1 Corinthians 9:24-27 - The Need For Self-Discipline
24 Do you not know that those running in the stadium, indeed all run, and one receives the prize? So run, that you may receive it. 25 But every one contesting is abstinent in all things, they indeed also that they may receive a corruptible crown, but we an incorruptible. 26 I therefore so run, not as uncertainly, do I thus fight not as beating the air: 27 but I keep my body under, and enslave it, lest having preached the gospel to others, I myself may become disapproved.
