1 Corinthians 9:17-22

9:17 For if I do this voluntarily, I have a reward. But if I do it unwillingly, I am entrusted with a responsibility. 9:18 What then is my reward? That when I preach the gospel I may offer the gospel free of charge, and so not make full use of my rights in the gospel.

9:19 For since I am free from all I can make myself a slave to all, in order to gain even more people. 9:20 To the Jews I became like a Jew to gain the Jews. To those under the law I became like one under the law (though I myself am not under the law) to gain those under the law. 9:21 To those free from the law I became like one free from the law (though I am not free from God’s law but under the law of Christ) to gain those free from the law. 9:22 To the weak I became weak in order to gain the weak. I have become all things to all people, so that by all means I may save some.
