Everyone who competes in the games, trains with strict discipline. They do it for a crown that is perishable, but we do it for a crown that is imperishable. 1 Corinthians 9:25

Therefore, since we are surrounded by such a huge crowd of witnesses to the life of faith, let us strip off every weight that slows us down, especially the sin that so easily trips us up. And let us run with endurance the race God has set before us. Hebrews 12:1
