1 Corinthians 6:18-20

Flee from sexual immorality! Every other sin that we do is outside the body, but sexual immorality is a sin against your own body. Do you not know that your body is a temple of the HOLY SPIRIT, which is in you, whom you received from GOD? You are not your own, for you have been bought with a price. Therefore, glorify GOD in your body and in your spirit, which belong to GOD.
