14 And the grace of our Lord He again magnifies the grace of God towards himself, not only for the purpose of removing the dislike of it and testifying his gratitude, but also to employ it as a shield against the slanders of wicked men, whose whole design was to bring down his apostleship to a lower level. When he says that it abounded, and that, too, beyond measure, the statement implies that the remembrance of past transactions was effaced, and so completely swallowed up, that it was no disadvantage to him that God had formerly been gracious to good men.
With faith and love Both may be viewed as referring to God, in this sense, that God showed himself to be true, and gave a manifestation of his love in Christ, when he bestowed his grace upon him. But I prefer a more simple interpretation, that “faith and love” are indications and proofs of that grace which he had mentioned, that it might not be supposed that he boasted needlessly or without good grounds. And, indeed, “faith” is contrasted with unbelief, and “love in Christ” is contrasted with the cruelty which he had exercised towards believers; as if he had said, that God had so completely changed him, that he had become a totally different and new man. Thus from the signs and effects he celebrates in lofty terms the excellence of that grace which must obliterate the remembrance of his former life.
