Matthew 5:27-32 — Lust & Divorce

FRANK: Jesus says you can commit adultery without ever touching another person.

LINDA: That is a genuinely uncomfortable sentence to open a show with, Frank.

FRANK: It is meant to be uncomfortable. That is the whole force of what he says in the Sermon on the Mount, and today we are sitting in Matthew chapter five, verses twenty-seven through thirty-two. Welcome to Dig Deeper, by the way, glad you are here for this one, because it is a hard passage and I think an easy one to get wrong.

LINDA: Hard is right. And I will be honest, this is one of those passages where a lot of people just quietly close the Bible and go make a sandwich. Pluck out your eye. Cut off your hand. Where do we even start?

FRANK: We start by reading it, all of it, so we feel the whole weight before we take anything apart.

LINDA: Go ahead, read it to us.

FRANK: "You have heard that it was said, 'You shall not commit adultery;' but I tell you that everyone who gazes at a woman to lust after her has committed adultery with her already in his heart. If your right eye causes you to stumble, pluck it out and throw it away from you. For it is more profitable for you that one of your members should perish than for your whole body to be cast into Gehenna. If your right hand causes you to stumble, cut it off, and throw it away from you. For it is more profitable for you that one of your members should perish, than for your whole body to be cast into Gehenna. It was also said, 'Whoever shall put away his wife, let him give her a writing of divorce,' but I tell you that whoever puts away his wife, except for the cause of sexual immorality, makes her an adulteress; and whoever marries her when she is put away commits adultery."

LINDA: The look. That is what I keep snagging on. He puts everything in the look, before anybody has done anything. Sell me on why that is not just Jesus being impossibly strict for the sake of it.

FRANK: Because he is not adding a new rule. He is exposing an old one. Remember the formula we talked about back on day five, "you have heard it said, but I tell you." People hear that and they assume Jesus is raising the bar, making the law harder than Moses made it. He is not. He is reading the law the way it was always meant to be read. The seventh commandment, Exodus twenty verse fourteen, "you shall not commit adultery." One line. And the whole assumption of the religious world in his day was that as long as your body stayed clean, you had kept it. Jesus says no. That commandment was never about the body only. It always reached back into the wanting. Is Jesus inventing a new standard, or uncovering what was always there?

LINDA: So he is not inventing the standard. He is uncovering it. But where did it come from in the first place?

FRANK: Exactly that, and here is where it gets interesting, because he did not invent it and neither did the rabbis of his day. Go back to Job, chapter thirty-one verse one. Job says, "I made a covenant with my eyes, how then should I look lustfully at a young woman?" That is centuries before the Sermon on the Mount. A righteous man under the old covenant already understood that the lingering look was where the sin was born. Not a harmless little glance that might, someday, if you were unlucky, lead somewhere. The look itself was the beginning of it. Job knew that. He made a covenant, a binding agreement, with his own eyes. But here is where the objection comes in.

LINDA: A look happens in half a second. You cannot help what walks past you on the street. Are you telling me a person is guilty for a thing that fast and that involuntary?

FRANK: Watch the word he uses, though. He does not say the man who sees a woman. He says the man who gazes at a woman to lust after her. That little phrase, "to lust after her," is doing enormous work. This is not the involuntary glance. This is the second look. The one you choose. The gaze that lingers and then goes to work in the imagination, that starts building something. Jesus is not condemning your eyes for functioning. He is naming the moment the will gets involved, the moment you take what you saw and you feed it.

LINDA: The moment I feed it. That is a different thing than getting caught off guard.

FRANK: Completely different, and Scripture maps that exact sequence for us more than once. Think of the very first sin, Genesis three. "The woman saw that the tree was good for food, and that it was a delight to the eyes, and that the tree was to be desired." Seeing, desiring, then taking. That is the whole anatomy of the fall right there, and Jesus is pointing at the same three steps. James says it too, chapter one. "Each one is tempted when he is drawn away by his own lust and enticed. Then the lust, when it has conceived, bears sin; and the sin, when it is full grown, produces death." James treats the desire like a pregnancy. It conceives, it grows, it delivers. Nothing about that is private and harmless. It is a thing that is going somewhere.

LINDA: And what it delivers is death. That is not the word I would have reached for.

FRANK: Most of us file the internal stuff under "not that big a deal, nobody got hurt." James will not let us. Neither will Jesus. Which is exactly why the next thing out of his mouth is so violent.

LINDA: The eye and the hand. Pluck it out, cut it off. I have to ask the obvious thing, because someone listening is genuinely wondering. Does he mean it literally?

FRANK: No, and here is how we know for certain. A blind man can still lust. A man with no hands can still covet. If the problem lived in the eye, then removing the eye would fix it, and Jesus knew perfectly well it would not. He is not giving surgical instructions. He is telling you how far you should be willing to go in the fight, and he is telling you where the disease actually lives. Not in the body part. In the heart behind it. The eye is just the doorway. Then why the graphic language at all?

LINDA: Because "take it seriously" has never made anybody take anything seriously?

FRANK: Because "take it seriously" is exactly the phrase that has never once made anybody take anything seriously. The verbs are meant to hurt. Pluck out. Cut off. Throw it away from you. That is amputation language, and he chose it because he is describing a matter of life and death. Listen to the reason he gives. "It is more profitable for you that one of your members should perish than for your whole body to be cast into Gehenna." And that word, Gehenna, is not a vague poetic word for the afterlife. It was a real place. A ravine outside Jerusalem, the Valley of Hinnom, where in Israel's darkest days children were burned in sacrifice, and which later became the smoldering garbage dump of the city. Fire that never quite went out. When Jesus said Gehenna, his listeners did not think of an abstraction. They saw a specific valley, and they smelled the smoke.

LINDA: So he is standing there pointing at an actual burning valley they could all picture, and saying, your sin is carrying you toward that.

FRANK: Violence against whatever is carrying you—that is the picture. The only sane response is what the old pastors called mortification, putting sin to death. John Owen, writing in the sixteen hundreds, put it about as bluntly as it can be put. Be killing sin, or it will be killing you. There is no third option, no quiet truce where you and the sin just agree to live in the same house. A sin you tolerate is a sin gaining ground. And Paul says the same thing to the church later, Colossians three, "put to death sexual immorality, uncleanness, depraved passion, evil desire." Same violence. Now aimed not at the literal hand but at the appetite the hand serves.

LINDA: Can I stop you there, because this is the part that would honestly wreck me if we left it here. If the standard is a heart that does not even want the wrong thing, that never lingers, never feeds it, then I am not standing anywhere. Nobody is. I fail this by lunchtime.

FRANK: Nobody is standing. And Linda, that is not the accident of the passage. That is the design of it.

LINDA: Say more, because it sounds like you just agreed my situation is hopeless. Is there a way out of this?

FRANK: It is hopeless, if the plan was to save yourself with a clean record. Hear what Jesus is actually doing. He draws the standard up to its true, terrible height. Not adultery avoided. A heart that does not covet at all. And he draws it up there precisely so that you will stop trusting your own tidy behavior and start trusting him. Because there is one man who kept this word completely. Whose eye never once wandered. Whose heart was pure through and through. And that spotless obedience, the thing you and I cannot produce on our best day, he offers to sinners. The severity here is mercy wearing a hard face. It refuses to let you rest in anything less than Christ himself.

LINDA: So the impossibly high bar is not there to crush me. It is there to move me off my own record and onto his. But how does that connect back to what he just said about cutting off sin?

FRANK: The gospel logic of the whole Sermon on the Mount lands right here. The same one who tells you to cut off sin, who points at that burning valley, went and endured the true Gehenna himself. Forsaken on the cross. Cut off, so that you never will be. The command to wage war on your sin is only ever spoken to people he has already decided to save. You fight as a rescued person, not a drowning one.

LINDA: That reframes the whole amputation thing. It is not the price of getting in. It is what a rescued person does.

FRANK: It is the fruit of the rescue, never the fee for it. Matthew Henry says it beautifully. "There is tender mercy under all the Divine requirements, and the grace and consolations of the Spirit will enable us to attend to them." Tender mercy under the requirement. Even here. Even in the plucking and the cutting.

LINDA: And that raises the last piece, because he pivots straight into divorce, which feels like a hard left turn. What is that doing right after all of this?

FRANK: It is not a left turn at all, it is the same argument. A husband in the first century could end a marriage with one piece of paper. He wrote a certificate, handed it to his wife, done. And there was a live fight among the rabbis over how easily he could do that. One school read Deuteronomy narrowly, divorce only for sexual sin. The other read it so broadly that a man could dismiss his wife for burning his dinner, or for a man simply finding another woman prettier. And in practice, that looser reading won the day.

LINDA: So a woman could be sent home over a ruined meal.

FRANK: Over a ruined meal. And here is what you have to feel to understand why Jesus reacts the way he does. That certificate started as a mercy, a real protection, giving a woman legal standing instead of leaving her at a man's word. But that mercy had been twisted into a license. And picture what waited for the woman who received it. She had almost no independent footing. She could not readily own property, could not enter most trades, could not rent a room and support herself. Her security ran through men, her father, then her husband. Take away the husband, and the floor simply dropped out from under her. She went back to her father's house if she could. If her father was dead, if her brothers would not have her, her options narrowed to remarriage, or charity, or worse.

LINDA: When Jesus says the man "makes her an adulteress," he is not scoring some technicality against her.

FRANK: He is exposing what the careless divorce actually does to a real woman. He is not blaming her. He is pushing the guilt back onto the man who signed the paper, the man whose hard heart reached for it. Dismissed for a fading face, she gets shoved toward a second marriage she never chose, and he carries that burden. Read that way, this stops being a cold rule about marriage law and becomes Christ's defense of the defenseless. He wrote his mercy into the exact place that world was cruelest.

LINDA: And when he limits it to sexual immorality, he is not just picking the stricter rabbi's side of the debate.

FRANK: No, he reaches back behind the whole argument. Later, in Matthew nineteen, he says it out loud, Moses permitted this "because of the hardness of your hearts, but from the beginning it has not been so." He is not adjudicating a scholarly dispute. He is going back past Moses to God's original design and restoring what marriage was always meant to be. Permanent. A covenant, not a contract you can void when the mood turns.

LINDA: Which ties it right back to the heart, doesn't it. The paper could dissolve the marriage. It could never soften the heart that reached for it.

FRANK: That is the thread throughout. The look. The paper. Both of them are the heart doing its quiet work where nobody sees. And that is the whole point of where Jesus aims. Not your reputation, which can stay spotless for years while something rots underneath. Your heart. The room nobody else gets to walk into.

LINDA: Which is exactly why this is so hard to actually do something about. If it is all internal, it can run for years and nobody knows.

FRANK: So the obedience this passage asks for is usually the opposite of hidden. It is honesty. Naming the specific doorway, the actual thing that keeps catching you, and putting a real obstacle in front of it today. Not tomorrow. If it is the phone after the house goes quiet, the charger moves to the kitchen tonight. That is "pluck it out" in the only form most of us will ever live it. And for some people it goes further, to saying the true sentence out loud to one person who knows you. Not a vague "I've been struggling," but the real words. That is expensive, because the price of it is your image, letting someone see you as less than they thought.

LINDA: And that is the part I would want to run from. Confession feels more dangerous than just white-knuckling it in private.

FRANK: It feels safer to stay hidden, yes. But hear why you can afford to be honest. You do not confess in order to earn his welcome. You already have it. He knew the whole of you, every gaze, every hidden thing, before you said a single word, and he went to the cross anyway. Because he was fully exposed and not cast out, you can be exposed and stay held.

LINDA: Held. That is the word I want to leave sitting on.

FRANK: Held is the right word. So hold that next to your week. The bar in this passage is impossibly high, on purpose, and whoever set it that high is the same one who met it for you and now stands beside you in the fight.

LINDA: And here is a small, concrete way to end that is not about you at all. Somewhere in your circle is a couple whose marriage is straining, worn thin. Pray for them tonight. By name. That God would guard what feels fragile. Let that be the first thing your honesty does, aim it outward at someone who needs it.

FRANK: A good charge. Pray for that marriage tonight.
