For you [God] are infinite and never change. In you 'today' never comes to an end: and yet our 'today' does come to an end in you, because time, as well as everything else, exists in you. If it did not, it would have no means of passing. And since your years never come to an end, for you they are simply 'today'...But you yourself are eternally the same. In your 'today' you will make all that is to exist tomorrow and thereafter, and in your 'today' you have made all that existed yesterday and for ever before.

Author: Augustine of Hippo
