1 Corinthians 9:19-27 - Paul's Work As An Apostle
19 For though I am free from all, yet I have made myself servant to all, so that I might gain the more. 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. 23 And this I do for the sake of the gospel, so that I might be partaker of it with you.
24 Do you not know that those running in a race all run, but one receives the prize? So run, that you may obtain. 25 And everyone who strives for the mastery is temperate in all things. Then those truly that they may receive a corruptible crown, but we an incorruptible. 26 So then I run, not as if I were uncertain. And so I fight, not as one who beats the air. 27 But I buffet my body, and lead it captive, lest proclaiming to others I myself might be rejected.
