1 Corinthians 9:16-19

16I tell God's good news to people. But I have no reason to be proud because of that. It is something that I have to do. If I did not tell the good news, it would bring me great trouble.

17If I were doing this work because I chose to do it, I would receive my pay. But I myself did not choose to do it. God has given me this work, so I have to do it.

18So what kind of pay do I receive? It is this: I do not take any money from people when I tell them God's good news. I do not use all the authority that I could use when I tell God's good news to people.

19Yes, I am a free man. I am not anybody's slave. But I choose to serve everybody like a slave. I do that so that I can help many more people to believe in Christ.
