24 Know you not that they that run in the race, all run indeed, but one receiveth the prize ? So run that you may obtain.25 And every one that striveth for the mastery, refraineth himself from all things: and they indeed that they may receive a corruptible crown; but we an incorruptible one.26 I therefore so run, not as at an uncertainty: I so fight, not as one beating the air:27 But I chastise my body, and bring it into subjection: lest perhaps, when I have preached to others, I myself should become a castaway.
