1 Cor 9:19-22
1 Co 10:31 Whether therefore ye eat, or drink, or whatsoever ye do, do all to the glory of God. 32 Give none offence, neither to the Jews, nor to the Gentiles, nor to the church of God: 33 Even as I please all men in all things, not seeking mine own profit, but the profit of many, that they may be saved.
1 Cor 9:19 For though I be free from all men, yet have I made myself servant unto all, that I might gain the more. 20 And unto the Jews I became as a Jew, that I might gain the Jews; to them that are under the law, as under the law, that I might gain them that are under the law; 21 To them that are without law, as without law, (being not without law to God, but under the law to Christ,) that I might gain them that are without law. 22 To the weak became I as weak, that I might gain the weak: I am made all things to all men, that I might by all means save some.
