Let us suppose a man in the world, held fast as yet in the love of this world and of his flesh; and, inasmuch as he bears the image of the earthly man, occupied with earthly things, without a thought of things heavenly, can any one fail to see that this man is surrounded with horrible darkness, unless he also is sitting in the same fatal gloom? For no sign of his salvation has yet shone upon him; no inner inspiration bears its witness in his heart as to whether an eternal predestination destines him to good.
But, then, suppose the heavenly compassion vouchsafes sometime to have regard to him, and to shed upon him a spirit of compunction to make him bemoan himself and learn wisdom, change his life, subdue his flesh, love his neighbour, cry to God, and resolve hereafter to live to God and not to the world; and suppose that thenceforward, by the gracious visitation of heavenly light and the sudden change accomplished by the Right Hand of the Most High he sees clearly that he is no longer a child of wrath, but of grace, for he is now experiencing the fatherly love and divine goodness towards him—a love which hitherto had been concealed from him so completely as not only to leave him in ignorance whether he deserved love or hate, but also as to make his own life indicate hatred rather than love, for darkness was still on the face of the deep—would it not seem to you that such an one is lifted directly out of the profoundest and darkest deep of horrible ignorance into the pleasant and serene deep of eternal brightness?
Bernard of Clairvaux, Letter XL to Thomas, Prior of Beverley
