1 Corinthians 9:17-19

New International Version - UK

¹⁷ If I preach voluntarily, I have a reward; if not voluntarily, I am simply discharging the trust committed to me. ¹⁸ What then is my reward? Just this: that in preaching the gospel I may offer it free of charge, and so not make full use of my rights as a preacher of the gospel.

Paul’s use of his freedom

¹⁹ Though I am free and belong to no one, I have made myself a slave to everyone, to win as many as possible.
