1 Corinthians 9:18-20

Amplified Bible

¹⁸ What then is my reward? [Just this:] that, when I preach the gospel, I may offer the gospel without charge [to everyone], so as not to take advantage of my rights [as a preacher and apostle] in [preaching] the gospel.

¹⁹ For though I am free from all men, I have made myself a slave to everyone, so that I may win more [for Christ]. ²⁰ To the Jews I became as a Jew, so that I might win Jews [for Christ]; to men under the Law, [I became] as one ^[a]under the Law, though not being under the Law myself, so that I might win those who are under the Law.
