1 Corinthians 9:24-26

Williams(i) 24 Do you not know that in a race the runners all run, but only one can get the prize? You must run in such a way that you can get the prize. 25 Any man who enters an athletic contest practices rigid self-control in training, only to win a wreath that withers, but we are in to win a wreath that never withers. 26 So that is the way I run, with no uncertainty as to winning. That is the way I box, not like one that punches the air.
