1 Corinthians 9:19-27 - Paul's Work As An Apostle
19 For though I be free from all men, yet have I made myself servant unto all men, that I might win the more. 20 And unto the Jews, I became as a Jew, to win the Jews. To them that were under the law, was I made as though I had been under the law, to win them that were under the law. 21 To them that were without law, became I as though I had been without law - when I was not without law as pertaining to God, but under a law as concerning Christ - to win them that were without law. 22 To the weak became I as weak, to win the weak. In all thing I fashioned myself to all men, to save, at the leastway, some. 23 And this I do for the Gospel's sake, that I might have my part thereof.
24 Perceive ye not how that they which run in a course, run all, yet but one receiveth the reward? So run that ye may obtain. 25 Every man that proveth masteries abstaineth from all things. And they do it to obtain a corruptible crown: but we to obtain an uncorruptible crown. 26 I therefore so run, not as at an uncertain thing. So fight I, not as one that beateth the air: 27 but I tame my body and bring it into subjection, lest after that I have preached to others, I myself should be a castaway.
