1 Corinthians 9:24-27 - The Need For Self-Discipline
24 Do you not know that in a foot-race, though all run, only one receives the prize? So run that you may win. 25 Every man who contends in the games continually trains himself by all manner of self-restraint. Now they do it to get a fading garland, but we, one that is unfading. 26 For my part, then, I run with no wavering to the goal. I box not as one beating the air, 27 but I bruise my body and keep it in subjection, lest having called others to the contest, I should myself be disqualified.
