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.
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,
as not without aim; I box in such a way,
as not beating the air; but I discipline my body
and make it my slave, so that,
after I have preached to others, I myself will not be disqualified.
1 Corinthians 9:24-27
