1 Corinthians 9:16-18

Twentieth_Century(i) 16 If I tell the Good News, I have nothing to boast of, for I can but do so. Woe is me if I do not tell it! 17 If I do this work willingly, I have a reward; but, if unwillingly, I have been charged to perform a duty. 18 What is my reward, then? To present the Good News free of all cost, and so make but a sparing use of the rights which it gives me.
