I Corinthians 9:18

What is my reward?--The answer is in Co1 9:19; namely, that by making the Gospel without charge, where I might have rightfully claimed maintenance, I might "win the more." of Christ--The oldest manuscripts and versions omit these words. abuse--rather "that I use not to the full my power." This is his matter for "glorying"; the "reward" ultimately aimed at is the gaining of the more (Co1 9:19). The former, as involving the latter, is verbally made the answer to the question, "What is my reward?" But really the "reward" is that which is the ultimate aim of his preaching without charge, namely, that he may gain the more; it was for this end, not to have matter of glorying, that he did so.

In this chapter the apostle seems to answer some cavils against himself. I. He asserts his apostolical mission and authority, and gives in his success among them as a testimony to it (Co1 9:1, Co1 9:2). II. He claims a right to subsist by his ministry, and defends it by several arguments from natural reason and the Mosaical law, and asserts it also to be a constitution of Christ (Co1 9:3-14). III. He shows that he had willingly waived this privilege and power for their benefit (Co1 9:15-18). IV. He specifies several other things, in which he had denied himself for the sake of other men's spiritual interest and salvation (Co1 9:19-23). And, V. Concludes his argument by showing what animated him to this course, even the prospect of an incorruptible crown (Co1 9:24 to the end.)

9:18 Paul’s satisfaction came from preaching the Good News without charging anyone. This is another example of the way Christians must be willing to give up their rights out of consideration for others (cp. 8:13).
