That which Thou saidst in the beginning of the creation, Let there be light, and there was light; I do, not unsuitably, understand of the spiritual creature: because there was already a sort of life, which Thou mightest illuminate. But as it had no claim on Thee for a life, which could be enlightened, so neither now that it was, had it any, to be enlightened. For neither could its formless estate be pleasing unto Thee, unless it became light, and that not by existing simply, but by beholding the illuminating light, and cleaving to it; so that, that it lived, and lived happily, it owes to nothing but Thy grace, being turned by a better change unto That which cannot be changed into worse or better; which Thou alone art, because Thou alone simply art; unto Thee it being not one thing to live, another to live blessedly, seeing Thyself art Thine own Blessedness.
