I Corinthians 9:24-27
And every man that striveth for the mastery is temperate in all things.
Now they do it to obtain a corruptible crown; but we an incorruptible.
I therefore so run, not as uncertainly; so fight I, not as one that beateth the air:
But I keep under my body, and bring it into subjection: lest that by any means,
when I have preached to others, I myself should be a castaway.
and the sin which doth so easily beset us, and let us run with patience the race that is set before us,
Looking unto Jesus the author and finisher of our faith; who for the joy that was set before him endured the cross,
despising the shame, and is set down at the right hand of the throne of God.
For consider him that endured such contradiction of sinners against himself, lest ye be wearied and faint in your minds.
For by thee I have run through a troop; and by my God have I leaped over a wall.
