"Do you not know that those who run in a race all run, but only one receives the prize? Run in such a way that you may win. And everyone who competes in the games exercises self-control in all things. They then do it to receive a perishable wreath, but we an imperishable. Therefore, I run in such a way, not as without aim; I box in such a way, as not beating the air; but I buffet my body and make it my slave, lest possibly, after I have preached to others, I myself should be disqualified." (I Corinthians 9:24-27).
