1 Corinthians 6:15-20

15Know ye not that your bodies are the members of Christ? shall I then take the members of Christ, and make them the members of an harlot? By no means. 16What? know ye not that he who is joined to an harlot is one body? for two, saith he, shall be one flesh. 17But he that is joined to the Lord is one spirit. 18Flee immorality. Every sin that a man doeth is outside the body; but he that committeth immorality sinneth against his own body. 19What? know ye not that your body is the temple of the Holy Spirit who is in you, which ye have from God, and ye are not your own? 20For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God’s.
