7 but refuse profane and old wives' fables. And exercise thyself unto godliness: 8 for bodily exercise is profitable for a little; but godliness is profitable for all things, having promise of the life which now is, and of that which is to come. 9 Faithful is the saying, and worthy of all acceptation. 10 For to this end we labor and strive, because we have our hope set on the living God, who is the Saviour of all men, specially of them that believe.
Matthew Henry's Commentary on 1 Timothy 4:7-10
Commentary on 1 Timothy 4:6-10
(Read 1 Timothy 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.
