1 Corinthians 6
15 Ref Do you not see that your bodies are part of the body of Christ? how then may I take what is a part of the body of Christ and make it a part of the body of a loose woman? such a thing may not be.
16 Ref Or do you not see that he who is joined to a loose woman is one body with her? for God has said, The two of them will become one flesh.
17 Ref But he who is united to the Lord is one spirit.
18 Ref Keep away from the desires of the flesh. Every sin which a man does is outside of the body; but he who goes after the desires of the flesh does evil to his body.
