1 Corinthians 9:20-22

MKJV(i) 20 And to the Jews I became as a Jew, so that I might gain the Jews. To those who are under the Law, I became as under the Law, so that I might gain those who are under the Law. 21 To those who are outside Law, I became as outside Law (not being outside law to God, but under the Law to Christ), so that I might gain those who are outside Law. 22 To the weak I became as the weak, so that I might gain the weak. I am made all things to all men, so that I might by all means save some.
