1 Corinthians 6:13-18
6:13 “Food is for the stomach and the stomach is for food, but God will do away with both.” The body is not for sexual immorality, but for the Lord, and the Lord for the body.
6:14 Now God indeed raised the Lord and he will raise us by his power.
6:15 Do you not know that your bodies are members of Christ? Should I take the members of Christ and make them members of a prostitute? Never!
6:16 Or do you not know that anyone who is united with a prostitute is one body with her? For it is said, “The two will become one flesh.”
6:17 But the one united with the Lord is one spirit with him.
6:18 Flee sexual immorality! “Every sin a person commits is outside of the body” – but the immoral person sins against his own body.
