1 Corinthians 6:15-20

15Do you not know that your bodies are members of Christ? Shall I then take the members of Christ and unite them with a prostitute? Never! 16Or don’t you 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.”1 17But he who unites himself with the Lord is one with Him in spirit.

18Flee from sexual immorality. Every other sin a man can commit is outside his body, but he who sins sexually sins against his own body. 19Do you not know that your body is a temple 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 glorify God with your body.2
