1 Corinthians 6:18, 19, 20

Flee immorality. Every other sin that a man commits is outside the body, but the immoral man sins against his own body.

Or do you not know that your body is a temple of the Holy Spirit who is in you, whom you have from God, and that you are not your own?

For you have been bought with a price: therefore glorify God in your body.
