1 Corinthians 9:14-18

14In the same way, the Lord has commanded that those who preach the gospel should earn their living by the gospel.

15For my part I have used none of these rights, nor have I written these things that they may be applied in my case. For it would be better for me to die than for anyone to deprive me of my boast!

16For if I preach the gospel, I have no reason to boast, because I am compelled to preach  — and woe to me if I do not preach the gospel!

17For if I do this willingly, I have a reward, but if unwillingly, I am entrusted with a commission.

18What then is my reward? To preach the gospel and offer it free of charge and not make full use of my rights in the gospel.
