1 Corinthians 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 Jeremiah 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 (I Corinthians 9:18): since there is no necessity laid on me as to the latter, it is my voluntary act for the Gospel's sake.
