1 Corinthians 9:24-25

Do you not know that in a race all the runners compete, but [only] one receives the prize? So run [your race] that you may lay hold [of the prize] and make it yours. Now every athlete who goes into training conducts himself temperately and restricts himself in all things. They do it to win a wreath that will soon wither, but we [do it to receive a crown of eternal blessedness] that cannot wither.
