I Corinthians 9:24-27
Do you not know that in a race all the runners
run, but only one gets the prize? Run in such
a way as to get the prize. Everyone who
competes in the games goes into strict training.
They do it to get a crown that will not last;
but we do it to get a crown that will last
forever. Therefore, I do not run like a man
running aimlessly; I do not fight like a man
beating the air. No, I beat my body and make
it my slave so that after I have preached to
others, I myself will not be disqualified for
the prize
