Just my $.02. God is eternal, no past, no future. Therefore God can exist in only one moment in time, the eternal present moment. All existence is present to God in this given moment. As to how it will relate to us, I really don’t know. I like to think I’ll be able to experience every moment of my life here on earth, and every moment in his presence (God willing) to come. God’s time is a difficult concept to wrap the finite mind around.
Edited to add: I do think it is an important concept though. We can only live in God’s love, light, and law in this moment. We can’t say to Him, I’m going to do what I want, regardless of how You feel, but in a couple years, I’ll do things Your way. That doesn’t work. And the flip side is, if we embrace the sacrament of reconciliation, those sins of our past, are not present to God’s mind. We are forgiven and rate eternal life with him. One moment at a time.
