Upside Down Kingdom: Serious Business

Kingdom Righteousness Goes Deeper Than You Think: What Jesus Really Said About Lust, Adultery, and Divorce

Most of us spend more time asking how close we can get to sin than how close we can get to Jesus. In Matthew 5:27-32, Jesus cuts through that mindset entirely and goes straight to the heart. This passage is uncomfortable, but it is one we absolutely have to encounter honestly.

What Is the Bottom Line Jesus Is Making in Matthew 5:27-32?

Before diving into the details, here is the core truth worth holding onto from this passage:

Kingdom people do not negotiate with sinful desire. We put it to death because people are image bearers, not objects.

That single statement shapes everything Jesus says in this section of the Sermon on the Mount.

Is Lust Just About Sex? What Jesus Actually Means

It is easy to reduce lust to one narrow category and think it only applies to certain people or certain situations. But lust is far more than most of us think.

Jesus says in Matthew 5:27-28:

"You have heard that it was said, Do not commit adultery. But I tell you, everyone who looks at a woman lustfully has already committed adultery with her in his heart." - Matthew 5:27-28 Christian Standard Bible (CSB)

Jesus is not rewriting the commandment. He is attacking our interpretation of it. Just as He showed that murder begins in the heart with anger, here He shows that adultery begins in the heart long before any physical act takes place.

What Is the Biblical Definition of Lust?

Lust is not the same as sexual desire. God created sexual desire and called it good. Lust is what happens when that desire gets twisted inward and people become objects for our consumption rather than image bearers made in the likeness of God.

A working definition: Lust is reducing someone made in God's image into something for my consumption.

The moment we begin asking "what can I get from this person?" instead of "who is this person?", we are living in the mindset Jesus is directly rebuking here. Whether it shows up through pornography, emotional affairs, fantasy, social media, or entertainment choices, lust always points us away from what God intended.

A Question Worth Asking This Week

As you go through your week, ask yourself honestly: Am I seeing an image bearer or an object? One reflects the kingdom of God. The other reflects the fallen desires of our hearts.

Why Does Jesus Talk About Gouging Out Your Eye and Cutting Off Your Hand?

Jesus does not shift to a lesson on anatomy in verses 29-30. He is declaring war on sin.

"If your right eye causes you to sin, gouge it out and throw it away. For it's better that you lose one of the parts of your body than for your whole body to be thrown into hell. And if your right hand causes you to sin, cut it off and throw it away. For it's better that you lose one of the parts of your body than for your whole body to go into hell." - Matthew 5:29-30 Christian Standard Bible (CSB)

To be clear, Jesus is not prescribing self-harm. He is prescribing ruthless repentance where nothing stands in the way of following God by the power of His Spirit.

Sin Is More Dangerous Than You Think

We all have a tendency to coddle our own sin. We minimize it, keep it in a box, and tell ourselves it is not that bad. But Jesus makes the stakes plain. Small compromises rarely stay small. Sin always asks for more than it initially promises.

The hard truth is this: no one ever drifts into holiness. People drift into sin. Holiness requires intention.

Jesus is not asking us to white-knuckle our way to purity. The same Savior who commands us to kill sin gives us His Spirit to fight it. But the question He is asking is not "how much sin can I keep?" It is "what needs to die so I can follow Jesus faithfully?"

Practical Steps for Fighting Lust

• Delete the app that feeds the sin
• Install accountability with someone you trust
• End a relationship kept in secret
• Confess what has been hidden and change your routine

None of these things save you. Only Jesus saves. But our actions are proof of a heart that has been changed by God's grace.

Ask yourself this week: Am I feeding my sin or starving it?

What Does Jesus Say About Divorce and Why Does It Belong Here?

At first glance, the shift to divorce in verses 31-32 seems like a change of subject. It is not. Jesus is still addressing the exact same heart issue.

"It was also said, Whoever divorces his wife must give her a written notice of divorce. But I tell you, everyone who divorces his wife, except in a case of sexual immorality, causes her to commit adultery. And whoever marries a divorced woman commits adultery." - Matthew 5:31-32 Christian Standard Bible (CSB)

Why Is Jesus Bringing Up Divorce After Talking About Lust?

Because the heart problem is the same. Lust says "I want you for what you can give me." Divorce, as it was being practiced in Jesus' day, often said "I don't want you anymore because you've stopped giving me what I want." Both reveal a consumer approach to people rather than covenant faithfulness.

In Jesus' day, some religious teachers had twisted the provision in Deuteronomy 24 into permission to divorce a wife for nearly any reason. Jesus wades directly into that cultural debate and exposes the deeper issue. It was not merely about divorce. It was about a heart that views people as disposable.

What About the Exception Jesus Mentions?

Jesus does give an exception for sexual immorality. The word He uses, porneia, refers broadly to sexual immorality. His point is that this kind of unfaithfulness has already broken the covenant. The exception does not make divorce mandatory. It acknowledges that covenant-breaking behavior has already done serious damage.

A Word to Anyone Carrying the Weight of Divorce

This passage is not a weapon to beat anyone with. Jesus offers grace no matter where we are or what we have been through. The same Jesus who speaks truth about covenant faithfulness is the same Savior who offers healing, forgiveness, and restoration to those carrying the scars of broken marriages.

The Common Thread Between Lust and Divorce

A heart that consumes eventually abandons. Lust trains us to evaluate people by what they provide. Left unchecked, that mindset does not stay in fantasy. It shows up in our marriages, our friendships, and how we treat the people around us every day.

Ask yourself this week: Am I consuming people or loving them faithfully?

What Does This Mean for How We Treat People Every Day?

The image bearer principle does not only apply to sexuality. It shapes how we talk about people, how we treat coworkers, how we speak to our spouses, and what our children learn from watching us.

What are your children learning from how you talk about others? How are they learning to treat neighbors, coworkers, and people they disagree with?

The kingdom of God does not exist to consume people. It exists to love them faithfully, the way we have been loved by God.

How Does the Gospel Connect to All of This?

Jesus never treated people as objects. He never used anyone. He laid down His life for us while we were still sinners. While we were unfaithful, He was steadfast. While we broke the covenant, He kept it all the way to the cross.

That is why kingdom people cannot simply manage sin. We make war against it. Not to earn God's love, but because we recognize how deeply we have already been loved.

The good news of the gospel is that Jesus did not just die to forgive our sinful actions. He died and rose again to give us new hearts. And that is exactly what this passage is ultimately pointing toward. Not behavioral management, but heart transformation.

Life Application

This week, identify one specific area where you have been negotiating with sin rather than putting it to death. It might be something you look at, something you entertain in your mind, or a relationship you have kept hidden. Choose one concrete, visible act of repentance and take it this week. Delete it, confess it, end it, or bring it into the light with someone you trust. Do not wait for a better moment. The best time to obey Jesus was yesterday. The second best time is right now.

Ask yourself these questions as you reflect:

• Am I seeing the people around me as image bearers made in God's likeness, or as objects that exist to meet my needs?
• Am I feeding my sin or starving it? What specific habit or choice is feeding it right now?
• What visible act of repentance do I need to take today, not someday, but today?
• Am I asking how close I can get to sin, or how close I can get to Jesus?

Kingdom righteousness always goes deeper than behavior and straight to the heart. And the King who demands that transformation is the same One who makes it possible.
