1 Corinthians 6:15-20

Know ye not that your bodies are members of Christ? shall I then take away the members of Christ, and make them members of a harlot? God forbid. Or know ye not that he that is joined to a harlot is one body? for, The twain, saith he, shall become one flesh. But he that is joined unto the Lord is one spirit. Flee fornication. Every sin that a man doeth is without the body; but he that committeth fornication sinneth against his own body. Or know ye not that your body is a temple of the Holy Ghost which is in you, which ye have from God? and ye are not your own; for ye were bought with a price: glorify God therefore in your body.
