1 Corinthians 6:15-19

Don't you know that your bodies are part of the body of Christ? Is it right for me to join part of the body of Christ to a prostitute? No, it isn't! Don't you know that a man who does that becomes part of her body? The Scriptures say, “The two of them will be like one person.” But anyone who is joined to the Lord is one in spirit with him. Don't be immoral in matters of sex. That is a sin against your own body in a way no other sin is. You surely know that your body is a temple where the Holy Spirit lives. The Spirit is in you and is a gift from God. You are no longer your own.
