“The first man was so created that if he had not sinned he would always have beheld in present contemplation his Creator’s face, and by always seeing him would have loved him always, and by loving would always have clung close to him, and by clinging to him who was eternal would have possessed life without end. Evidently the one true good of man was perfect knowledge of his Creator. But he was driven from the face of the Lord, since for his sin he was struck with the blindness of ignorance, and passed from that intimate light of contemplation; and he inclined his mind to earthly desires, as he began to forget the sweetness of the divine. Thus he was made a wanderer and fugitive over the earth. A wanderer indeed, because of disordered concupiscence; and a fugitive, through guilty conscience, which feels every man’s hand against it. For every temptation will overcome the man who has lost God’s aid.
So man’s heart which had been kept secure by divine love, and one by loving One, afterward began to flow here and there through earthly desires. For the mind which knows not to love its true good is never stable and never rests. Hence restlessness, and ceaseless labor, and disquiet, until the man turns and adheres to Him. The sick heart wavers and quivers; the cause of its disease is love of the world; the remedy, the love of God.”
