1 Corinthians 9:19-23
19 And this has a real advantage: I am not bound to obey anyone just because he pays my salary; yet I have freely and happily become a servant of any and all so that I can win them to Christ. 20 When I am with the Jews I seem as one of them so that they will listen to the Gospel and I can win them to Christ. When I am with Gentiles who follow Jewish customs and ceremonies I don’t argue, even though I don’t agree, because I want to help them. 21 When with the heathen I agree with them as much as I can, except of course that I must always do what is right as a Christian. And so, by agreeing, I can win their confidence[a] and help them too.
22 When I am with those whose consciences bother them easily, I don’t act as though I know it all and don’t say they are foolish; the result is that they are willing to let me help them. Yes, whatever a person is like, I try to find common ground with him so that he will let me tell him about Christ and let Christ save him. 23 I do this to get the Gospel to them and also for the blessing I myself receive when I see them come to Christ.Read full chapter
