13 You say, "Food was made for the stomach, and the stomach for food." (This is true, though someday God will do away with both of them.) But you can't say that our bodies were made for sexual immorality. They were made for the Lord, and the Lord cares about our bodies. 14 And God will raise us from the dead by his power, just as he raised our Lord from the dead. 15 Don't you realize that your bodies are actually parts of Christ? Should a man take his body, which is part of Christ, and join it to a prostitute? Never! 16 And don't you realize that if a man joins himself to a prostitute, he becomes one body with her? For the Scriptures say, "The two are united into one." 17 But the person who is joined to the Lord is one spirit with him. 18 Run from sexual sin! No other sin so clearly affects the body as this one does. For sexual immorality is a sin against your own body. 19 Don't you realize that your body is the temple of the Holy Spirit, who lives in you and was given to you by God? You do not belong to yourself, 20 for God bought you with a high price. So you must honor God with your body.
Matthew Henry's Commentary on 1 Corinthians 6:13-20
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.
