When Dr. Carson spoke at my church, there were around 400 people in the room. He said that you could blindfold a kid, bring them on stage, remove the blindfold for a second. Then, 50 years later they could remember where each person was sitting and what they were wearing - if the full potential/power of the brain could be unleashed. Hard to fathom, but I believe him.
If one could recall, in great detail, every exquisitely sweet moment from the past, that’s where one would live.
I believe that is why the bible doesn’t go into much detail about how wonderful Heaven will be. If we knew, we might be too anxious to get there.
