Scully, I never thought about it that way before... thanks for giving me a new perspective on it. I always thought the idea was that if they remained faithful, maybe one day God would let them eat of the tree of life (the 2nd tree) and they would live forever. But I never believed they were automatically living forever. They ate of the tree of knowledge and then they were dying for sure.... but without partaking of the tree of life it seems like death would have come anyway.
The idea of putting out 2 trees and then telling them not to touch them or eat from them also seems a bit bizarre. Have a child and tell them not to eat these cupcakes and leave them there day after day, I betcha they eat them and I don't think your child would be evil for doing so, just curious.
As for Revelations, that whole book is cracked. Sprit beings might live forever but that's a whole different subject.
