 1 Corinthians 9, 17. For if I do this willingly, I have a reward. But if it's against my will, I have been entrusted with a stewardship. What is my reward then? That when I preach the gospel, that's the good news of the Lord Jesus Christ, that I may present the gospel of Christ without charge. You hear that? Without charge. That I may not abuse my authority in the gospel.
