19 For though I am free from all men, I have made myself a slave to all, that I might win the more. 20 To the Jews I became as a Jew, in order to win Jews; to those under the law I became as one under the law--though not being myself under the law--that I might win those under the law. 21 To those outside the law I became as one outside the law--not being without law toward God but under the law of Christ--that I might win those outside the law. 22 To the weak I became weak, that I might win the weak. I have become all things to all men, that I might by all means save some. 23 I do it all for the sake of the gospel, that I may share in its blessings.

24 Do you not know that in a race all the runners compete, but only one receives the prize? So run that you may obtain it. 25 Every athlete exercises self-control in all things. They do it to receive a perishable wreath, but we an imperishable. 26 Well, I do not run aimlessly, I do not box as one beating the air; 27 but I pommel my body and subdue it, lest after preaching to others I myself should be disqualified.

Commentary on 1 Corinthians 9:15-23

(Read 1 Corinthians 9:15-23)

It is the glory of a minister to deny himself, that he may serve Christ and save souls. But when a minister gives up his right for the sake of the gospel, he does more than his charge and office demands. By preaching the gospel, freely, the apostle showed that he acted from principles of zeal and love, and thus enjoyed much comfort and hope in his soul. And though he looked on the ceremonial law as a yoke taken off by Christ, yet he submitted to it, that he might work upon the Jews, do away their prejudices, prevail with them to hear the gospel, and win them over to Christ. Though he would transgress no laws of Christ, to please any man, yet he would accommodate himself to all men, where he might do it lawfully, to gain some. Doing good was the study and business of his life; and, that he might reach this end, he did not stand on privileges. We must carefully watch against extremes, and against relying on any thing but trust in Christ alone. We must not allow errors or faults, so as to hurt others, or disgrace the gospel.

Commentary on 1 Corinthians 9:24-27

(Read 1 Corinthians 9:24-27)

The apostle compares himself to the racers and combatants in the Isthmian games, well known by the Corinthians. But in the Christian race all may run so as to obtain. There is the greatest encouragement, therefore, to persevere with all our strength, in this course. Those who ran in these games were kept to a spare diet. They used themselves to hardships. They practised the exercises. And those who pursue the interests of their souls, must combat hard with fleshly lusts. The body must not be suffered to rule. The apostle presses this advice on the Corinthians. He sets before himself and them the danger of yielding to fleshly desires, pampering the body, and its lusts and appetites. Holy fear of himself was needed to keep an apostle faithful: how much more is it needful for our preservation! Let us learn from hence humility and caution, and to watch against dangers which surround us while in the body.
