When Desire Craves

BY DESIRE

Sin is not merely a failure to behave rightly, but the result of selfish desire replacing submission to God's design. This series explores how desire shapes decision-making, distorts God's good gifts, and how spiritual maturity requires learning to submit our desires to God so that He receives the glory.

Remember:

Sin begins when desire becomes selfish.

When you submit to your design instead of your desire, God receives the glory.

(3) When Desire Craves

Verse: Genesis 1:26–28; 2:18–25; Matthew 5:27–32 (cf. Romans 1:24–27; James 4:4)

Big Idea: This lesson explores marriage, sexuality, and relationships as good gifts distorted when desire seeks fulfillment outside of God's design. The class asks whether love is defined by personal fulfillment or covenantal faithfulness. This week highlights how desire often attempts to rewrite God's relational boundaries for selfish ends.

Where We’ve Been

Last week we looked at anger — how an unmet or misdirected desire produces not just violence, but malice, contempt, and relational destruction long before any action occurs.

We saw that God cares about the little things, that the anger you sit with quietly is already moving… is sinful.

And we landed on this: you are not an animal that is a slave to your desires. You are an image-bearer, and by the Holy Spirit you have the power to do something about what you feel before it becomes what you do. And to make it right.

Where We’re Going

This week we're going to talk about something that might feel a little uncomfortable, but it's too important to skip.

We're going to look at lust, sexuality, and relationships, not only to make you feel guilty, but to help you understand what God actually designed these things for, and why this happens when desire pulls us away from that design.

Introductory Questions

God designed us for relationship.

Not just romantic… we’ve talked about this a great deal in Bible classes before.

That desire to be close to someone, to be loved, to be chosen, that is not the problem. That is image-bearer stuff. God wired us for it.

Q | So if that desire itself is good, what makes it go wrong? How/why do people mess it up?

Last week, we thought about anger. Easy enough to visualize and understand.

When you act by your desire in anger, you devalue someone else as a created-in-the-image-of-God person. Not just with murder, but words and thoughts too.

Lust is really similar. If anger is distortion towards others, lust is distortion towards yourself.

When you act by your desire in lust, you devalue your self as a created-in-the-image-of-God person.

Yes, this category of sin has harmful effects on other people.

But, when desire is driving, you stop thinking clearly, not just about the other person, but about yourself. By the time lust is in control, you've already forgotten who you are. 

Before we move on and hear from Jesus, does that make sense?

Getting Into The Text(s)

Read Matthew 5:27-32.

Jesus doesn't just address the act of adultery, which was/IS a major concern, He goes straight to the heart.

Lust isn't a lesser version of sexual immorality. It is sexual immorality, happening before anything physical ever occurs.

Jesus uses this phrase lustful intent. Think about sin like a line that is crossed…

Q | What does that tell us about where sin actually begins? Think backwards, when is the line crossed for anger?

Jesus links these two sins together, anger/murder and lust/adultery. Sin does start at the action, it starts when you allow selfish desire to control your heart.

Jesus says if your eye causes you to sin, gouge it out. If your hand causes you to sin, cut it off. He's not being literal, He's being urgent.

The point is: do whatever it takes. Do not negotiate with lust. Do not sit with it and see where it goes. Flee.

Q | Why do you think Jesus uses such extreme language here? What is he trying to get across?

Jesus uses similar extreme language regarding anger. Remember, to use hateful words is deserving of the fires of Hell.

The same is true with lust: God cares about the little things.

You might think, “It’s not that big a deal… it’s not like it’s hurting anybody.”

That just isn’t true… but that’s how you can trick yourself, when you’re acting by desire.

There’s another place I really like to go when thinking about this idea. And it’s the parable of the Prodigal Son. (Luke 15:11-32)

Q | Help me recall that parable. What happens? What’s going on?

Wait… what does that have to do with lust?

There’s an image, right in the middle of this parable, that perfectly captures this idea Jesus is talking about.

The son goes off into the world to follow after his own desires. And when he comes up empty, Luke 15:16 says he was longing to be fed with the pods that the pigs ate, and no one gave him anything.

What an un-human moment for someone who had a home, a family, an inheritance…

That word — lustful intent in Matthew 5 — is the same word Jesus uses in the parable of the prodigal son. And it captures the image perfectly.

Remember: When you act by your desire in lust, you devalue your self as a created-in-the-image-of-God person.

When your desire is straining after things that aren’t from God, you will wind up empty. And settle for things, among the pigs.

“It’s not that big a deal… it’s not like it’s hurting anybody.” Are you sure about that?

Q | In this parable, who is hurting right now because of the life the son is living?

That's what lust does. It doesn't start with the pigpen. It starts with hunger, a desire: a real, legitimate desire to be loved, to be close, to belong. But when that desire goes unsubmitted to God, it leads you somewhere you never intended to go. And by the time you're there, you're not thinking about the pigs. You're not thinking about the father or the people who love you. You're just hungry, and desperate, and willing to go wherever that hunger leads.

Not a question I want you to answer out: Has there ever been a time — not necessarily just with lust, but with any desire — where you wanted something so badly that you stopped thinking clearly about who you were or what you knew was right?

Lust doesn't feel like self-degradation in the moment. It feels like need. It feels like longing. That's why the prodigal doesn't realize what he's become until he's already in the pigpen. The next verse says, “When he came to,” he longed to go back and be with his father.

This is a really great time for me to tell you, and this is the most important thing I’ll tell you tonight: talk to your parents. I know, just by saying that, some of you are rolling your eyes.

If you really feel like you can’t talk to your parents yet about these issues, find a God-honoring adult that you can.

But I promise you, so much hurt, to myself and to people I loved, could have been avoided if I had just talked to my parents.

Discussion / Breakouts

Lust, or selfish romantic desire leads to a manner of different sins. But the way to think about it is to focus on what God designed for good:

God designed romantic sexual relationships to be between one man and one woman, and to be for life.

Anything outside of that is sin. From the very small to the very big. That’s what Jesus says.

Q | How do you recognize lust before it becomes something you act on? What does it feel like early?

We are not animals that are slaves to our desires. We are image-bearers and co-creators with God, and by the Holy Spirit we actually have the power to do something with what we feel before it becomes what we do.

Sin begins when desire becomes selfish. When romantic longing is about what I want, what I crave, what I need — it has consumed by lust and drifting away from design.

Let’s be practical together…

Q | When you feel lust building, what can be done to give that to God?

The space between feeling and acting is the danger zone.

When you're in the danger zone, when desire is building and you feel it pulling:

Prayer first, not last. What if the first thing you did when desire stirred was ask God for what you actually want instead of going after it yourself? James says you don't have because you don't ask. Ask.

Slow the progression down. The problem is rarely the first moment of desire. It's what happens when you sit with it. The Bible says flee. Cut it off. Go away. Build habits that create distance between the feeling and the action.

Ask what's underneath. Lust is almost always covering something else. Ask yourself — what do I actually want here? That question, brought honestly to God, interrupts the progression before it becomes sin.

Q | What about after the fact… what do you do if you’ve already sinned?

Because of Jesus, even when we live by desire and sin, we can be restored.

The gospel isn't just forgiveness in the abstract — it's the power to actually go back, make it right, and be changed. That's image-bearer language, not just behavior modification.

Desires that are genuinely good but get distorted by lust:

These aren’t sinful. All of them are good. But unsubmitted, they become something that hurts you and the people around you.

To be loved and accepted. Romantic and sexual attention can feel like proof that you are wanted, that you matter, that someone chose you. That desire to be chosen is not evil. Unsubmitted, it becomes something you pursue in ways that reduce you to less than what God made you to be.

To be known and understood. Real intimacy is the desire to be fully seen and still loved. Lust short-circuits that. It offers the feeling of closeness without the vulnerability of actually being known.

To feel valuable and desirable. Some of this isn't even about another person — it's about wanting to feel worth wanting. That's not sinful. It becomes sinful when it's pursued through lust or sexual attention rather than submitted to God.

To experience pleasure and joy. God designed us for pleasure. That is not the problem. The problem is seeking it in ways that reduce yourself or another person to an instrument rather than an image-bearer.

To feel safe and close to someone. Some sexual sin isn't primarily about desire at all — it's about wanting to feel close, to feel secure. That desire for closeness is good. Outside of God's design it becomes something that hurts rather than heals.

Conclusion

Acting sinfully in anger means de-valuing another, forgetting they are made in the image of God. Acting sinfully in lust means de-valuing yourself, forgetting that you are made in the image of God.

You are not an animal that is a slave to your desires. You are a co-creator, made in the image of God, and by the Holy Spirit you have the power to do something about what you feel before it becomes what you do.

David — a man after God's own heart — fell into lust, and it led him somewhere devastating. Adultery. Betrayal. Murder. And yet he is still called a man after God's own heart. Not because what he did didn't matter, but because he repented. He turned back. No amount of lust or sexual immorality is too great for repentance and the forgiveness of God.

Sin begins when desire becomes selfish.

When you submit to your design instead of your desire, God receives the glory.
