1 Corinthians 6:16-20

Or do you not know that the one who joins himself to a prostitute is one body with her? For He says, “The two shall become one flesh.”

But the one who joins himself to the Lord is one spirit with Him.

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

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

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