The Wrong Kind of Oneness - Greg Laurie Devotion - May 18, 2026

Audio By Carbonatix

“Don’t you realize that your bodies are actually parts of Christ? Should a man take his body, which is part of Christ, and join it to a prostitute? Never! And don’t you realize that if a man joins himself to a prostitute, he becomes one body with her? For the Scriptures say, ‘The two are united into one.’” (1 Corinthians 6:15–16 nlt)

In this week’s devotions, we’re going to focus on passages from the apostle Paul’s first letter to the believers in Corinth. And we’re going to start with his words of wisdom to married couples in 1 Corinthians 6.

Can you imagine what our culture would be like if we obeyed the single commandment, “You must not commit adultery” (Exodus 20:14 nlt)? Can you imagine how different our world would be? How many divorces would have been avoided? How many families would still be together? How many fathers would be home to raise their children?

Many social ills can be traced to the breakdown of the family and specifically to the absence of the father in the home. And often marriages fall apart because of the sin of adultery—that is, sex with someone besides your spouse.

God established marriage as a union and oneness between a man and a woman. Sex is not some toy that we play with to satisfy our desires. The Bible says, “Give honor to marriage, and remain faithful to one another in marriage. God will surely judge people who are immoral and those who commit adultery” (Hebrews 13:4 nlt).

Yet that warning often falls on deaf ears. Some people try to excuse adultery by arguing that anything that happens between two consenting adults is okay. Or by pointing out that spouses aren’t always sexually compatible, which makes it necessary to go outside the marriage. Or by claiming that if no one else ever finds out, it’s a victimless crime.

But the biblical reality is that when a man and a woman come together sexually, a oneness takes place. We are told in 1 Corinthians 6:15–16, “Don’t you realize that your bodies are actually parts of Christ? Should a man take his body, which is part of Christ, and join it to a prostitute? Never! And don’t you realize that if a man joins himself to a prostitute, he becomes one body with her? For the Scriptures say, ‘The two are united into one’” (nlt).

Jesus identified the roots of adultery in His Sermon on the Mount. “You have heard the commandment that says, ‘You must not commit adultery.’ But I say, anyone who even looks at a woman with lust has already committed adultery with her in his heart. So if your eye—even your good eye—causes you to lust, gouge it out and throw it away. It is better for you to lose one part of your body than for your whole body to be thrown into hell” (Matthew 5:27–29 nlt).

Lust, left unchecked, can lead to adultery. That’s why it’s important to separate ourselves from people, scenarios, and settings that can trigger lust. As Jesus points out, no sacrifice is too great to preserve the unity of marriage.

Reflection question: What practical steps can reduce the risk of adultery in a marriage?
