Discipline–Spiritual Sweat
In a word, he is calling for some spiritual sweat! Just as athletes discarded everything and competed gymnos [naked] – – free from everything that could possibly burden them – – so we must get rid of every encumbrance, every association, habit, and tendency which impedes godliness. If we are to excel, we must strip ourselves to a lean, spiritual nakedness. The writer of Hebrews explains it like this: “Therefore, since we are surrounded by such a great cloud of witnesses, let us throw off everything that hinders and the sin that so easily entangles, and let us run with perseverance the race marked out for us (Hebrews 12:2). Men, we will never get anywhere spiritually without a conscious divestment of the things that are holding us back. What things are weighing you down? The call to discipline demands that you throw it off. Are you man enough?
