How the Knowledge of God Differs from that of Man.
The Confessions · Saint Augustine of Hippo
41. O Lord my God, what is that secret place of Thy mystery, and how far thence have the consequences of my transgressions cast me? Heal my eyes, that I may enjoy Thy light. Surely, if there be a mind, so greatly abounding in knowledge and foreknowledge, to which all things past and future are so known as one psalm is well known to me, that mind is exceedingly wonderful, and very astonishing; because whatever is so past, and whatever is to come of after ages, is no more concealed from Him than was it hidden from me when singing that psalm, what and how much of it had been sung from the beginning, what and how much remained unto the end. But far be it that Thou, the Creator of the universe, the Creator of souls and bodies,—far be it that Thou shouldest know all things future and past. Far, far more wonderfully, and far more mysteriously, Thou knowest them. For it is not as the feelings of one singing known things, or hearing a known song, are—through expectation of future words, and in remembrance of those that are past—varied, and his senses divided, that anything happeneth unto Thee, unchangeably eternal, that is, the truly eternal Creator of minds. As, then, Thou in the Beginning knewest the heaven and the earth without any change of Thy knowledge, so in the Beginning didst Thou make heaven and earth without any distraction of Thy action. Let him who understandeth confess unto Thee; and let him who understandeth not, confess unto Thee. Oh, how exalted art Thou, and yet the humble in heart are Thy dwelling-place; for Thou raisest up those that are bowed down, and they whose exaltation Thou art fall not.
