1 Corinthians 6:12-20 - Avoid Sexual Immorality
12 All things are lawful for me, but all things are not expedient; all things are lawful, but I will not be brought under the power of any. 13 Food for the stomach, and the stomach for food; but God will destroy both it and them. And the body is not for fornication but for the Lord; and the Lord for the body; 14 and God both raised the Lord, and will raise us up by his power. 15 Know you not that your bodies are Christ's members? Shall I then take the members of Christ and make them a harlot's members? by no means. 16 Know you not that he who is joined to a harlot is one body [with her]? For the two, says he, shall be one flesh. 17 But he that is joined to the Lord is one spirit [with him].
18 Avoid fornication. Every crime that a man commits is out of his body; but he that commits fornication sins in his body. 19 Know you not that your bodies are a temple of the Holy Spirit in you which you have from God, and you are not your own? 20 For you are bought with a price; therefore glorify God in your body.
