1 Corinthians 9:23-25

I do all this for the sake of the gospel, that I may share in its blessings. 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.
