Time is not a substance. It is the mind's measurement of motion. So to say that something is temporal is to say that it is in motion and undergoing change. Since God is the Unmoved Mover, He is immutable. Thus He is not temporal, but eternal. Further, since time is duration, God does not endure; He is in His eternal now.
One major objection to divine eternality is that God cannot relate to temporal things, because He would need to be temporal in order to do so.
A response to this objection is the understanding that God does not have to be temporal to bring about temporal change. As the Uncaused Cause, He has willed all causes from His eternal now. This is similar to Him setting up a chain of dominoes from eternity. Where and when the dominoes fall is determined by God in His eternal now. He does not have to be moving when they are moving.
