7 and the profane and old women's fables reject thou, and exercise thyself unto piety, 8 for the bodily exercise is unto little profit, and the piety is to all things profitable, a promise having of the life that now is, and of that which is coming;
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.
