15But I have not used any of these rights. And I am not writing this in the hope that you will do such things for me, for I would rather die than allow anyone to deprive me of this boast. 16For when I preach the gospel, I cannot boast, since I am compelled to preach. Woe to me if I do not preach the gospel! 17If I preach voluntarily, I have a reward; if not voluntarily, I am simply discharging the trust committed to me.
