(17) For if I do this thing willingly, I have a reward.--The previous words, "Yea, woe is unto me if I preach not the gospel," are a parenthesis; and now the writer proves the truth of his assertion--that the necessity of preaching the gospel deprives the mere act itself of any grounds of boasting--by showing that if there were no necessity there would be a ground of boasting. The argument is this:--Suppose it to be otherwise, and that there is no such necessity, then, by voluntarily undertaking it, I have a reward. The undertaking it of my own free will would entitle me to a reward. But if (as is the case) not of my free will, but of necessity, then I am merely a steward--a slave doing his duty (1Corinthians 4:1; Luke 17:7-10).

A dispensation of the gospel is committed unto me.--Better, I am entrusted with a stewardship.

Verse 17. - If I do this thing willingly. The word rather means "spontaneously;" "without compulsion." He was preaching willingly, but still it was in obedience to an irresistible behest (Acts 9:6, 15). I have a reward. The reward (or rather, "wage ") of such self chosen work would be the power to fulfil it (comp. Matthew 6:1). Against my will; rather, involuntarily, "under Divine constraint." A dispensation. He was appointed a "steward" or "dispenser" of the gospel, and could only regard himself at the best as "an unprofitable slave," who had done merely what it was his bare duty to do (Luke 17:10). There is no merit in yielding to a must.

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.For if I do this thing willingly,.... That is, not freely and without receiving anything for preaching, without seeking any temporal profits and advantages; nor in pure love to Christ, and the good of souls, without any fear of punishment, or hope of reward; but the apostle supposes a case which was not, and his sense is, that supposing no necessity had been laid upon him, or any injunction or command given him to preach the Gospel, but he had entered on it without any obligation upon him, then, says he,

I have a reward; or should have one, or might expect one; so the Jews (q) say, that a reward is given to him, who does anything unbidden:

but if against my will, or unwillingly,

a dispensation of the Gospel is committed to me; which was his case; the Gospel was committed to his trust, as anything is to the trust and charge of a steward by his lord, who is obliged to take care of it, and is accountable for it, and of whom faithfulness is required; he did not undertake this economy, or dispensation of the Gospel of himself, of his own mind and will, but it was enjoined him by one that had the command over him, and could and did oblige him to take the charge of it; though he made him willing, as well as able to do it: and therefore since this was the case, that it was not at his own option whether he would preach the Gospel or not, but he was obliged to it by one, that had a superior power and influence over him; hence, though he performed it ever so well, and with never so much faithfulness and integrity, he asks in the following verse,
