. That view is very common because it feels simple. Sex is a biological drive. Biological drives need expression. Therefore restraint is repression. But Keller says that view is too shallow. Sex is an appetite, but it is not merely an appetite in the same category as food or sleep. And even food and sleep require discipline. No wise person says, “If I want food, I should eat whatever I want, whenever I want, however much I want.” Our appetites can be disordered.

Simon

That is helpful. Because people often say, “It’s natural,” as if natural means harmless.

James Porter

Exactly. Many desires are natural, but that does not mean they are rightly ordered. And Keller says sex affects the heart, not only the body. It reaches into the inward person. So if sin is a disorder of the heart, then sexual desire is deeply affected by sin. The sinful heart wants to use sex selfishly. For validation. For power. For escape. For control. For comfort. For identity. For conquest. For emotional medicine. For self-expression without self-giving. So the Bible gives boundaries to direct sex toward its true purpose.

Simon

So the Bible is not saying desire is bad. It is saying desire needs ordering.

James Porter

Yes. Desire is good, but fallen. Strong, but not sovereign.

Simon

Then Keller identifies the second view: sex is dirty. This one is almost the opposite of sex as appetite. It says sex belongs to the lower physical nature. It is degrading. Maybe necessary for reproduction, but spiritually embarrassing. And many people assume that this is the Christian view.

James Porter

Yes. But Keller says that assumption is completely wrong. Biblical Christianity is not anti-body. God made the material world and called it good. God made human bodies. In the incarnation, the Son of God took a real human body. After the resurrection, Jesus still has a glorified body. And the Christian hope is bodily resurrection, not escape from embodiment. So Christianity does not treat the body as trash or sex as inherently filthy.

Simon

That is so important. Because some Christians, even if they do not say sex is dirty, can talk in ways that make it sound dirty. Especially when teaching young people or singles.

James Porter

Yes. And that does damage. If you train people to think of sex as dirty before marriage, it is hard for them suddenly to receive it as holy and good in marriage. The Bible itself is not prudish. Proverbs celebrates marital desire. Song of Solomon contains bold love poetry. And Paul tells married couples not to neglect sexual relations. So the biblical view is not embarrassed by married sexual pleasure.

Simon

Keller even says the Bible is uncomfortable for the prudish.

James Porter

Yes. Because it is both holy and earthy. It refuses both casualness and disgust.

Simon

Then Keller names the third view: sex as private self-expression. This is probably one of the dominant views today. Sex is how I express who I am. How I discover myself. How I fulfill myself. How I define myself. Marriage may be part of that for some people, but the individual decides. In this view, the main question is, “What do I want, and what feels authentic to me?”

James Porter

Right. And Keller says the Bible disagrees with that too. Not because sex has no joy or fulfillment. It has enormous joy. But sex is not primarily about autonomous self-expression. It is about knowing God and building community. It is about covenant union. And if you use it according to that design, rather than just for personal satisfaction, it leads to deeper joy than self-centered use ever could.

Simon

That phrase “knowing God and building community” may surprise people. How does sex relate to knowing God?

James Porter

Because sex is a created sign. It points beyond itself. It points to the self-giving love of God. It points to the deep union God intends between Christ and His people. It points to covenant faithfulness. It points to the joy of mutual delight. So sex is not ultimate, but it is theological. It teaches something about love, union, vulnerability, and joy.

Simon

So the Bible’s view is: Sex is appetite, but not merely appetite. Sex is physical, but not dirty. Sex is pleasurable, but not merely private self-expression.

James Porter

Exactly.

Simon

Then Keller moves into Genesis 2. This is the first explicit mention of sex in the Bible. A man leaves father and mother, is united to his wife, and the two become one flesh. And Paul quotes this in Ephesians 5. At first glance, “one flesh” sounds like it just means physical sexual union. But Keller says it means more.

James Porter

Yes. He explains that “flesh” in the Bible can refer to the whole person. Not merely the body. So becoming one flesh means two people are joined so profoundly that they become a new single unit. Not one person in the sense that their individuality disappears. But one new covenantal reality. They are united socially, legally, economically, personally, emotionally, and physically.

Simon

And the word “united” carries covenant meaning.

James Porter

Right. It means cleaving. Binding. Attaching oneself through covenant. So marriage is not only an emotional relationship. It is a whole-life covenant union. The spouses give up much of their independence. They donate themselves to one another. Their lives become interwoven at every level.

Simon

So when sex is called one flesh, sex is not creating a little isolated physical moment. It is the physical sign of that total union.

James Porter

Exactly. Sex is both a sign and a means. It symbolizes the union, and it deepens the union. That is why Keller says the Bible’s logic is: Do not unite with someone physically unless you are also willing to unite with that person in every other way. Do not become physically naked and vulnerable with someone unless you have also become vulnerable legally, socially, emotionally, personally, economically, and covenantally.

Simon

That is a radically different view from sex as appetite.

James Porter

Completely. Sex is not less than physical pleasure. But it is much more than physical pleasure. It is body language. It is saying something with your whole self.

Simon

And what does it say?

James Porter

It says, “I am yours.” Not temporarily. Not conditionally. Not partially. But completely, permanently, exclusively. That is why Keller says sex should not be used to say anything less than that.

Simon

That line is the core of the chapter. Sex should not say less than the covenant says.

James Porter

Yes. If the body says, “I give myself to you,” while the life says, “I am keeping my options open,” then the body and the life are speaking different languages.

Simon

Then Keller compares sex in marriage to covenant renewal. In the Old Testament, God’s people would have moments where the covenant was read, remembered, and renewed. Not because they were making a new covenant every time, but because the heart needs to remember and recommit. And Keller says sex functions like that in marriage.

James Porter

Yes. The wedding day is wonderful. The couple makes vows. Their hearts are full. But as time passes, life gets ordinary. Stress comes. Disappointment comes. Children come. Bills come. Illness comes. Conflict comes. Routine comes. So husband and wife need ways to remember and renew the covenant. Sex is one unique way of doing that. It is a bodily recommitment. A way of saying again, “I belong to you. I give myself to you. We are one.”

Simon

So sex is not just permitted inside marriage. It has covenant work to do inside marriage.

James Porter

Yes. That is why Keller says marriage is necessary for sex, but sex is also necessary for the maintenance of marriage. Not necessary in the sense that every couple at every moment has the same physical capacity or frequency. Illness, trauma, age, and other realities can complicate things. But in the general design, sexual union has a real covenant-renewing role.

Simon

Then Keller turns to Paul in 1 Corinthians 6. And this is a very important section because people often think Paul had a low view of sex. But Keller says a closer look shows Paul had a very high view. Paul warns Christians not to have sex with a prostitute. And what is striking is his reason. He says sexual intimacy creates a one-flesh reality. What is Paul getting at?

James Porter

Paul is not saying, “Do not have sex with a prostitute because that is merely physical.” He is saying the opposite. He is saying, “Do you understand how deep sex is?” Sex is a uniting act. It was designed to express whole-person self-disclosure and whole-person self-commitment. So when someone gives their body while withholding their life, there is a rupture. The act says more than the relationship can actually support.

Simon

So if Paul thought sex was just physical, his argument would not work.

James Porter

Exactly. If sex were merely physical, then sex with a prostitute would be only a bodily transaction. But Paul says that is not how sex works. Sex speaks the language of union even when the surrounding relationship denies union. That is why Keller says sex without covenant is like tasting food without swallowing and digesting. It takes part of a larger process and detaches it from the whole.

Simon

That image is powerful. Because it shows that the problem is not that food is bad. Food is good. But tasting without swallowing separates the pleasurable moment from the purpose.

James Porter

Right. And that is Keller’s point about sex. Sex is good. But detached from covenant, it becomes distorted.

Simon

Then Keller uses the phrase “commitment apparatus.” He says sex is designed by God to assist whole-life entrustment. So even when it is misused, it still tends to bond. It still tends to make people feel deeply connected. It still tends to awaken vows in the heart. People say things like, “I will always love you,” even when they have made no covenant.

James Porter

Yes. That is one of the most psychologically perceptive parts of the chapter. Sex often creates marriage-like feelings before there are marriage-like obligations. And that mismatch can be deeply painful. One person feels attached. Feels owed something. Feels like the relationship now has a permanence it does not actually have. But the other person has no legal, social, covenantal responsibility even to keep calling.

Simon

That explains jealousy, obsessiveness, and breakup pain.

James Porter

Yes. And it also explains why people stay in bad relationships. They feel joined. They feel somehow connected. Even if the relationship is unhealthy, the sexual bond makes separation much harder.

Simon

Then Keller says if people repeatedly have sex outside marriage, they may have to train themselves against sex’s bonding power. They have to harden themselves.

James Porter

Right. To keep sex casual, you have to suppress what sex is designed to do. You have to detach your heart from the act. Over time, that can reduce sex’s ability to build trust and commitment later. So sex outside marriage can work backward. Instead of making you more able to give yourself, it can make you less able to trust, less able to bond, less able to commit.

Simon

That is an important point because many people think chastity is psychologically harmful and casual sex is freeing. Keller is saying the opposite may be true.

James Porter

Yes. He is not denying that chastity is difficult. It is difficult. But he is saying the Bible’s command is not arbitrary. It fits the nature of sex.

Simon

That brings us to practical chastity. And I appreciate that Keller does not simply say, “Do the right thing.” He asks: What resources do single Christians need if they are going to live this way in a culture that gives almost no support for it? And the first resource is the spousal love of Jesus. Explain that.

James Porter

Sex is for fully committed covenant relationships because it is a foretaste of final union. The deepest sexual and romantic longing is not only about the other person. It is also pointing to a deeper longing for complete union, complete acceptance, complete joy, and complete homecoming. And that deepest longing can only be fulfilled in Christ.

Simon

So sexual desire can carry a spiritual ache.

James Porter

Yes. Not because sexual desire is bad, but because it is a signpost. In temptation, the heart often believes a lie: If I could have this sexual or romantic experience, I would finally feel whole. Finally feel known. Finally feel desired. Finally feel alive. Finally feel complete. But Keller says sex cannot fill the cosmic emptiness created by our separation from God. Only Christ can do that.

Simon

That connects back to Week 7. Christ is the true spouse. The church is the true family. Marriage is penultimate. And sex is also penultimate.

James Porter

Exactly. If you make sex ultimate, it will disappoint you and dominate you. If you receive it as a sign that points to Christ, it can be put in its proper place.

Simon

Keller says resisting temptation requires speaking truth to your heart. Not just trying to suppress desire. Not just distracting yourself. But telling your heart the truth: This cannot save me. This cannot finally fulfill me. This is not the union my soul ultimately needs. Christ is.

James Porter

Yes. And Keller is not saying we only wait for future joy. He says Christians can experience Christ’s love now. Not only believe in it intellectually, but experience it through prayer, by the Spirit. So chastity needs communion with Christ. Not just willpower.

Simon

That is a big correction. Because if the only message is “don’t,” people will eventually run out of strength.

James Porter

Right. The heart needs a greater love.

Simon

The second resource is Christian community. And this ties directly to Week 7. Keller says singles need community with other singles who are neither too hungry for marriage nor too afraid of it. They need singles who are not choosing partners mainly by physical beauty and money. They need Christian families who do not idolize family or make singles feel unnecessary.

James Porter

Yes. That is a very concrete picture. The Christian sex ethic is much harder to practice alone. People need a culture around them. A community where chastity is not weird because everyone is pursuing holiness. A community where marriage is honored but not idolized. A community where singles are not treated as spare parts. A community where dating can be discussed wisely. A community where people can encourage one another without pretending the struggle is easy.

Simon

Keller says the community also needs open discussion about how the Bible’s perspective on sex plays out in real life. That matters because silence creates loneliness.

James Porter

Yes. If no one talks about sex honestly, singles may feel like they are the only ones struggling. Married people may feel like they are the only ones disappointed. People with sexual histories may feel like they are beyond grace. A healthy Christian community has truthful, wise, appropriately bounded conversations about these things.

Simon

Keller admits many churches do not provide this well. And he challenges readers to help create those conditions. That is strong.

James Porter

It is. He is not letting churches off the hook. But he is also not letting individuals passively wait for the perfect community. He is saying: Build it. Help create it. Be the kind of church where this ethic can be lived.

Simon

The third resource is a balanced approach to sexual thoughts and desires. Some Christians feel stained by any strong sexual thought. Others indulge every fantasy. Keller says the gospel is neither legalism nor lawlessness.

James Porter

Yes. Legalism says every unwanted sexual thought makes you filthy and unacceptable. Lawlessness says desire is sovereign and should be entertained without restraint. The gospel says you are saved by grace, not by sexual purity. But real grace also trains you to obey God out of gratitude. So when sexual thoughts come, do not panic and drown in shame. But also do not invite them in and build a home for them.

Simon

Keller uses the old image often attributed to Martin Luther: You cannot stop birds from flying overhead, but you can stop them from nesting in your hair.

James Porter

Exactly. The appearance of a thought is not the same as cherishing it. Desire may arise. You are responsible for what you do next. Do you dwell on it? Feed it? Use it? Create a fantasy life around it? Or do you acknowledge it, turn from it, and bring your desire before God?

Simon

Then Keller says if we do something sexually wrong, we need the gospel for our conscience. This is so important. Because shame can actually fuel future sin.

James Porter

Yes. Grace neither minimizes sin nor traps us in endless guilt. If you sin sexually, the answer is not to pretend it does not matter. But the answer is also not to whip yourself forever. Bring it into the light. Confess. Receive Christ’s pardon and cleansing. Seek wise help if needed. And understand that unresolved shame can stir up obsessive fantasies. Sometimes people keep returning to sexual sin not because they think too little of sin, but because they have never believed the cleansing of grace deeply enough.

Simon

That is a needed word. Because the Christian message is not: You are ruined. It is: You are more sinful than you want to admit, and more loved in Christ than you dared hope. That has been the whole series.

James Porter

Yes. And it applies here too.

Simon

Then Keller tells the Jane Eyre story. And we should slow down here, because it is one of the most memorable parts of the chapter. Jane has fallen in love with Mr. Rochester. But she discovers that he is already married. His wife is mentally ill and living in the house. Rochester pleads with Jane to live with him anyway. To become his mistress. He is lonely. He is miserable. He loves her. He wants her. And Jane’s own heart is in turmoil. What is Keller showing through that story?

James Porter

He is showing the inner dialogue of temptation. Temptation is not always simple. It can recruit feeling. It can recruit compassion. It can recruit reason. It can recruit loneliness. It can recruit self-pity. It can recruit a sense of justice. Jane can think: He is suffering. I could help him. He loves me. I have suffered too. Who would be hurt? Why should I not finally be loved?

Simon

So it is not just lust. It is a whole inner courtroom arguing for disobedience.

James Porter

Exactly. And Keller points out that movie versions often make it seem like Jane resists because she has strong self-esteem. As if she looks inward, finds dignity, and says, “I deserve better.” But in the novel, the deeper issue is that she plants her foot on God’s law. Not because it feels easy. Not because her heart agrees. Not because it seems fair in the moment. But because the law of God is precisely for moments when body and soul are in mutiny.

Simon

That phrase is powerful. Temptation is when body and soul rise in mutiny.

James Porter

Yes. And Keller says obedience means giving God authority even when you do not agree emotionally. If you only obey God when His commands seem reasonable, convenient, or profitable, that is not really obedience. Obedience means: God’s word has authority over me even when my feelings argue otherwise.

Simon

So for single Christians, or really any Christian facing sexual temptation, the question is not, “Can I make my heart stop wanting this?” Sometimes you cannot. The question is: Where will I plant my foot?

James Porter

Yes. On passing feeling? On private reasoning? On cultural permission? On loneliness? Or on God’s word?

Simon

That is direct, but it is honest. Because temptation often does not feel like a test of doctrine. It feels like a moment of emotional survival.

James Porter

Exactly. And that is why conviction has to be formed before the moment of temptation. You decide what is true while you are sane, so that when desire makes you temporarily irrational, you have somewhere to stand.

Simon

That connects back to Week 3 and the marriage vow. Promises tie us to the mast before the storm. Here, conviction ties us to God’s word before temptation.

James Porter

That is a very good connection.

Simon

Then Keller moves from singles to married couples. And he says, since the Bible confines sex to marriage, we should not be surprised that the Bible also instructs married couples to enjoy sex and to do so regularly. That may surprise people.

James Porter

Yes. Because some people hear the Bible’s restrictions and assume the Bible must be reserved or negative about married sex. But the opposite is true. Proverbs celebrates delight in one’s spouse. Song of Solomon celebrates sexual passion. And Paul in 1 Corinthians 7 speaks very directly about mutual sexual responsibility.

Simon

Paul says the husband should fulfill his marital duty to his wife, and the wife to her husband. And then he says the wife’s body belongs also to the husband, and the husband’s body belongs also to the wife. In our world, people may hear that and focus on individual rights. But Keller says in Paul’s world, that was revolutionary for another reason.

James Porter

Yes. In Roman culture, women were often treated as the possession of men. There was a strong double standard. Men could seek sexual pleasure outside marriage in ways women could not. Marriage was often viewed as a way to produce legitimate heirs, not as a place of mutual erotic satisfaction. So when Paul says the husband’s body belongs also to the wife, he is striking a blow against that double standard.

Simon

So Paul is not saying, “The husband owns the wife.” He is saying the opposite of male entitlement.

James Porter

Exactly. He is saying both spouses belong to one another. Both have obligations to sexual faithfulness. Both have a claim to sexual care. Both are to seek the other’s sexual good. That was astonishingly mutual.

Simon

And this is where we need to say again: This is not coercion. This is not a spouse using Scripture to demand sex. This is not ignoring trauma, exhaustion, illness, pain, fear, or unresolved conflict. It is mutual self-giving.

James Porter

Yes. Paul’s vision only makes sense under the larger Christian ethic of love. The body is given, not seized. Sexual duty in marriage is not permission for selfishness. It is a call to mutual care.

Simon

Keller says Paul is giving a remarkably positive view of sexual satisfaction in marriage. Sex should be frequent and reciprocal. One spouse should not simply deprive the other. But the heart of it is not “How much can I get?” It is “How can I give?”

James Porter

Right. That is the erotic marriage. Each partner should be more concerned with giving pleasure than getting it. The greatest pleasure becomes seeing the other person receive pleasure.

Simon

That takes sex out of the consumer framework.

James Porter

It does. Consumer sex asks: Am I satisfied? Did I get what I wanted? Was it exciting enough for me? Covenant sex asks: How can I give myself? How can I love? How can I delight in your delight? How can we renew our union?

Simon

Then Keller tells honestly about his and Kathy’s early struggles. He says they found old talks they had given and were reminded that early in marriage they sometimes dreaded sex. That is a vulnerable thing to admit.

James Porter

It is. And it is helpful because many couples quietly feel like failures. They assume sex should automatically work. They assume if they love each other, it should be effortless. But Keller says it took them time. They were anxious about performance. If things did not go as expected, both felt like failures. Kathy later said they had to learn that orgasm is good, but it is not the whole meaning of sex. The wonder, safety, awe, and joy of simply being one matters deeply too.

Simon

So they had to stop performing and start loving.

James Porter

Yes. That is the heart of it. They stopped making sex a test of personal success and started asking: What can I give to the other? How can I love the other? How can we be one without fear?

Simon

That is a powerful correction. Because our culture makes sex into performance. Technique. Outcome. Comparison. Excitement. Achievement. And then people bring that into marriage and feel crushed.

James Porter

Yes. And pornography especially intensifies that performance framework. It trains people to think of sex as spectacle, consumption, novelty, and personal gratification. But marital sex is about covenantal giving. It is not less pleasurable. But the pleasure is different. It grows through safety, trust, patience, knowledge, and mutual giving.

Simon

Then Keller applies this to the very common issue of different desire levels. One spouse wants sex more often than the other. That can become one of the most painful areas in marriage. What does Keller say?

James Porter

He says if sex is mainly about giving pleasure, then the spouse with lower desire can sometimes give sexually as a gift of love. That should not be dismissed as inauthentic just because it did not begin with intense passion. Love often acts before feeling catches up. But the same principle applies to the spouse with higher desire. They also must give. Give patience. Give understanding. Give tenderness. Give emotional care. Give restraint. Give attention to context. Give safety. So the point is not that one person always yields to the other. The point is that both are asking, “How can I love?”

Simon

That is the guardrail. Because this teaching can be abused if only one side is told to give.

James Porter

Exactly. Mutual self-giving must be mutual. If one spouse uses the language of giving to get what they want, that is not Christian love.

Simon

Then Keller talks about context. He says, speaking generally from his own marriage, context did not matter much to him. But it mattered a lot to Kathy. And at first, he was slow to understand what that meant. He thought context might mean candles or some surface detail. But for Kathy, it meant emotional preparation. Warmth. Conversation. Connection.

James Porter

Yes. That is a very practical example. Many couples differ not only in frequency of desire, but in what makes desire possible. One person may experience desire quickly. Another may need emotional closeness first. One may feel rejected if sex is not spontaneous. The other may feel used if there has been no tenderness or connection. So they have to learn each other.

Simon

And that takes patience.

James Porter

Yes. Keller says it took years for them to become good at sexually satisfying each other. But the patience paid off. That is such a needed word. Married couples should not assume difficulty means incompatibility. It may mean there is learning to do. Conversation to have. Healing to seek. Habits to change. Trust to rebuild.

Simon

Then Keller says sex is a test. And that is a strong section. Because if sex is a sign and seal of the whole relationship, then issues in the relationship often show up in the sexual relationship.

James Porter

Right. A couple may think the problem is sexual compatibility. But underneath that may be guilt from past relationships. Fear. Anger. Mistrust. Disrespect. Unresolved conflict. Resentment. A feeling of being unseen. A lack of emotional safety. Sex is too sensitive to be separated from the rest of the marriage.

Simon

So if sex is not working, the answer may not be merely technique. It may be relational repair.

James Porter

Yes. Of course sometimes there are physical, medical, hormonal, trauma-related, or other issues that need appropriate care. But Keller’s point is that we should look beneath the surface. Sex often reveals what is happening elsewhere in the marriage.

Simon

That connects to Week 5. Marriage has the power of truth. It exposes. Even in the bedroom.

James Porter

Exactly. Sex can show you where there is fear, distance, anger, shame, or mistrust. That can be painful, but it can also become a gift if the couple is willing to address what is underneath.

Simon

Then Keller talks about change over time. He brings back Lewis Smedes’ idea that you do not marry one fixed person. You marry many versions of the same person over time. Bodies change. Energy changes. Children change things. Age changes things. Illness changes things. Stress changes things.

James Porter

Yes. A couple may have a sexual rhythm at one stage of marriage, and then life changes. Pregnancy. Babies. Sleep deprivation. Aging. Pain. Depression. Medical treatments. Grief. Work pressure. Hormones. A couple has to keep adapting. If they do not confront and adapt, sexual intimacy can erode.

Simon

So “never give up working on your sex life” does not mean obsess over it. It means do not abandon it.

James Porter

Right. Do not let embarrassment, frustration, or disappointment make the subject untouchable. Because if sex is like oil in an engine, then without it, the friction between all the moving parts of marriage can create heat, resentment, hardness, and distance. Sex is meant to be commitment glue. But if neglected or weaponized or avoided, it can become one more place of division.

Simon

That is direct, but true. And again, we need the balance: Working on sex may mean talking honestly. It may mean slowing down. It may mean pursuing counseling. It may mean medical help. It may mean trauma-informed care. It may mean repentance. It may mean rebuilding friendship. It may mean forgiving. It may mean learning. But it does not mean pressuring.

James Porter

Exactly. Love seeks healing, not control.

Simon

Then Keller ends with the glory of sex. And I think this is the most surprising ending. Because after all the practical counsel, he zooms out to the Trinity and the future kingdom. He says sex is glorious. Why?

James Porter

Because it reflects something of divine joy. From all eternity, Father, Son, and Spirit have delighted in one another. They glorify one another. They pour love and joy into one another. God is not lonely. God is love. God is eternal communion. And marital sex, in a creaturely and limited way, reflects self-giving delight.

Simon

So sex is not glorious because it is ultimate. It is glorious because it points beyond itself.

James Porter

Yes. That is very important. Sex is not God. Sex is not salvation. Sex is not the highest good. But it is a signpost to a greater joy. It points to the final union with Christ that believers will enjoy. The best marriages point to the deeper, final, infinitely satisfying union between Christ and His people.

Simon

That helps us understand both desire and limits. Desire matters because sex points to glory. Limits matter because sex is not the glory itself.

James Porter

Exactly. If you idolize sex, you crush it under divine weight. If you despise sex, you refuse a good signpost God created. If you receive sex as covenantal, self-giving, and penultimate, it can become what God designed it to be.

Simon

So the final chapter brings us back to the gospel. Sex points to union. Marriage points to Christ and the church. Singleness points to the sufficiency of Christ and the family of God. And all of it is meant to lead us to Jesus, not away from Him.

James Porter

Yes. That is the whole series in miniature.

Simon

Alright, so let’s make this practical. This chapter is going to land differently depending on who is listening. Some listeners are single and trying to live faithfully with desire. Some are dating and trying to discern boundaries. Some are married and struggling sexually. Some are married and doing well but need a deeper theological vision. Some are carrying sexual shame from the past. Some have been harmed by other people’s sexual sin. So James, where should someone begin?

James Porter

I would begin by naming which false view of sex you are most tempted to believe. Do you treat sex as just an appetite? Do you treat it as dirty? Or do you treat it as private self-expression? Those views produce very different problems. If sex is just appetite, you will resist boundaries. If sex is dirty, you will resist joy and vulnerability. If sex is merely self-expression, you will resist covenant and community.

Simon

That is a helpful diagnostic.

James Porter

Second, learn to say what sex says. Sex says, “I belong to you wholly.” So ask: Does the relationship actually support what the body is saying? Has there been a whole-life covenant? Has there been a public, permanent, exclusive promise? If not, then sex is saying more than the relationship is saying.

Simon

That is a very clear way to think about chastity.

James Porter

Third, for singles, cultivate the spousal love of Christ. Do not try to obey the Christian sexual ethic by willpower alone. Pray. Receive the love of Christ. Tell your heart the truth: No sexual experience can finally complete me. Christ is the union my soul ultimately needs.

Simon

That is not meant to minimize desire.

James Porter

No. It is meant to interpret desire. Sexual desire can be real and strong. But it points beyond itself.

Simon

Fourth?

James Porter

Build community. Chastity is not meant to be practiced in isolation. Find or help create a community where singles are honored, where marriage is not idolized, where honest conversation is possible, where people are not choosing partners merely by looks or money, where married families welcome singles into real life, and where sexual holiness is pursued together.

Simon

That is a lot. But it is probably necessary.

James Porter

It is. Fifth, practice gospel balance with sexual thoughts. Do not panic at every unwanted thought. Do not entertain and cultivate fantasies. When temptation comes, acknowledge it, refuse to nurse it, and bring it to God. And when you fail, confess without denial and receive grace without wallowing.

Simon

That is a needed balance.

James Porter

Sixth, decide where you will plant your foot before temptation comes. Do not wait until the emotional storm to decide whether God’s word has authority. Obedience has to be settled before desire starts arguing.

Simon

That ties back to the Jane Eyre story.

James Porter

Yes. Seventh, for married couples, talk about sex as part of your covenant. Not only as a problem. Not only as a source of pressure. Not only as a private performance category. Ask one another gently: What helps you feel safe? What helps you feel loved? What makes sex feel like union rather than pressure? What fears or frustrations have we avoided naming?

Simon

That conversation alone could help a lot of couples.

James Porter

Eighth, shift from getting to giving. Instead of asking first, “Am I getting what I want?” ask, “How can I love my spouse?” But both spouses must ask it. This is mutual. The lower-desire spouse asks how to give. The higher-desire spouse asks how to give. The emotionally distant spouse asks how to give. The spouse who needs emotional connection asks how to give. Self-giving must not become one-sided.

Simon

That is the key.

James Porter

Ninth, look beneath sexual problems. Do not assume every sexual difficulty is just technique or compatibility. Ask whether unresolved conflict, mistrust, shame, past wounds, physical pain, exhaustion, resentment, or emotional distance is showing up in bed. Then address the deeper issue.

Simon

And tenth?

James Porter

Never give up working on sexual intimacy in marriage. That may mean practical changes. Medical care. Counseling. Repentance. Rest. Better communication. Rebuilding affection. Patient learning. Whatever is needed. But do not simply let this part of the covenant die without attention.

Simon

That is practical. So the practices this week are: Name your false view of sex. Learn what sex says. Cultivate the spousal love of Christ. Build Christian community. Practice gospel balance with sexual thoughts. Plant your foot before temptation. Talk about sex as covenant. Shift from getting to giving. Look beneath sexual problems. And keep working patiently on sexual intimacy in marriage. That is a lot, but it follows the whole chapter.

Simon

Alright… let’s slow this down and reflect. We’re going to take these one at a time. If you’re listening alone, pause between them. If you’re with a group, let the questions breathe. Here’s the first question. Which false view of sex are you most tempted to believe? Sex as appetite? Sex as dirty? Or sex as private self-expression? How has that shaped your thinking, your shame, your choices, your marriage, your dating, or your expectations?

James Porter

That is a foundational question. Until you name the false story, it will keep shaping you quietly.

Simon

Second question. Do you believe the Bible has a high view or a low view of sex? What evidence from Scripture challenges your assumption? How does the goodness of creation, the incarnation, resurrection, Proverbs, Song of Solomon, and 1 Corinthians 7 reshape your view?

James Porter

This matters because obedience will feel very different if you think God is anti-body versus if you believe God created the body and called it good.

Simon

Third question. What does it mean that sex is not merely physical? When you hear “one flesh,” do you think only of physical union, or do you think of whole-life union? What changes if sex is body language for complete covenant self-giving?

James Porter

That question gets to the center of the chapter. Sex says something. The Christian ethic asks whether the relationship truthfully supports what sex says.

Simon

Fourth question. Keller says sex should not say less than the covenant says. Where does that challenge modern assumptions about dating, cohabitation, casual sex, pornography, or sexual experimentation?

James Porter

This is where the biblical view pushes hard against casualness. Not because sex is low, but because sex is high.

Simon

Fifth question. How does seeing sex as covenant renewal change the way married couples should think about it? Do you tend to view sex mostly as pleasure, duty, performance, release, conflict, or renewal?

James Porter

For married couples, this can be freeing. Sex is not just another task. It is a way to remember and renew union.

Simon

Sixth question. Where have you seen sex create attachment before commitment? Maybe in your own life. Maybe in people around you. How does that help explain why sex outside marriage can cause jealousy, pain, confusion, or staying too long in an unhealthy relationship?

James Porter

This question requires honesty. Many people have experienced the bonding power of sex without having language for it.

Simon

Seventh question. If you are single, what resources do you actually have for chastity? Do you have deep experience of Christ’s love? Do you have honest Christian community? Do you have friends pursuing the same convictions? Do you have married couples who make you part of their lives? Do you have places where you can talk openly and wisely?

James Porter

If the answer is no, that is not a reason to give up. It is a reason to build better support.

Simon

Eighth question. What lie does your heart believe in moments of sexual temptation? Does it say, “This will finally make me whole”? “This will prove I am desired”? “This will make the loneliness stop”? “This will make me feel powerful”? “This will comfort me”? “This will not matter”? What truth from the gospel answers that lie?

James Porter

Temptation is rarely only physical. It almost always carries a promise. You have to identify the promise before you can answer it.

Simon

Ninth question. What does it mean to plant your foot on God’s word when feeling, reason, loneliness, and desire are arguing the other way? Where do you need conviction before temptation comes?

James Porter

That question is not only for singles. Every Christian needs a place to stand when desire is loud.

Simon

Tenth question. How do you respond to sexual thoughts and desires? Do you treat unwanted thoughts as proof that you are filthy? Do you indulge them and let them build a fantasy life? What would gospel balance look like for you?

James Porter

The gospel gives both seriousness and mercy. It says do not make a nest for temptation, but also do not confuse temptation with condemnation.

Simon

Eleventh question. If you carry sexual shame, have you actually brought that shame into the gospel? Not minimized it. Not hidden it. Not let it define you. But confessed it, received cleansing, and allowed Christ’s grace to speak louder than your past?

James Porter

That may be one of the most important questions in the whole episode. Shame kept in the dark becomes powerful. Grace brings it into the light.

Simon

Twelfth question. For married couples: Do you think about sex more as getting or giving? What would it look like for both spouses to ask, “How can I give joy, safety, tenderness, and pleasure to the other?”

James Porter

Both spouses must answer that. If only one is asked to give, the biblical vision has been distorted.

Simon

Thirteenth question. Where have performance expectations harmed your view of sex? Have you treated sex as a test of adequacy, attractiveness, masculinity, femininity, technique, or success? What would it look like to stop performing and simply love?

James Porter

That is a healing question for many couples. Performance kills tenderness. Covenant love creates safety.

Simon

Fourteenth question. If desire levels differ in your marriage, how are you handling that difference? With resentment? Pressure? Avoidance? Shame? Silence? Or patient mutual self-giving?

James Porter

Difference in desire does not have to become a battlefield. But it will require honesty, humility, and care from both people.

Simon

Fifteenth question. What context does your spouse need for sexual intimacy to feel like love? Emotional warmth? Conversation? Rest? Affection during the day? Respect? Resolution of conflict? Privacy? Patience? Have you asked? Have you listened?

James Porter

This is where love gets specific. You cannot love well if you refuse to learn your spouse.

Simon

Sixteenth question. What might be showing up in bed that is actually rooted somewhere else? Unresolved conflict? Mistrust? Disrespect? Past guilt? Fear? Pain? Exhaustion? Resentment? A lack of friendship? What would it look like to address the deeper issue instead of only the symptom?

James Porter

Sex is a sensitive sign. If something is wrong there, look beneath the surface with humility.

Simon

Seventeenth question. How have time, age, children, illness, stress, or life changes affected sexual intimacy? Have you adapted? Or have you avoided the subject because it feels embarrassing, disappointing, or painful?

James Porter

Marriage changes over time. Love requires creative and disciplined adaptation.

Simon

Eighteenth question. Do you believe sex is glorious without making it ultimate? What changes if sex points to the joy of the Trinity and the future union with Christ, but is not itself the final joy?

James Porter

That is the biblical balance. Receive the gift. Do not worship the gift. Let the gift point you to God.

Simon

Nineteenth question. As we finish the series, which week challenged you most? The secret of marriage? The power for marriage? The essence of marriage? The mission of marriage? Loving the stranger? Embracing the other? Singleness and marriage? Sex and marriage? Where is God asking you to repent, heal, grow, or hope?

James Porter

That is a good closing reflection. The goal was never just to learn ideas about marriage. The goal was formation.

Simon

And finally, pray. If you are single, ask God for chastity that is not rooted in shame, but in hope. Ask Him for community. Ask Him for Christ’s love to become real to your heart. Ask Him for courage to plant your foot when temptation comes. If you are married, ask God to make sexual intimacy a place of mutual giving, safety, tenderness, honesty, and covenant renewal. Ask Him to expose and heal what needs attention. Ask Him to protect you from entitlement, avoidance, performance, and shame. And for all of us, ask God to help us receive sex as a good but penultimate gift — a signpost pointing to the greater joy of union with Christ.

James Porter

Yes. And pray with confidence. The God who created the body, redeemed the body, and will raise the body is not ashamed of our bodies. He is also not careless with them. His commands are not against our joy. They are for our joy.

Simon

That is a good word.

Simon

James, thank you. This was a difficult chapter, but also a beautiful one. Because Keller helps us see that the Christian view of sex is not prudish, and it is not permissive. It is not ashamed of the body, and it does not worship the body. It does not treat sex as dirty, and it does not treat sex as casual. It says sex is good. Sex is powerful. Sex is whole-personal. Sex is covenantal. Sex is meant to say with the body what marriage says with the whole life: I belong to you. Completely. Permanently. Exclusively. And because sex says that, it should not be used to say anything less. That is why chastity matters for singles. Not because sexual desire is bad. Not because the body is shameful. But because sex is too meaningful to be detached from covenant. And that is why sexual intimacy matters in marriage. Not as entitlement. Not as performance. Not as pressure. But as covenant renewal. As mutual giving. As love embodied. As a sign and seal of the union husband and wife have already promised to one another. And then Keller lifts our eyes even higher. Sex is glorious because it points beyond itself. It gives us a small, embodied glimpse of self-giving delight. It points to the love within the triune God. And it points forward to the final union we will have with Christ, where the ache beneath all our earthly desires will finally be answered. And since this is the final week, I want to step back and summarize what this whole eight-week series has been about. In Week 1, we began with the secret of marriage. We saw that marriage only makes sense through the gospel. Marriage is not mainly about finding a perfectly compatible soul mate who will meet every need without requiring change. It is about the mystery of Christ and the church. A covenant of self-giving love. Truth and grace. Sacrifice and transformation. In Week 2, we looked at the power for marriage. We saw that no one has the natural power to love like this for a lifetime. The power comes from the Holy Spirit making the gospel real to the heart. The Spirit makes Christ’s love so real that self-centered people can begin to serve, repent, forgive, and love without making a spouse their source of life. In Week 3, we looked at the essence of marriage. We saw that love is not mainly a feeling. It includes feeling, but it is deeper than feeling. It is covenant promise. It is future love. It is a vow that creates the safety where passion, vulnerability, and deep intimacy can grow over time. In Week 4, we looked at the mission of marriage. We saw that marriage is not finally about personal happiness, social status, romance, or even family stability. It is spiritual friendship. A husband and wife helping one another become the radiant people God is making them to be. In Week 5, we looked at loving the stranger. We saw that marriage reveals the real person — not only your spouse, but you. Marriage has the power of truth. The power of love. And it needs the power of grace so truth and love do not destroy each other, but transform. In Week 6, we looked at embracing the other. We talked about gender, difference, authority, submission, headship, helper, and the way Jesus redefines all of it. We saw that difference is a good but fallen gift, and that in Christ, authority becomes service and submission becomes strength. In Week 7, we looked at singleness and marriage. We saw that marriage is good, but it is not ultimate. And because marriage is not ultimate, singleness is not second-class. Christ is the true spouse. The church is the true family. The kingdom is the true future. That frees us to desire marriage without worshiping it, and to receive singleness without treating it as exile. And now in Week 8, we have looked at sex and marriage. We have seen that sex is not merely appetite, not dirty, and not private self-expression. It is a God-created sign and seal of covenant union, meant to express and renew whole-life self-giving love, and to point beyond itself to the glory of God and the final joy of union with Christ. So when you put all eight weeks together, this series was never just about how to have a better marriage. It was about seeing marriage through the gospel. And also seeing the gospel through marriage. It was about learning that human love is both more difficult and more glorious than we tend to think. It was about learning that our deepest problem is not incompatibility, but sin. Our deepest need is not a perfect spouse, but grace. Our deepest identity is not husband, wife, single, desirable, successful, wanted, or unwanted. Our deepest identity is found in Christ. And I hope that is what you got out of this series. Not just marriage tips. Not just theology in the abstract. But a clearer vision of Christ. A clearer vision of covenant love. A more honest view of yourself. A more hopeful view of marriage. A more dignified view of singleness. A more holy view of sex. And a deeper sense that the gospel is not a small religious addition to life. It is the center. It is the power. It is the pattern. It is the promise. Because whether married or single, every Christian is ultimately being prepared for the wedding feast of Christ and His people. That is where this whole series points. And if that is true, then marriage can be honored without being idolized. Singleness can be honored without being pitied. Sex can be honored without being worshiped. And every season of life can become a place where God forms us in the self-giving love of Jesus. So thank you for walking through these eight weeks with us. Take the reflection questions slowly. Talk about them honestly. Pray through them. Let the gospel work on the parts of your life that are easy to hide. And as always, keep walking the way. We’re grateful you’re here. We’ll talk again soon.
