How do athletes train for a race? They modify their entire lifestyle for the sake of this one great objective which they set before them. The lengths to which those athletically gifted will go are impressive.
Self-control is a massive issue in the Christian life. Watching our time; keeping our devotions; keeping up the concern for holiness of life; self-examination; repentance; commitment of the Lord; restraint over things that would divert our attention and take us away from these duties. We too, like the athlete, must watch how we spend our time; we must be careful not to pamper ourselves. We examine the departments of our lives and note when we begin to drift in any respect.
