1 Corinthians 9:25-27

VIN(i) 25 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. 26 Therefore I do not run aimlessly; I do not fight like I am beating the air. 27 No, I discipline my body and make it my slave, so that after I have preached to others, I myself will not be disqualified.
