In the heavenly race a lot of defeat is from slothfulness, we want something for nothing, but just as the athlete is called to manage his body so is the Christian. It is no small thing to control your appetite, and no little challenge to regulate sleep. Yet Paul says to conquer your body and keep it under control; to “exercise self-control in all things”, remembering that we will receive an imperishable wreath.
