"THE grace of God could not have been more graciously commended to us than thus, that the only Son of God, remaining unchangeable in Himself, should assume humanity, and should give us the hope of His love, by means of the mediation of a human nature, through which we, from the condition of men, might come to Him who was so far off,—the immortal from the mortal; the unchangeable from the changeable; the just from the unjust; the blessed from the wretched. And, as He had given us a natural instinct to desire blessedness and immortality, He Himself continuing to be blessed, but assuming mortality, by enduring what we fear, taught us to despise it, that what we long for He might bestow upon us."
~St. Augustine: The City of God, Book X, Chap. 29.
