1st Corinthians 6:15

12 "All things are lawful for me," but not all things are expedient. "All things are lawful for me," but I will not be brought under the power of anything.

13 "Foods for the belly, and the belly for foods," but God will bring to nothing both it and them. But the body is not for sexual immorality, but for the Lord; and the Lord for the body.

14 Now God raised up the Lord, and will also raise us up by his power.

15 Don`t you know that your bodies are members of Christ? Will I then take away the members of Christ, and make them members of a prostitute? Certainly not!

16 Or don`t you know that he who is joined to a prostitute is one body? For, "The two," says he, "will become one flesh."

17 But he who is joined to the Lord is one spirit.

18 Flee sexual immorality. "Every sin that a man does is outside the body," but he who commits sexual immorality sins against his own body.
