16. For if I [merely] preach the Gospel, that gives me no reason to boast, for I feel compelled of necessity to do it. Woe is me if I do not preach the glad tidings (the Gospel)!
17. For if I do this work of my own free will, then I have my pay (my reward); but if it is not of my own will, but is done reluctantly and under compulsion, I am [still] entrusted with a [sacred] trusteeship and commission.
18. What then is the [actual] reward that I get? Just this: that in my preaching the good news (the Gospel), I may offer it [absolutely] free of expense [to anybody], not taking advantage of my rights and privileges [as a preacher] of the Gospel.
19. For although I am free in every way from anyone's control, I have made myself a bond servant to everyone, so that I might gain the more [for Christ].
