[24]Know ye not that they which run in a race run all, but one receiveth the prize? So run, that ye may obtain.[25]And every man that striveth for the mastery is temperate in all things. Now they do it to obtain a corruptible crown; but we an incorruptible.[26]I therefore so run, not as uncertainly; so fight I, not as one that beateth the air:[27]But I keep under my body, and bring it into subjection: lest that by any means, when I have preached to others, I myself should be a castaway.
