4:8 {12} For bodily exercise profiteth little: but godliness is profitable unto all things, having promise of the life that now is, and of that which is to come.
(12) Godliness consists in spiritual exercise, and not in outward strictness of life, which though it is something to be esteemed, if it is used correctly, yet it is in no way comparable with godliness. For it profits not in and of itself, but through the benefit of another; but godliness has the promise both of the present life, and of that which is to come.
4:8 For bodily exercise profiteth little. The Greeks gave great attention to bodily training. At Ephesus, where Timothy was, may still be seen the remains of the stadium where the athletes displayed their skill. Let Christians display the same assiduity in training for godliness.
Godliness is profitable in all things. Godly training makes men happier, more prosperous, more healthy here, and in addition it prepares them for the life to come. The way to reach heaven is not either to starve or to exercise the body.
4:8 Bodily exercise profiteth a little - Increases the health and strength of the body.
4:6-10 Outward acts of self-denial profit little. What will it avail us to mortify the body, if we do not mortify sin? No diligence in mere outward things could be of much use. The gain of godliness lies much in the promise; and the promises to godly people relate partly to the life that now is, but especially to the life which is to come: though we lose for Christ, we shall not lose by him. If Christ be thus the Saviour of all men, then much more will he be the Rewarder of those who seek and serve him; he will provide well for those whom he has made new creatures.
