If I proclaim the gospel, this gives me no ground for boasting, for an obligation is laid on me, and woe to me if I do not proclaim the gospel! For if I do this of my own will, I have a reward; but if not of my own will, I am entrusted with a commission. What then is my reward? Just this: that in my proclamation I may make the gospel free of charge, so as not to make full use of my rights in the gospel.
For though I am free with respect to all, I have made myself a slave to all, so that I might win more of them. To the weak I became weak, so that I might win the weak. I have become all things to all people, that I might by all means save some. I do it all for the sake of the gospel, so that I may share in its blessings.
Do you not know that in a race the runners all compete, but only one receives the prize? Run in such a way that you may win it. Athletes exercise self-control in all things; they do it to receive a perishable wreath, but we an imperishable one. So I do not run aimlessly, nor do I box as though beating the air; but I punish my body and enslave it, so that after proclaiming to others I myself should not be disqualified.
