1 Corinthians 9:24-27 says, “Do you not know that in a race all the runners run, but only one receives the prize? So run that you may obtain it.  Every athlete exercises self-control in all things. They do it to receive a perishable wreath, but we an imperishable.  So I do not run aimlessly; I do not box as one beating the air.  But I discipline my body and keep it under control, lest after preaching to others I myself should be disqualified.”
The Christian life is one of self control. We must control our actions and bring our bodies in subjection. If we cannot control our bodies, then we cannot accomplish anything.
