The brutal truth is not much is known about eternal life in the here after. The Bible has some clues but I don’t find them at all comforting.
To begin with everybody’s personality is wiped. Memory too is wiped, so no-one need fret about the fate of unsaved family members and beloved friends. Heaven is sound proof to the screams of the eternally punished and constantly ventilated to prevent the whiff of burnt flesh pervading the halls of heaven.
With memories wiped, personalities, hopes, plans, expectations are gone too. Psalm 146:4 “His breath goeth forth, he returneth to his earth; in that very day his thoughts perish.” KJV
There is nothing to suggest any freedom to do what you want in heaven. I don’t recall any offers to oversee individually conferred planets. Chances are, along with personality you won’t have any ambition, curiosity or sense of humour. Science? History? The natural universe is gone. Heaven, Hell or Oblivion are the only things that exist. Academic studies simply won’t be relevant anymore in the afterlife, not even as hobbies.
Mindless, personality deprived, otherwise dis-interested zombies will populate heaven, with the one overriding deliriously satisfying compulsion to worship at the throne of God Almighty for eternity with the same passion the undead have for human brains.
There doesn’t appear to be any other option according the bible. The only other possibility is the vision found in old JW or LDS pamphlets that show happy men in business suits, smiling women in twin sets, high heels and pearls and permanently coiffured bee hive hairstyles watching on as their delightful children play cleanly in sub tropical paradise gardens amongst precious frolicking little lambs and the contented lions who lie down peacefully with them as flocks and flocks of doves fly overhead…I don’t think I could last a day in either place…roll on oblivion.
