4:9 {13} This [is] a faithful saying and worthy of all acceptation.
(13) He goes a little from his matter, and shows that those who give themselves to godliness, even though they are afflicted and reproached, are nonetheless not to be considered miserable as other men are, because they are not afflicted for that reason that other men are, and the end of them both is far different one from the other. For how can God forsake his own, who is bountiful even towards his enemies? And he wishes that this doctrine is well learned by them.
4:9 This [is] a faithful saying. A trustworthy saying. See 1Ti 4:8.
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.
