1 Corinthians 6:16-20

Don’t you know that anyone joined to a prostitute is one body with her? For Scripture says, The two will become one flesh. But anyone joined to the Lord is one spirit with him. Flee sexual immorality! Every other sin a person commits is outside the body, but the person who is sexually immoral sins against his own body. Don’t you know that your body is a temple of the Holy Spirit who is in you, whom you have from God? You are not your own, for you were bought at a price. So glorify God with your body.
