1 Corinthians 9:19-22

Moffatt(i) 19 Why, free as I am from all, I have made myself the slave of all, to win over as many as I could. 20 To Jews I have become like a Jew, to win over Jews; to those under the Law I have become as one of themselves — though I am not under the Law myself — to win over those under the Law; 21 to those outside the Law I have become like one of themselves — though I am under Christ's law, not outside God's Law — to win over those outside the Law; 22 to the weak I have become as weak myself, to win over the weak. To all men I have become all things, to save some by all and every means.
