Our experience is the similar to his except we experience nows as a chain of events. We recollect past moments and anticipate future ones while always in the moment. Life and reality happen in that instant. The difference between God and ourselves in this regard is that we have no ability to slip out of the confines of this moment, whereas he always is outside those confines. Even if he "drops" into those moments in order to interact with them, he still is equally present in all our moments (omnitemporal).
When God interacts with that which is in time, he acts according to the convention of time--he is in that moment. Those in time see it as occurring in that moment as part of time and God experiences that moment in time. That does not mean that God ceases to be omniscient nor supertemporal (eternal). It only means that anything in creation experiences that now moment, even if it is only dropping in from outside.
