1 Corinthians 9:21-22

Mace(i) 21 to those who are without the law, as without that law, (not as being under no law to God, but as under the law to Christ) that I might gain those who are without the law. 22 to the weak I became as weak, that I might gain the weak: I became all things to all men, that I might save all sorts of men.
