Hi all,
I do not, in all honesty, have any idea about hell. As for Heaven, I believe it's the same as eternity in harmony. Kind of like two sounds that form a perfect harmony with each other and last forever (in the case of Heaven, one sound is God and the other is a saved person).
Of course, our earthly ideas about pleasure, happiness, bliss, learning more and more, eating delicious food, seeing your children grow, etc., do not apply to Heaven, because all those ideas refer to something that occurs in space in time. Heaven, on the other hand, is the same as Eternity and, therefore, has neither space nor time.
Best wishes,
Richard
