I Corinthians 6:12-17

All things are lawful for me, but all things are not helpful. All things are lawful for me, but I will not be brought under the power of any. Foods for the stomach and the stomach for foods, but God will destroy both it and them. Now the body is not for sexual immorality but for the Lord, and the Lord for the body. And God both raised up the Lord and will also raise us up by His power. Do you not know that your bodies are members of Christ? Shall I then take the members of Christ and make them members of a harlot? Certainly not! Or do you not know that he who is joined to a harlot is one body with her? For “the two,” He says, “shall become one flesh.” But he who is joined to the Lord is one spirit with Him.
