1 Corinthians 9:22-26

24 Don’t you realize that in a race everyone runs, but only one person gets the prize? So run to win! 25 All athletes are disciplined in their training. They do it to win a prize that will fade away, but we do it for an eternal prize. 26 So I run with purpose in every step. I am not just shadowboxing. 27 I discipline my body like an athlete, training it to do what it should. Otherwise, I fear that after preaching to others I myself might be disqualified.
