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.

1Co 6:12-20. Refutation of the Antinomian Defense of Fornication as if It Was Lawful Because Meats Are So.

12. All things are lawful unto me—These, which were Paul's own words on a former occasion (to the Corinthians, compare 1Co 10:23, and Ga 5:23), were made a pretext for excusing the eating of meats offered to idols, and so of what was generally connected with idolatry (Ac 15:29), "fornication" (perhaps in the letter of the Corinthians to Paul, 1Co 7:1). Paul's remark had referred only to things indifferent: but they wished to treat fornication as such, on the ground that the existence of bodily appetites proved the lawfulness of their gratification.

me—Paul giving himself as a sample of Christians in general.

but I—whatever others do, I will not, &c.

lawful … brought under the power—The Greek words are from the same root, whence there is a play on the words: All things are in my power, but I will not be brought under the power of any of them (the "all things"). He who commits "fornication," steps aside from his own legitimate power or liberty, and is "brought under the power" of an harlot (1Co 6:15; compare 1Co 7:4). The "power" ought to be in the hands of the believer, not in the things which he uses [Bengel]; else his liberty is forfeited; he ceases to be his own master (Joh 8:34-36; Ga 5:13; 1Pe 2:16; 2Pe 2:19). Unlawful things ruin thousands; "lawful" things (unlawfully used), ten thousands.
