God makes the works of his wisdom more beautiful through contrast

if Adam had never fallen, the whole human race would have been a series of magnificently different and splendid images of God, each one of all the millions of men showing forth His glories and perfections in an astonishing new way, and each one shining with his own particular sanctity, a sanctity destined for him from all eternity as the most complete and unimaginable supernatural perfection of his human personality. If, since the fall, this plan will never be realized in millions of souls, and millions will frustrate that glorious destiny of theirs, and hide their personality in an eternal corruption of disfigurement, nevertheless, in re-forming His image in souls distorted and half destroyed by evil and disorder, God makes the works of His wisdom and love all the more strikingly beautiful by reason of the contrast with the surroundings in which He does not disdain to operate.
