For bodily exercise profits for a little while: but godliness is profitable unto all things, having promise of the life that now is, and of that which is to come.
All Commentaries on 1 Timothy 4:8 Go To 1 Timothy 4
John Chrysostom
AD 407
For bodily exercise profits little. This has by some been referred to fasting; but away with such a notion! For that is not a bodily but a spiritual exercise. If it were bodily it would nourish the body, whereas it wastes and makes it lean, so that it is not bodily. Hence he is not speaking of the discipline of the body. What we need, therefore, is the exercise of the soul. For the exercise of the body has no profit, but may benefit the body a little, but the exercise of godliness yields fruit and advantage both here and hereafter.
This is a faithful saying, that is, it is true that godliness is profitable both here and hereafter. Observe how everywhere he brings in this, he needs no demonstration, but simply declares it, for he was addressing Timothy.
So then even here, we have good hopes? For he who is conscious to himself of no evil, and who has been fruitful in good, rejoices even here: as the wicked man on the other hand is punished here as well as hereafter. He lives in perpetual fear, he can look no one in the face with confidence, he is pale, trembling, and full of anxiety. Is it not so with the fraudulent, and with thieves, who have no satisfaction even in what they possess? Is not the life of murderers and adulterers most wretched, who look upon the sun itself with suspicion? Is this to be called life? No; rather a horrid death!
