That Nothing Arose Save by the Gift of God
11 Happy creature, which, though in itself it was other than You, has known no other state than that as soon as it was made, it was, without any interval of time, by Your Gift, which is borne over everything mutable, raised up by that calling whereby Thou said, “Let there be light, and there was light.” Whereas in us there is a difference of times, in that we were darkness, and are made light; but of that it is only said what it would have been had it not been enlightened. And this is so spoken as if it had been fleeting and darksome before; that so the cause whereby it was made to be otherwise might appear—that is to say, being turned to the unfailing Light it might become light. Let him who is able understand this; and let him who is not, ask of You. Why should he trouble me, as if I could enlighten any “man that comes into the world?”
