16For when I preach the gospel, I cannot boast, since I am compelled to preach. Woe to me if I do not preach the gospel!17If I preach voluntarily, I have a reward; if not voluntarily, I am simply discharging the trust committed to me.18What then is my reward? Just this: that in preaching the gospel I may offer it free of charge, and so not make full use of my rights as a preacher of the gospel.19Though I am free and belong to no one, I have made myself a slave to everyone, to win as many as possible.
22To the weak I became weak, to win the weak. I have become all things to all people so that by all possible means I might save some.23I do all this for the sake of the gospel, that I may share in its blessings.24Do you not know that in a race all the runners run, but only one gets the prize? Run in such a way as to get the prize.25Everyone who competes in the games goes into strict training. They do it to get a crown that will not last, but we do it to get a crown that will last forever.26Therefore I do not run like someone running aimlessly; I do not fight like a boxer beating the air.27No, I strike a blow to my body and make it my slave so that after I have preached to others, I myself will not be disqualified for the prize.
