"But he who unites himself with the Lord is one with Him in spirit. Flee from sexual immorality. Every other sin a man can commit is outside his body, but he who sins sexually sins against his own body. 19Do you not know that your body is a temple of the Holy Spirit who is in you, whom you have received from God? You are not your own; 20you were bought at a price. Therefore glorify God with your body." 

1 Corinthians 6:17-20
