1 Corinthians 9:19-27 - Paul's Work As An Apostle
19 For, though I am free from all persons, yet I have made myself a servant to all, that I might gain more. 20 To the Jews I became as a Jew, that I might gain the Jews. To those under the Law, as under the Law, that I might gain those under the Law. 21 To those without Law I became like those without Law that I might gain them. I am not without law to God, but under the law to (toward) (of) Christ. 22 To the weak I became as the weak, that I might gain the weak. I am made all things to all men, that I might by all means save some. 23 And this I do for the sake of the good news that I might be a partaker of it with others.
24 Do you not know that they who run in a race all run, but one receives the prize? So run that you may obtain the prize. 25 Every man taking part in the contest is temperate in all things. They do it to obtain a corruptible crown but we do it to receive an incorruptible crown. 26 I do not run without definite aim (purpose) and I do not fight like a man beating the air. 27 But I discipline my body, and bring it into subjection, so that after I have preached to others I will not be disqualified.
