But we are bound to always give thanks to God for you, brothers loved by the Lord, because God chose you from the beginning for salvation through sanctification of the Spirit and belief in the truth;
In sanctification of the spirit, says he, and belief of the truth. This may be explained in two ways, with sanctification, or by sanctification. It is not of much importance which of the two you select, as it is certain (688) that Paul meant simply to introduce, in connection with election, those nearer tokens which manifest to us what is in its own nature incomprehensible, and are conjoined with it by an indissoluble tie. Hence, in order that we may know that we are elected by God, there is no occasion to inquire as to what he decreed before the creation of the world, but we find in ourselves a satisfactory proof if he has sanctified us by his Spirit, — if he has enlightened us in the faith of his gospel. For the gospel is an evidence to us of our adoption, and the Spirit seals it, and those that are led by the Spirit are the sons of God, (Romans 8:14,) and he who by faith possesses Christ has everlasting life. (1 John 5:12.) These things must be carefully observed, lest, overlooking the revelation of God’s will, with which he bids us rest satisfied, we should plunge into a profound labyrinth from a desire to take it from his secret counsel, from the investigation of which he draws us aside. Hence it becomes us to rest satisfied with the faith of the gospel, and that grace of the Spirit by which we have been regenerated. And by this means is refuted the wickedness (689) of those who make the election of God a pretext for every kind of iniquity, while Paul connects it with faith and regeneration in such a manner, that he would not have it judged of by us on any other grounds.
