18 Flee from sexual immorality. All other sins a person commits are outside the body, but whoever sins sexually, sins against their own body.
English Standard Version
18 Flee from sexual immorality. Every other sinOr Every sin a person commits is outside the body, but the sexually immoral person sins against his own body.
18 There is a sense in which sexual sins are different from all others. In sexual sin we violate the sacredness of our own bodies, these bodies that were made for God-given and God-modeled love, for "becoming one" with another.
New King James Version
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.
New Living Translation
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.
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.
