1-е Коринфянам 9:16

though I preach . . . I have nothing to glory of--that is, If I preach the Gospel, and do so not gratuitously, I have no matter for "glorying." For the "necessity" that is laid on me to preach (compare Jer 20:9, and the case of Jonah) does away with ground for "glorying." The sole ground for the latter that I have, is my preaching without charge (Co1 9:18): since there is no necessity laid on me as to the latter, it is my voluntary act for the Gospel's sake.

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.)

9:16 compelled by God to do it: Acts 22:14-15; 26:16-18.
