1 Corinthians 9:19-23

Although I am free from all and not anyone’s slave, I have made myself a slave to everyone, in order to win more people. To the Jews I became like a Jew, to win Jews; to those under the law, like one under the law — though I myself am not under the law  — to win those under the law. To those who are without the law, like one without the law — though I am not without God’s law but under the law of Christ — to win those without the law. To the weak I became weak, in order to win the weak. I have become all things to all people, so that I may by every possible means save some. Now I do all this because of the gospel, so that I may share in the blessings.
