12 I am free to do all things; but not all things are wise. I am free to do all things; but I will not let myself come under the power of any. 13 Food is for the stomach and the stomach for food, and God will put an end to them together. But the body is not for the desires of the flesh, but for the Lord; and the Lord for the body: 14 And God who made the Lord Jesus come back from the dead will do the same for us by his power. 15 Do you not see that your bodies are part of the body of Christ? how then may I take what is a part of the body of Christ and make it a part of the body of a loose woman? such a thing may not be. 16 Or do you not see that he who is joined to a loose woman is one body with her? for God has said, The two of them will become one flesh. 17 But he who is united to the Lord is one spirit. 18 Keep away from the desires of the flesh. Every sin which a man does is outside of the body; but he who goes after the desires of the flesh does evil to his body.
Matthew Henry's Commentary on 1 Corinthians 6:12-18
Commentary on 1 Corinthians 6:12-20
(Read 1 Corinthians 6:12-20)
Some among the Corinthians seem to have been ready to say, All things are lawful for me. This dangerous conceit St. Paul opposes. There is a liberty wherewith Christ has made us free, in which we must stand fast. But surely a Christian would never put himself into the power of any bodily appetite. The body is for the Lord; is to be an instrument of righteousness to holiness, therefore is never to be made an instrument of sin. It is an honour to the body, that Jesus Christ was raised from the dead; and it will be an honour to our bodies, that they will be raised. The hope of a resurrection to glory, should keep Christians from dishonouring their bodies by fleshly lusts. And if the soul be united to Christ by faith, the whole man is become a member of his spiritual body. Other vices may be conquered in fight; that here cautioned against, only by flight. And vast multitudes are cut off by this vice in its various forms and consequences. Its effects fall not only directly upon the body, but often upon the mind. Our bodies have been redeemed from deserved condemnation and hopeless slavery by the atoning sacrifice of Christ. We are to be clean, as vessels fitted for our Master's use. Being united to Christ as one spirit, and bought with a price of unspeakable value, the believer should consider himself as wholly the Lord's, by the strongest ties. May we make it our business, to the latest day and hour of our lives, to glorify God with our bodies, and with our spirits which are his.
