For it is one thing for existence to be endlessly prolonged, which was what Plato ascribed to the world, another for the whole of an endless life to be embraced in the present, which is manifestly a property peculiar to the Divine mind.

Nor need God appear earlier in mere duration of time to created things, but only prior in the unique simplicity of His nature.
For the infinite progression of things in time copies this immediate existence in the present of the changeless life, and when it cannot succeed in equalling it, declines from movelessness into motion, and falls away from the simplicity of a perpetual present to the infinite duration of the future and the past; and since it cannot possess the whole fulness of its life together, for the very reason that in a manner it never ceases to be, it seems, up to a certain point, to rival that which it cannot complete and express by attaching itself indifferently to any present moment of time, however swift and brief; and since this bears some resemblance to that ever-abiding present, it bestows on everything to which it is assigned the semblance of existence.

But since it cannot abide, it hurries along the infinite path of time, and the result has been that it continues by ceaseless movement the life the completeness of which it could not embrace while it stood still.

So, if we are minded to give things their right names, we shall follow Plato in saying that God indeed is eternal, but the world everlasting.
'Since, then, every mode of judgment comprehends its objects conformably to its own nature, and since God abides for ever in an eternal present, His knowledge, also transcending all movement of time, dwells in the simplicity of its own changeless present, and, embracing the whole infinite sweep of the past and of the future, contemplates all that falls within its simple cognition as if it were now taking place.

And therefore, if thou wilt carefully consider that immediate presentment whereby it discriminates all things, thou wilt more rightly deem it not foreknowledge as of something future, but knowledge of a moment that never passes.
