1 Corinthians 9:24-27
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.
1 Timothy 4:7-10
7 Do not waste time arguing over godless ideas and old wives’ tales. Instead, train yourself to be godly. 8 “Physical training is good, but training for godliness is much better, promising benefits in this life and in the life to come.” 9 This is a trustworthy saying, and everyone should accept it. 10 This is why we work hard and continue to struggle,[a] for our hope is in the living God, who is the Savior of all people and particularly of all believers.
