1 Corinthians 6:15-19

Don't you know your bodies are parts of Christ's body? Should I take the parts of Christ's body and join them to a prostitute? Absolutely not! Don't you realize that anyone who has sex with a prostitute becomes “one body” with her? Remember that Scripture says, “The two will become one body.” But whoever is joined to the Lord is one with him in spirit! Stay away from sexual immorality! All other sins that people commit are outside of the body, but sexual immorality is a sin against your own body. Don't you know that your body is a temple of the Holy Spirit that is within you, that you received from God?
