Week 3 - The Essence of 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 continuing our eight-week journey through The Meaning of Marriage by Timothy Keller, written with Kathy Keller. This is Week 3, and the chapter is called The Essence of Marriage. And I think this chapter is really important because it answers a question that a lot of people think they already understand: What is love? That sounds simple. Everybody talks about love. Everybody wants love. Everybody has opinions about love. But this chapter slows us down and says: Be careful. Because if you misunderstand love, you will misunderstand marriage. And if you misunderstand marriage, you may end up expecting the wrong things from it, fearing the wrong things about it, or leaving too quickly when love does not feel the way you assumed it should feel. Last week, we talked about the power for marriage. We said the Holy Spirit makes the gospel real to the heart, and that Spirit-filled love is what enables us to serve, repent, forgive, and get ourselves out of the center. This week, Keller presses into the nature of love itself. And he does that by challenging one of the most common assumptions in modern culture: that love is, at its core, a feeling. A romantic feeling. A desire. A passion. A sense of chemistry. A sense of being emotionally drawn to someone. Now, Keller is not against feeling. He is not against romance. He is not against passion. This chapter is not cold. It is not saying marriage should be mechanical or loveless or merely dutiful. But it does say that if love is defined mainly by feeling, marriage becomes almost impossible to understand. Because feelings rise and fall. They fluctuate. They are affected by stress, sleep, work, hormones, conflict, disappointment, distraction, illness, and ordinary life. And if love means “I feel strong romantic desire right now,” then the moment that feeling weakens, people start to panic. Did I marry the wrong person? Are we falling out of love? Is the marriage dead? Should love be this much work?

James Porter

Yes. And those questions become very powerful when people have not been given a deeper definition of love.

Simon

Exactly. And Keller says the Bible gives us a deeper definition. Love is not less than affection, but it is more fundamental than affection. It is not less than romance, but it is deeper than romance. Love is active commitment to the good of another person. Love is giving yourself. Love is covenant. And that means the marriage vow is not just a “piece of paper.” It is not a bureaucratic add-on. It is not a romantic formality. It is at the center of what marital love is. So James, before we go further, when this chapter talks about the essence of marriage, what is it really trying to show us?

James Porter

Yeah… this chapter is showing us that the essence of marriage is covenant love. And covenant love is very different from the way modern culture usually defines love. Modern culture tends to measure love by intensity of feeling. How attracted am I? How passionate do I feel? How much does this person fulfill me? How much chemistry is there? How alive do I feel when I am with them? But the Bible measures love more by self-giving commitment. How much am I willing to give of myself for this person? How much freedom am I willing to surrender? How much time, emotional energy, attention, patience, forgiveness, and service am I willing to invest? And marriage is where that kind of love is formalized in a covenant.

Simon

So the vow is not opposed to love.

James Porter

No. That is one of the main points. A lot of people assume that legal obligation kills romance. They think love should be spontaneous. Uncoerced. Free. Purely emotional. And if obligation enters, then love becomes fake or oppressive. But Keller says the Bible sees covenant very differently. A covenant joins law and love. It is binding, but deeply personal. It is formal, but intimate. It is obligation, but not cold obligation. It is promise-shaped love. And that promise creates the space where love can become deeper, safer, more vulnerable, and more durable.

Simon

So marriage is not a consumer relationship.

James Porter

Exactly. In a consumer relationship, the individual’s needs are more important than the relationship. You stay as long as the product or service meets your needs at a cost you are willing to pay. If the cost goes up or the benefit goes down, you leave. But in a covenant relationship, the good of the relationship takes priority over immediate personal preference. That does not mean there are no serious covenant-breaking sins. The chapter addresses divorce and says there are biblically recognized grounds in cases like adultery and willful desertion. But ordinary difficulty, fading feelings, disappointment, or costliness do not cancel the covenant. The vow keeps you there long enough for love to grow through seasons where feelings are weak.

Simon

That is a major idea.

James Porter

Yes. And Keller spends much of the chapter showing that promise does not kill passion. It actually gives passion a place to mature. Early romance is often powerful, but it is also shallow in the sense that you do not yet know the person fully, and they do not yet know you fully. Over time, through promise, repentance, forgiveness, truth-telling, suffering, and shared life, a deeper love can grow. Not the same as the first rush of attraction. But richer. Quieter. Stronger. More secure. A love where you are fully known and truly loved.

Simon

And that is the famous line from the chapter. To be loved but not known is comforting but superficial. To be known and not loved is terrifying. But to be fully known and truly loved is something close to being loved by God.

James Porter

Yes. That is one of the central claims. And then Keller brings this into daily practice. Love is commanded in Scripture, which means love cannot be only emotion. Emotions cannot be commanded. Actions can. So we are called to do the actions of love, even when the feelings are weak. And as we do the actions of love, over time, the feelings often follow.

Simon

So the essence of marriage is not feeling instead of promise. And it is not promise instead of feeling. It is promise that creates the conditions for feeling to deepen.

James Porter

Exactly. Covenant love unites duty and delight. Action and affection. Promise and passion. And ultimately, it points us again to Christ. Jesus did not love us because we were lovely. He loved us in order to make us lovely. He stayed. He gave Himself. And that is the pattern for marital love.

Simon

That gives the chapter real shape. So just to summarize, what we’re looking at today is this: The essence of marriage is a covenant promise of future love that creates the security where romance, vulnerability, faithfulness, and deep joy can grow over time.

James Porter

Yes. That’s exactly right.

Simon

And the chapter will walk us through love and the “piece of paper,” the danger of defining love too subjectively, the difference between consumer and covenant relationships, the vertical and horizontal nature of marriage vows, the power and freedom of promising, the way promise deepens passion, and then how actions of love can lead to feelings of love. So with that in mind… let’s move into the deep dive.

Simon

Alright… so Keller opens the chapter with a scene from a television drama. A man and woman are living together. He wants to get married. She does not. And eventually she says something like: Why do we need a piece of paper to love each other? I don’t need a piece of paper to love you. It only complicates things. And Keller says that statement stuck with him because he had heard essentially the same thing from younger adults for years. Why begin there?

James Porter

Because that objection reveals a definition of love. The woman is assuming that love is basically romantic feeling. She feels passion. She feels affection. She feels desire. And she is saying, “A legal commitment does not add to that feeling. It may even threaten it.” If love is mainly a feeling, then the marriage vow can look unnecessary or even dangerous.

Simon

So in that framework, the “piece of paper” is external to love. It is legal. Love is internal. It is emotional. And the legal thing feels like it can only complicate the emotional thing.

James Porter

Exactly. But Keller says the Bible defines love differently. Biblical love is measured not primarily by how much you want to receive from someone, but by how much you are willing to give yourself for someone. How much freedom are you willing to forsake? How much time, money, emotion, patience, and care are you willing to invest? How much are you willing to lose for the good of the other? That is where the marriage vow becomes very important. Because the vow is not a random legal accessory. It is a test of whether love has reached the level of covenant.

Simon

So when someone says, “I love you, but I don’t want to get married,” Keller says there may be something else underneath that. They may really be saying: “I do not love you enough to close off my options.” “I do not love you enough to give myself that thoroughly.” “I love you at some level, but not at the marriage level.”

James Porter

Yes. And that is a hard statement, but it clarifies the issue. A person may have real affection. Real attraction. Real enjoyment. But if they refuse covenant, then something is being withheld. The Bible’s view is that marriage-level love involves a public, binding, exclusive promise.

Simon

And Keller is careful not to say emotion does not matter. He says a marriage with no passion or emotional desire does not fulfill the biblical vision either. So he is not saying love is duty instead of emotion. He is saying emotion cannot be the foundation.

James Porter

Right. The Bible does not pit romantic love against sacrificial commitment. It brings them together. The problem comes when we define love primarily as emotional desire. Then duty and desire become enemies. And Keller says that is unrealistic and destructive.

Simon

That leads into the next section: the overly subjective view of love. And this is where Keller says modern people think of love so subjectively that if duty is involved, they assume something has gone wrong. He especially applies that to sex. Many people think that if a spouse has sex to please the other spouse when they themselves are not already in a mood of strong desire, that must be inauthentic or oppressive. Now, this is delicate, because obviously sex should never involve coercion or pressure or disregard for the other person. But Keller is making a different point. What is he saying?

James Porter

He is saying that if sex in marriage must always wait for both spouses to feel spontaneous passion at exactly the same time, then sex may become less and less frequent. And as it becomes less frequent, desire may weaken further. So a subjective, feeling-only view of love can create a cycle where passion actually diminishes. He is not defending manipulation or coercion. He is challenging the idea that love is only authentic when it begins with intense emotion.

Simon

So sometimes action can lead feeling, not just follow feeling.

James Porter

Yes. And that becomes a major theme of the chapter. In marriage, sex is not meant to be an arena where each person performs or impresses. It is meant to be a gift of self. A way of giving joy. A way of expressing covenant union. A way of knowing and being known. And that means it can still be meaningful, loving, and even mood-changing when it begins as an act of giving rather than a burst of spontaneous passion.

Simon

Keller contrasts sex outside marriage and sex inside marriage. He says sex outside marriage often comes with the thrill of pursuit. The thrill of the unknown. The desire to impress, entice, and win someone. Risk, uncertainty, and pressure can heighten the feeling. And if that is what someone means by “great sex,” then yes, marriage will not preserve that exact thrill. Because marriage is not the thrill of the hunt.

James Porter

Right. But Keller says that is not the only kind of passion. And it is not the best kind. The passion of marriage is meant to grow from safety, vulnerability, mutual giving, and joy in giving the other person joy. He tells his own story with Kathy. They were virgins when they married. Their wedding night was awkward and discouraging. It was not a performance. There was no practiced skill, no attempt to impress. But over time, their sexual relationship grew because it was built around tenderness, vulnerability, and giving rather than performance.

Simon

That is such an important reframing. Because our culture often teaches people to think of sex as performance. Am I desirable? Am I impressive? Was it exciting? Was it novel? Was it intense? But Keller says the best marital sex is not about basking in the glow of performance. It is about the joy of giving and receiving love with someone to whom you are wholly given.

James Porter

Yes. And that means marriage does not kill real sexual love. It changes the kind of love sex expresses. It moves away from conquest, risk, and ego. It moves toward covenant, vulnerability, and joy in the other.

Simon

Then Keller introduces the major contrast of the chapter: consumer or covenant. He says the Bible teaches that the essence of marriage is sacrificial commitment to the good of the other. But he also warns against the opposite error. Some traditional societies made marriage merely a social transaction. A duty to family, tribe, or society. So modern culture makes the individual’s happiness ultimate. Traditional culture can make family interest ultimate. But the Bible makes God ultimate. How does that shape the biblical view of marriage?

James Porter

It allows the Bible to unite things that other views often separate. Feeling and duty. Passion and promise. Personal love and moral obligation. Because God is the supreme good, marriage is not merely for individual self-fulfillment, and it is not merely for family advancement or social order. It is a covenant before God. That covenant gives marriage its shape.

Simon

So what is a consumer relationship?

James Porter

A consumer relationship lasts as long as the vendor meets your needs at a cost you are willing to pay. If someone else offers a better product, better service, or a lower cost, you switch. In consumer relationships, the needs of the individual are more important than the relationship.

Simon

And Keller says that marketplace way of thinking has spread into relationships. We stay connected to people as long as the relationship meets our needs at an acceptable cost. When the cost rises, or when the emotional profit seems too low, we cut our losses.

James Porter

Yes. And that is very destructive when applied to marriage. Because every marriage will eventually become costly. Every spouse will disappoint. Every marriage will require seasons where you give more than you feel you are receiving. If marriage is treated as consumer exchange, then those seasons become reasons to withdraw. But covenant says something different. In covenant, the good of the relationship takes priority over immediate personal preference.

Simon

Keller gives the parent-child relationship as an example of a covenantal relationship that our society still recognizes. A parent may get little emotional return from caring for an infant. The child is needy, exhausting, expensive, and gives very little back at first. But we would rightly consider it terrible for a parent to abandon a child simply because the relationship is difficult or unrewarding. Why? Because the parent-child bond is covenantal, not consumer.

James Porter

Exactly. The child does not have to provide sufficient emotional profit in order to be loved. The relationship itself carries obligation. And Keller says marriage is also covenantal. The problem is that covenant is becoming increasingly foreign to modern people.

Simon

So then he moves to the vertical and horizontal nature of covenant. He says the Bible is full of covenants. Some are horizontal — between people. Friendships. Nations. Agreements. But the most prominent are vertical — God making covenant with individuals, families, and peoples. Marriage is unique because it has both strong horizontal and vertical dimensions. Explain that.

James Porter

Marriage is a covenant between husband and wife. That is the horizontal dimension. But it is also made before God and with God as witness. That is the vertical dimension. Keller points to passages like Malachi and Proverbs, where marriage is described as a covenant made before God. So to break faith with your spouse is also to break faith with God.

Simon

That helps explain the traditional wedding service. Because there are often questions before vows. The minister asks each person whether they will take the other as spouse, whether they will promise love, honor, duty, service, faith, tenderness, and lifelong care. And they answer, “I will” or “I do.” But at that point, they are not yet speaking directly to each other. They are answering before God.

James Porter

Yes. Keller says they are speaking vertically before they speak horizontally. They first make a vow before God, in front of witnesses, under the authority structures of church and state. Then they turn and make vows directly to one another. That vertical covenant strengthens the horizontal covenant.

Simon

He uses the image of an A-frame house. The two sides lean together and support each other at the top. But beneath both sides is a foundation. The covenant before God is the foundation that supports the covenant between the spouses.

James Porter

Right. That is why marriage is the deepest human covenant. It is not just a private promise between two people. It is a promise before God.

Simon

Then Keller moves into the relationship between love and law. And this is where he says covenant is a blend of law and love. That sounds strange to modern ears because we tend to think law and love are opposites. Law is obligation. Love is freedom. Law is duty. Love is desire. Law is external. Love is internal. But Keller says a covenant is more intimate because it is binding. How does that work?

James Porter

A marriage vow is itself an act of love. To promise yourself to someone publicly, exclusively, and permanently is not a mere legal formality. It is a radical gift. You are saying, “I am closing off other options. I am binding myself to you. I am giving you security. I am making my future available to you.” That does not weaken love. It deepens love.

Simon

So someone who says, “I love you, but we do not need marriage,” may be withholding the very kind of love marriage requires.

James Porter

Yes. They may be saying, “I want affection without final commitment. I want closeness without surrendering freedom. I want the benefits of marriage without the covenant.” Keller says the willingness to make the vow is proof that love has reached marriage level.

Simon

And then he makes another point. The legal bond creates security. When dating or living together, there can be a sense that you have to keep proving your value. Keep the chemistry alive. Keep being fun. Keep being attractive. Keep being impressive. Because if the relationship stops meeting the other person’s needs, they can leave.

James Porter

Yes. That is the insecurity of a consumer relationship. You are always marketing yourself. But in marriage, the covenant creates a space where you can stop performing. You can reveal your true self. You can be vulnerable. You can put down defenses. You can be emotionally and physically naked without constant fear that the other person will simply walk away.

Simon

That is such a powerful idea. The law of the vow creates a place where love can become more personal, not less.

James Porter

Exactly. The promise creates safety. And safety allows deeper intimacy.

Simon

Keller also says this fits our instincts. When people fall in love, they naturally want to make promises. They do not usually say, “I feel something for you now, but who knows about tomorrow.” They say things like, “I will always love you.” They want permanence. They want assurance. They want the other person to promise it too.

James Porter

Yes. And that instinct points to the fact that real love desires permanence. The Song of Solomon expresses love as strong, unyielding, and not easily quenched. True love does not want to remain provisional. It wants to say, “I am yours.”

Simon

Then Keller gives one of the most important distinctions in the chapter: Wedding vows are not mainly a declaration of present love. They are a promise of future love. That line is huge.

James Porter

It is. He tells about attending a wedding where the couple wrote vows that amounted to, “I love you and want to be with you.” That is meaningful as an expression of present feeling, but it is not really a vow. A vow is not simply saying what is true today. It is binding yourself to what you will do tomorrow. And next year. And in sickness. And in disappointment. And in want. And in sorrow. And when feelings fluctuate.

Simon

So a wedding is not mainly celebrating how loving two people feel at the moment. That can be assumed. It is the moment where they promise to be loving in the future, regardless of changing internal feelings or external circumstances.

James Porter

Yes. That is covenant. A promise of future love.

Simon

Keller illustrates this with Ulysses and the Sirens. Ulysses knows that when he hears the Sirens, he will temporarily lose his mind. So before that happens, while he is still thinking clearly, he has himself tied to the mast. He tells his men not to listen to him when he starts yelling. Keep going. Do not let me destroy myself while I am temporarily insane. How does that relate to marriage vows?

James Porter

Marriage vows tie us to the mast. There will be seasons when feelings are confused. When anger is high. When disappointment is loud. When attraction is low. When resentment is tempting. When you are not seeing clearly. And the vow says, “Do not make a permanent decision based on temporary emotional insanity.” Stay long enough for the mind to clear. Stay long enough for repentance, forgiveness, counsel, time, and grace to do their work.

Simon

Keller connects that with the research he mentioned earlier — that many unhappy marriages become happy within several years if people stay married and do not divorce. His point is not that every marriage must remain no matter what. He does talk about divorce. But he is saying vows keep us from running too quickly.

James Porter

Right. The vow is not a prison. It is a stabilizer. It gives love a chance to deepen through rough seasons.

Simon

Let’s talk about divorce carefully because Keller does. He quotes Jesus in Matthew 19, where the Pharisees ask if a man can divorce his wife for any reason. Some teachers in that day allowed divorce for nearly any displeasure. Jesus rejects that. He goes back to Genesis and says what God has joined together, people should not separate. So Jesus clearly rejects casual divorce.

James Porter

Yes. Jesus confirms that marriage is a covenant and that it creates a deep unity. It cannot be discarded lightly. To allow divorce for almost any reason would hollow out the meaning of covenant.

Simon

But Jesus also does not say there are no grounds for divorce. Keller says because of the hardness of human hearts, there are severe covenant violations that can break the marriage bond. Jesus names adultery in Matthew 19. Paul adds willful desertion in 1 Corinthians 7.

James Porter

Yes. And that balance matters. Divorce should not be easy. It should not be the first, second, third, or fourth resort. But the Bible also recognizes that some covenant violations are so severe that the wronged spouse is not bound in the same way. Keller is especially careful to say that the wronged party should not live in shame.

Simon

So the chapter is not using covenant to trap people in shame after severe betrayal or abandonment. But it is using covenant to resist a consumer view that leaves whenever the relationship is no longer satisfying.

James Porter

Exactly. Covenant is strong. But it is not blind to sin.

Simon

Then Keller talks about the power of promising. He says vows fortify us. They keep us from running out too quickly. They create stability. And that stability allows feelings of love — especially early, fragile feelings — to grow stronger and deeper over time. He brings in W. H. Auden’s idea that marriage, as a creation of time and will, is more interesting than romance, however passionate. What does that mean?

James Porter

Romance can be intense, but it can also be shallow and temporary. Marriage, over time, becomes complex, layered, tested, and rich. It contains memory. Shared suffering. Forgiveness. Disappointment. Reconciliation. Ordinary life. Aging. Laughter. Failure. Service. A romance may be thrilling, but a marriage becomes a world.

Simon

That’s a great way to say it. A romance may be thrilling, but a marriage becomes a world.

James Porter

Yes. And that world is built by promise.

Simon

Keller then discusses Lewis Smedes and “the power of promising.” This section is fascinating because it says promises do not just shape relationships. They shape identity. Smedes argues that we are not finally defined by feelings, because feelings flicker. We are not finally defined by achievements, because achievements do not reveal the whole self. We are not even finally defined by our idealized self-image. We are shaped by the promises we make and keep.

James Porter

Yes. And that is a profound idea. A promise gives continuity to the self. When I make a wise promise and keep it, I become someone stable. Someone who can be trusted. Someone whose future is not completely controlled by passing feelings or changing circumstances.

Simon

Keller uses the story of Thomas More from A Man for All Seasons. More’s daughter wants him to say the words of an oath while inwardly thinking something else, so that he can save his life. But More refuses because an oath is not just words. It is a person holding himself in his own hands. If he opens his fingers, he loses himself.

James Porter

Right. The point is that oath-breaking does not merely break a rule. It fractures the self. If my promises mean nothing, then I become unstable. My relationships cannot rely on me. Even I cannot rely on me.

Simon

And Keller applies that to marriage. Smedes says when he married his wife, he did not know what he was getting into. He did not know how much she would change. He did not know how much he would change. He says his wife had lived with several different men during the marriage, and every one of them was him. Meaning, he changed over time. But the promise held the identity together.

James Porter

Exactly. The promise says, “I am the one who will be there with you.” Even as I change. Even as you change. Even as circumstances change. The vow becomes the connecting thread.

Simon

That connects directly to what we talked about in Week 1. You never marry a perfectly fixed person. You marry someone who will change. And you will change too. The promise is what lets love stay present through those changes.

James Porter

Yes. Without promise, every change becomes a potential reason to leave. With promise, change becomes part of the journey of learning to love the real person over time.

Simon

Then Keller makes a surprising claim: Promising is not the enemy of freedom. It is the means to freedom. That sounds opposite of how many modern people think. We often assume freedom means keeping options open. No binding commitments. Maximum flexibility. No permanent ties. But Keller says promises actually create deeper freedom. How?

James Porter

When you make a promise, you limit certain options now in order to have better, fuller options later. A person who refuses all commitments may preserve surface-level freedom, but they lose the freedom to build deep trust. They lose the freedom to be relied upon. They lose the freedom to create a sanctuary of stability in an unpredictable world.

Simon

So the person who says, “I want to stay free, so I won’t promise,” may actually be enslaved to mood, impulse, fear, and circumstance.

James Porter

Yes. Kierkegaard will make that point later in the chapter too. A person who refuses binding commitments in order to follow feelings is not truly free. They are controlled by feelings. A promise lets you rise above the conditioning of your past, the instability of your emotions, and the pressure of circumstances. It says, “This is who I will be.”

Simon

So promising is one of the uniquely human things we do. A dog cannot promise. A machine cannot promise. Only a person can bind the future self by a word given now.

James Porter

Exactly. And in that sense, a promise is an expression of freedom, not a denial of it.

Simon

Then Keller turns to promise and passion. And this may be one of the most beautiful parts of the chapter. He asks: How is long-term love superior to early romance? What is actually better about love built over time? And he says when you first fall in love, you think you love the person, but you don’t fully. Because you do not know them yet. You love your idea of them. Your experience of them. The version you can see.

James Porter

Yes. That is not meant to be cynical. Early love can be real. But it is incomplete. You do not yet know the other person fully. And they do not know you fully. You are both presenting your best selves. You are hiding some flaws. Some flaws you do not even know yet. Marriage will reveal things that dating cannot reveal.

Simon

And Keller says the early emotional high is often fueled by ego gratification. Someone thinks you are wonderful. Someone chooses you. Someone desires you. That is thrilling. But part of the thrill is that the person does not yet really know you. So there can be an insecurity under the excitement. “If they knew everything, would they still love me?”

James Porter

Yes. And that is why deep marital love is so powerful. Over years, someone sees you at your worst. They know your strengths and flaws. They know your weaknesses, habits, sins, moods, fears, and inconsistencies. And still they commit themselves to you. That is a profound experience.

Simon

This is where Keller gives the line we mentioned earlier: To be loved but not known is comforting but superficial. To be known and not loved is our greatest fear. But to be fully known and truly loved is like being loved by God.

James Porter

Yes. That kind of love liberates us from pretense. It humbles us out of self-righteousness. And it fortifies us for difficulty. It is not passionless. But it is a different kind of passion.

Simon

Keller compares early passion to a shallow, noisy brook and mature marital passion to a quieter, deeper river. At first, holding Kathy’s hand gave him an electric thrill. Decades later, the feeling is not the same buzz. But now it carries all the shared life, repentance, forgiveness, burdens, reconciliation, and knowledge of one another. The passion is deeper because the knowing is deeper.

James Porter

Exactly. And that is one of the central arguments of the chapter. Passion may lead you to make the promise, but the promise makes the passion deeper.

Simon

Then Keller brings in Kierkegaard to answer the objection that lifelong commitment must be the enemy of romantic love. Kierkegaard describes three outlooks on life: the aesthetic, the ethical, and the religious. This can feel philosophical, but it is very practical. What is the aesthetic person?

James Porter

The aesthetic person judges life mainly by whether something is interesting, exciting, beautiful, entertaining, or thrilling. The question is not first, “Is this good?” It is, “Does this fascinate me?” Now, Keller says the aesthetic aspect of life is not bad. Beauty and delight matter. But when the aesthetic dominates, it creates major problems.

Simon

Because the aesthetic person thinks he is free, but he is actually controlled.

James Porter

Yes. That is Kierkegaard’s point. The person who follows feeling wherever it leads may think, “I am free. I am not bound by tradition, duty, or expectation.” But in reality, he is ruled by mood, taste, impulse, and circumstance. If the spouse loses beauty, he loses interest. If illness comes, life feels meaningless. If excitement fades, he goes looking elsewhere. That is not freedom. It is slavery to changing conditions.

Simon

So true freedom is not the absence of obligation. True freedom comes when feeling is linked to obligation. When I commit myself to loving in action regardless of emotional fluctuation, I am not simply a pawn of circumstance.

James Porter

Exactly. And Kierkegaard says marriage does not destroy romantic love. It helps romantic love fulfill itself. Romantic love longs for permanence, but it cannot create permanence by itself. Covenant gives romantic love the stability it wants but cannot produce on its own.

Simon

That sentence is really helpful. Romantic love wants forever. But feelings alone cannot guarantee forever. Covenant gives romance a structure where forever can actually be pursued.

James Porter

Yes. And over time, the promise allows you to learn who the other person truly is, what they need, how to serve them, and how to enjoy them in ways that early romance cannot yet know.

Simon

Then Keller moves to emotion and action. And he makes a simple but important point: The Bible commands us to love our neighbor. But emotions cannot be commanded. You cannot simply command yourself to feel warm affection. So biblical love must primarily involve actions.

James Porter

Yes. That does not mean affection is unimportant. Affection is a natural and beautiful part of love. And when action and affection come together, that is deeply satisfying. But if we define love as affection, then we create huge barriers to loving people. Because feelings are inconsistent. They are tied to physical, psychological, and social factors. They wax and wane. Actions are more directly under our control.

Simon

Keller says many likes and dislikes are not virtues or sins. They are more like preferences in food or music. The question is what we do with them. If I only act lovingly when I feel affection, I will be a terrible friend, spouse, family member, and church member.

James Porter

Yes. And he gives a great example. If a parent gives up a day off to take a child to a ballgame, even when the parent does not feel especially affectionate toward the child at that moment, that may be more loving than doing it when the parent is full of warm feelings. Because when you feel delight in someone, meeting their needs can be rewarding to your own ego. But when you do the action of love without the emotional reward, you may be seeking their good more purely.

Simon

That is counterintuitive. We tend to think action without feeling is fake. Keller says sometimes action without feeling may be especially loving.

James Porter

Yes. Because love is willing the good of the other. And sometimes that means acting before the feelings arrive.

Simon

Keller also warns that feelings of love can lead us to love unwisely. Parents can spoil children because they cannot bear the child’s displeasure. Spouses can enable destructive behavior because they are afraid to lose affection. So strong feelings do not automatically make love wise.

James Porter

Exactly. Sometimes we are not loving the person. We are loving the approval, affection, or emotional comfort we get from the person. That is why love must be guided by action, truth, and the good of the other.

Simon

Then he brings in C. S. Lewis. Lewis says we should not waste time trying to manufacture feelings of love. Instead, act as if you love someone. Do the good. And over time, you may find that you come to love them more.

James Porter

Yes. Lewis says the principle works both directions. If you injure someone you dislike, you will dislike them more. If you do good to them, you will dislike them less. Actions shape affections. Cruelty deepens hatred. Kindness can grow love.

Simon

That is both encouraging and sobering. Because it means my actions are training my heart.

James Porter

Exactly. Every act is formative. If I withdraw, criticize, punish, and neglect, my feelings will likely follow that path. If I serve, listen, forgive, and bless, my feelings may begin to follow that path too.

Simon

Keller illustrates this from his early pastoral ministry. He says as a young pastor he had to love people he would not naturally have chosen as friends. Not because they were bad people, but because there was no natural spark or shared affinity. But as a pastor, he visited them. Answered late-night calls. Went to hospitals. Sat in homes. Attended family events. Listened. Served. Counseled. Shared life. And over time, something changed. He came to like them.

James Porter

Yes. And he is clear that this was not because he was especially holy. It was because he stumbled into Lewis’s principle. He did the actions of love before he felt the affections of love. And his emotions began to catch up with his behavior.

Simon

That is such a practical insight. If you love the unlovely in a sustained way, they may eventually become lovely to you. Not because they changed first. But because your heart changed through the actions of love.

James Porter

Yes. And that is crucial for marriage. Our culture says feelings of love are the basis for actions of love. Keller says that is sometimes true. But it is more consistently true that actions of love lead to feelings of love.

Simon

Then Keller talks about deciding to love. He points to Ephesians 5:28, where Paul says husbands ought to love their wives. That is command language. Obligation language. And Keller says emotions cannot be commanded. Actions can. So Paul is calling husbands to actions of love.

James Porter

Yes. And Keller immediately clarifies what he is not saying. He is not saying emotions do not matter. He is not saying you should deliberately marry someone you do not like. He is not saying attraction is irrelevant. But he says whoever you marry, you will at times fall “out of like” with them. Feelings of affection and delight cannot remain constantly intense. They will ebb and flow.

Simon

That is so important for people to hear before they panic. Because our culture glorifies romantic passion so much that when feelings dip, people think it proves something is wrong. “If this were the right person, my feelings would not be so up and down.”

James Porter

Yes. But Keller says that is false. Feelings fluctuate in every marriage. So in dry spells, you do the acts of love. You may not feel tender, eager, or sympathetic. But you act tenderly. You act understandingly. You act forgivingly. You act helpfully. And over time, the dry spells may become less frequent and less deep.

Simon

So love becomes more stable as action trains affection.

James Porter

Yes. That is what it means to decide to love.

Simon

Keller again uses C. S. Lewis’s idea that certain things must die in order to live. The early thrill cannot be preserved by clutching at it. If you try to keep the initial high forever, you may destroy the possibility of deeper love. You let that immature form of love die, and then through covenant action, it rises into something quieter, wiser, and richer.

James Porter

Exactly. The early ego-heavy attraction must be transformed. If people refuse that transformation, they become vulnerable to affairs. Because someone new may seem to offer the original thrill again. But that thrill will fade too.

Simon

Lewis also says “falling in love” is not as irresistible as people claim. People act as if it is like catching measles. It just happens to you. But Keller says we are responsible for how we cultivate or redirect attraction. If our minds are filled with sentimental stories, alcohol, fantasy, resentment, or self-pity, we may turn any attraction into “being in love.”

James Porter

Yes. That is a necessary warning. Attraction may arise without our choosing it. But what we do with attraction is our responsibility. We do not have to feed every feeling. We do not have to narrate every attraction as destiny. We do not have to turn every spark into a fire.

Simon

That is a strong word. Especially in a culture that treats desire as authority.

James Porter

Yes. Desire is not lord. Christ is. And covenant tells desire where it belongs.

Simon

Then Keller returns to the “piece of paper.” And he basically says: If you love someone in the biblical sense — if you want to share your life with them — then you should be willing to make a legal, permanent, exclusive commitment. The paper matters because the promise matters.

James Porter

Exactly. The paper is not magic. But the vow it represents is central.

Simon

Then the chapter shifts to “The Bargain.” And Keller says in ancient times there was a bride price. A prospective husband brought a sum to the woman’s father. We look back and say, “How awful.” But Keller says now, because we are more democratic, men and women do it to each other. We size each other up. Assets and liabilities. Good deal. Bad deal. What someone brings to the table.

James Porter

Yes. That is a sharp observation. We may no longer use formal bride price language, but we still often think in market terms. What does this person offer me? Status. Beauty. Money. Affection. Stability. Personality. Sex. Family. Social fit. Potential. We may not say it crudely, but we are often calculating.

Simon

And then after marriage, when we begin to see flaws, we evaluate the investment. “I am not getting what I expected.” “She is not being the wife I thought she would be.” “He is not being the husband I hoped he would be.” So if the return goes down, I reduce the investment. I stop serving as much. I become emotionally remote. I withdraw affection. I stop trying. And I tell myself it is fair.

James Porter

Yes. But Keller says that is really a form of revenge. It sounds like equity. But it is payback. “You are not giving me what I want, so I will give you less of what you need.”

Simon

And of course the spouse responds. They feel the withdrawal. So they dial back too. Less affection. Less service. Less effort. Less patience. And the marriage spirals down.

James Porter

Exactly. A consumer marriage is always vulnerable to that downward spiral.

Simon

Then Keller contrasts that with parenting. A child is incredibly needy. For years, the child gives far less than they receive. Parents sacrifice time, sleep, money, energy, and freedom. And the child may later rebel or become difficult. But the parent keeps giving. And after years of doing actions of love, the parent loves the child deeply. Even if the child is not attractive to anyone else.

James Porter

Yes. Because with children, the biblical pattern of love is almost forced on us. We do the actions of love regardless of whether we are getting equal return. And those actions deepen affection.

Simon

Then Keller says something really striking. After children leave home, many marriages fall apart because the parents treated their children covenantally but treated their marriage as consumer. They kept doing loving actions for the children regardless of feelings. But in the marriage, they withdrew actions of love when feelings faded. So after two decades, the parent-child bond is strong, but the marriage is empty.

James Porter

Yes. That is a sobering warning. The love you feed through action grows. The love you starve through withdrawal weakens.

Simon

Then Keller brings us to the final section: He Stayed. And this is where the chapter becomes very explicitly gospel-centered. He anticipates someone saying: “I cannot give love if I do not feel it. I cannot fake it. That is too mechanical.” And Keller says Paul does not call us to naked action alone. He calls us to think as we act. “Husbands, love your wives as Christ loved the church and gave Himself for her.” So what are we supposed to think about?

James Porter

We are supposed to think about Jesus. When Jesus looked down from the cross, He did not love us because we were attractive, faithful, impressive, or easy to love. We were denying Him. Abandoning Him. Betraying Him. And He stayed. He prayed for forgiveness. He gave Himself. He loved us not because we were lovely, but in order to make us lovely.

Simon

That is the heart of Christian love. He stayed.

James Porter

Yes. And that becomes the pattern for marriage. Not because spouses are saviors. Not because we can atone for sin. Not because every situation is safe or simple. But because the love of Christ teaches us what covenant love is. It is not based on the present loveliness of the beloved. It is committed to the good and future beauty of the beloved.

Simon

So Keller is saying: Speak to your heart. Remind yourself of Christ. Do not merely grit your teeth. Do not merely perform duty. Think about the One who stayed for you. Let His love define what love is. Then fulfill the promises you made.

James Porter

Exactly. This takes us back to everything we have said in the first three weeks. Week 1: marriage displays the gospel. Week 2: the Spirit gives the power for gospel-shaped love. Week 3: the essence of marriage is covenant promise, a promise of future love that acts faithfully even when feelings fluctuate.

Simon

That brings the whole chapter together. Love is not less than feeling. But it is more than feeling. Marriage is not merely a legal paper. But the vow is central. Promise does not kill passion. It creates the security where passion matures. Actions of love are not fake when feelings are weak. They may be the very path by which feelings grow. And Christ is the ultimate pattern. He loved. He gave. He stayed.

James Porter

Yes. That is the essence of marriage.

Simon

Alright, so let’s make this practical. This chapter touches almost everything: dating, sex, vows, romance, consumer thinking, divorce, promise, action, emotion, parenting, and the gospel. But the practical question is simple: How do we begin living by covenant love instead of consumer love? James, where should someone start this week?

James Porter

I would start with a diagnostic question: Where do I treat relationships like a consumer? That may be marriage. It may be dating. It may be friendship. It may be church. Ask: Where do I stay engaged only as long as the relationship benefits me at an acceptable cost? Where do I withdraw when the return feels too low? Where do I reduce my love because I feel I am not getting enough back? That question exposes the bargain mindset.

Simon

That is a strong place to begin. Because consumer love often feels fair to us. “I’m just matching their effort.” “I’m just protecting myself.” “I’m not going to keep giving if they aren’t giving.” But Keller says that can become revenge disguised as fairness.

James Porter

Yes. A second practice would be: Identify one way you have been reducing your actions of love because your feelings are weak. Maybe you have become less affectionate. Less patient. Less attentive. Less helpful. Less interested. Less prayerful. Less willing to listen. Less generous with encouragement. Name it. And then choose one action of love to restore. Not because the feeling is already there. But because love acts.

Simon

That is very concrete. Do the action of love. Not to fake it. But to train the heart and seek the other person’s good.

James Porter

Exactly. A third practice is to revisit the meaning of your promises. If you are married, think about the vows you made. Not just as a memory of your wedding day, but as a present identity. “I am the one who promised to be here.” “In plenty and want.” “In joy and sorrow.” “In sickness and health.” “Until death.” What would it look like this week to live as the person who made that promise?

Simon

That is powerful. And for single people?

James Porter

For single people, the application is to examine what kind of love you are preparing for. Are you looking mainly for someone who will produce feelings of excitement, affirmation, and fulfillment? Or are you becoming the kind of person who can make and keep wise promises? Covenant love is not only for married people. Christians practice promise-shaped love in friendship, family, church membership, service, and ordinary faithfulness.

Simon

That helps. Because this series is for single people too. A single person can ask: Am I learning to love people when it costs me? Am I faithful to commitments? Do I leave relationships, churches, friendships, or responsibilities the moment they stop feeling rewarding?

James Porter

Yes. A fourth practice is to pay attention to how you narrate your feelings. When feelings fade, do you immediately say, “Something is wrong”? Or can you say, “This may be a dry spell, and covenant love knows how to keep loving through dry spells”? That does not mean ignoring serious problems. But it does mean refusing to treat fluctuating emotions as ultimate truth.

Simon

That is so important. Feelings are real. But they are not always reliable guides.

James Porter

Exactly. A fifth practice is to speak the gospel to your heart. When love feels hard, remember: Christ did not wait until we were lovely. He loved us to make us lovely. Christ did not leave when love became costly. He stayed. Christ did not merely feel compassion. He acted. He gave Himself. Then ask: What would it look like to love in response to that love?

Simon

So again, the chapter does not end with sheer willpower. It ends with Christ.

James Porter

Yes. Christian covenant love is not powered by stubbornness alone. It is powered by the love of Christ received by faith and made real by the Spirit.

Simon

Let me add one more practice. For one week, look for one person you are tempted to treat according to your feelings, and instead do one concrete action of love. Maybe that is your spouse. Maybe it is your child. Maybe it is a friend. Maybe it is someone in your church. Maybe it is someone you do not naturally enjoy. Do the action of love. Listen. Serve. Encourage. Forgive. Make the call. Show up. Give time. Keep the promise. Not because your emotions are already aligned, but because love can lead the emotions.

James Porter

Yes. That is very much in the spirit of the chapter. Actions of love are not empty when they seek the good of the other. They are often the path by which the heart is reshaped.

Simon

So the practices this week are simple but searching: Identify where you treat relationships like a consumer. Restore one action of love you have withdrawn. Revisit the meaning of promise. Pay attention to how you narrate fading feelings. Speak the gospel to your heart. And practice one concrete action of love regardless of whether the feeling is strong. That is plenty to work with.

Simon

Alright… let’s slow this down and reflect a bit. We’re going to take these one at a time. If you’re listening alone, you might pause between them. If you’re with a group, let the silence do some work. Here’s the first question. How have you tended to define love? Do you think of love primarily as a feeling, a desire, a sense of chemistry, or emotional fulfillment? Or do you think of love primarily as self-giving action and covenant commitment? What has shaped your definition?

James Porter

That question matters because our definition of love will shape what we expect from marriage and relationships. If love is mainly feeling, then fading feelings will feel like failure. If love is covenant commitment, then fading feelings become a context where love must act faithfully.

Simon

Second question. When you hear someone say, “We do not need a piece of paper to love each other,” what assumptions about love and marriage are underneath that statement? And how does the biblical idea of covenant challenge those assumptions?

James Porter

The issue is not that paper itself is magical. The issue is whether love is willing to bind itself. Marriage-level love does not merely enjoy closeness. It gives itself through promise.

Simon

Third question. Where do you see consumer thinking in your relationships? Where are you tempted to measure a relationship by whether your needs are being met at an acceptable cost? Where do you withdraw love when you feel you are not getting enough in return?

James Porter

That is a hard but necessary question. Consumer love often feels reasonable because it sounds like fairness. But covenant love asks a deeper question: What does faithfulness require?

Simon

Fourth question. What do marriage vows actually promise? How is a vow different from saying, “I love you right now and want to be with you”? And why is a promise of future love so important when feelings change?

James Porter

A vow speaks to the future. It says, “I will be loving, faithful, and true even when circumstances and emotions shift.” That promise creates stability where deeper love can grow.

Simon

Fifth question. Think about the image of being tied to the mast. When have you experienced a season where feelings were loud but not wise? How can vows, commitments, Scripture, wise counsel, and prayer keep you steady until your mind clears?

James Porter

That question is practical for marriage, but also for all of life. We need anchors because our feelings, though real, are not always reliable captains.

Simon

Sixth question. How does the idea of promise as freedom challenge the modern idea that freedom means keeping your options open? Where have you seen commitment actually create deeper freedom, trust, stability, or joy?

James Porter

Promises limit some options, but they open others. Without promise, you may preserve flexibility. But you lose the freedom to build deep trust.

Simon

Seventh question. Keller says early romance often involves loving an idea or image of the person, while mature love means being fully known and truly loved. Where have you seen the difference between being admired from a distance and being loved up close? Why is being fully known and truly loved so powerful?

James Porter

That kind of love reflects something of God’s love for us. It exposes us, humbles us, frees us from pretense, and gives us strength.

Simon

Eighth question. What is one action of love you can do even when you do not feel strong affection? It may be listening, serving, apologizing, showing patience, giving encouragement, keeping a promise, or refusing to withdraw. What would love do, regardless of what you feel right now?

James Porter

That question gets to the daily heart of the chapter. Love is not fake when it acts without strong feeling. Often, that is where love becomes most real.

Simon

Ninth question. Where might you be vulnerable to the idea that a new romance, a new relationship, or a new thrill would solve your dissatisfaction? How does the chapter challenge the belief that fading feelings mean you need a new person rather than deeper covenant faithfulness?

James Porter

This is important because the early thrill can be very deceptive. A new relationship may seem to promise life, but the same pattern of fading will come again if love is built only on emotion.

Simon

Tenth question. How does the example of Christ reshape your understanding of love? Jesus did not love us because we were lovely. He loved us to make us lovely. He stayed. He gave Himself. He forgave. He acted for our good at great cost. How should that shape the way you love your spouse, future spouse, family, church, or friends?

James Porter

That is the foundation. Christian love is not merely inspired by Christ. It is patterned after Christ and empowered by Christ.

Simon

And finally, take some time to pray. Ask God to expose where you have accepted a shallow definition of love. Ask Him to free you from consumer thinking. Ask Him to strengthen your commitments. Ask Him to teach you how to act in love even when feelings are weak. And ask Him to make the love of Christ so real to you that you become more faithful, more tender, more truthful, and more willing to give yourself for the good of others.

James Porter

Yes. And pray with hope. The point is not to become mechanical. The point is to become more deeply loving. Covenant does not kill love. In Christ, covenant is the place where love grows up.

Simon

None of these questions are meant to overwhelm you. They are meant to slow you down. Because if we get love wrong, we get marriage wrong. And if we get covenant wrong, we will not know how to stay long enough for love to deepen. Take your time with them.

Simon

James, thank you. This chapter felt like it brought us right into the center of what marriage actually is. If I had to summarize today in one sentence, it would be this: The essence of marriage is covenant love — a binding promise of future faithfulness that gives romance the safety, time, and truth it needs to become deep love. That is very different from the way our culture often talks about love. Our culture says love is real when the feelings are strong. The Bible says love is real when it gives itself for the good of the other. Our culture says commitment may kill romance. The Bible says covenant is what helps romance grow into something deeper than excitement. Our culture says fading feelings may mean you chose wrong. The Bible says fading feelings may be the place where love must act, and by acting, become stronger. And at the center of all of it is Christ. He did not love us because we were lovely. He loved us to make us lovely. He did not leave when love became costly. He stayed. So as you head into this week, start simply. Ask yourself: Where am I treating love like a consumer? Where have I withdrawn actions of love because my feelings weakened? And what promise-shaped act of love can I practice this week? Not to fake love. Not to perform love. But to actually love. Because actions of love can train the heart. Next week, we’ll continue with The Mission of Marriage. We’ll look at what marriage is for — how husband and wife become spiritual friends, helping each other become the people God designed them to be. If today’s conversation was helpful, spend some time with the reflection questions — on your own or with others — and let them work on you slowly. And if you haven’t already, subscribe so you can keep walking with us. We’re grateful you’re here. We’ll talk again soon.
