Time, a creature of God - what is it?
An excerpt from The Confessions by Saint Augustine: "There was therefore never any time when you had not made anything, because you made time itself. And no phases of time are coeternal with you, for you abide, and if they likewise were to abide, they would not be time. For what is time? Who could find any quick or easy answer to that? Who could even grasp it in his thought clearly enough to put the matter into words? Yet is there anything to which we refer in conversation with more familiarity, any matter of more common experience, than time? And we know perfectly well what we mean when we speak of it, and understand just as well when we hear someone else refer to it. What, then, is time? If no one asks me, I know; if I want to explain it to someone who asks me, I do not know. I can state with confidence, however, that this much I do know: if nothing passed away there would be no past time; if there was nothing still on its way there would be no future time; and if nothing existed, there would be no present time."
