1 Coríntios 9

24 Do you not know that those who run in a race all run, but one receives the prize? Run like that, that you may win.

25 Every man who strives in the games exercises self-control in all things. Now they do it to receive a corruptible crown, but we an incorruptible.

26 I therefore run like that, as not uncertainly. I fight like that, as not beating the air,

27 but I beat my body and bring it into submission, lest by any means, after I have preached to others, I myself should be rejected.
