1 Corinthians 6:15-20

15Do you not know that your bodies are members of Christ himself? Shall I then take the members of Christ and unite them with a prostitute? Never! 16Do you not know that he who unites himself with a prostitute is one with her in body? For it is said, “The two will become one flesh.” Gen. 2:24

17But whoever is united with the Lord is one with him in spirit. Or in the Spirit 18Flee from sexual immorality. All other sins a person commits are outside the body, but whoever sins sexually, sins against their own body. 19Do you not know that your bodies are temples of the Holy Spirit, who is in you, whom you have received from God? You are not your own; 20you were bought at a price. Therefore honor God with your bodies.
