If time doesn’t exist in heaven then it would seem hard to make sense of lines such as “The angel of the Lord called to Abraham from heaven a second time” (Gen 22:15) or “At that moment heaven was opened” (Matt 3:16). And how could we experience anything changelessly?
John 17:3, of course, defines eternal life simply as knowing God.
I was hoping a philosopher or theologian has tackled these kinds of question in depth.
Picture a child’s rubber balloon and an ant.
Originally the balloon was very tiny. In fact the balloon was so tiny that the ant could stand on the balloon and touch all places on it at once. The ant didn’t need to move to do so. He was simply “there.”
Then the Breath of God inflated the balloon. Suddenly it went from teensy-tiny to huge. No longer was the ant everyplace at once on the balloon, and he started scurrying frantically around the outside of the balloon to touch as many places as he could.
God, of course, was not constrained by the enormous size of the balloon. God reached out and touched the balloon in several spots.
As the ant scurried along he encountered God HERE, and then THERE, and then OVER THERE he encountered God for quite some distance because God’s finger touched a large expanse of the balloon.
From the ant’s point he encountered God once, then a second time, then a third time when he had God with him for quite a while.
From God’s point of view He merely touched several spots all at once.
God, of course, is God. The ant is you. The balloon is the universe, and the perimeter of the balloon is Time. The ant is traveling the perimeter of the balloon, across time. God is everywhere along time, all at once. But since all the ant’s perspective is limited to his own movement, he describes his encounters with God as “He called me once, then He called me again, then He walked with me for a long while.”
I realize this is a crude, childish analogy, and overly simplistic. Still, I hope it helps.
