As god of this website, I’ll take advantage of my ability to post in the big box. T…ahem, Kami, I agree with you, and thanks for the book recommendation.
One’s concept of god/God defines many things, including whether (s)he/it has an existence that may have a definite start and/or a definite end. It’s all just a matter of word definition (as are many things), specifically, “God”, “exist”, “die”… Different religions and individuals apply different meanings to the words. The Greek/Roman little-’g’ gods were just powerful beings with superhuman abilities, born and capable of death. Jesus was born and killed, but Christians would probably argue that it was only his earthly presence that ended and that his spirit still lives. In which case, what does it mean for any of us to die, then, if only the body dies and yet the soul lives on? Depends on how you define your own existence, and apparently in this case death just means physical death. Can one’s soul die, as well? What, exactly, is a soul and what is carried with it?
Is God a timeless being which created the universe? Then there can’t be a concept of death in God, because death is something that happens in time. Is God the framework in which the universe exists? Is God the universe itself? Nature? The laws of nature? The Force? Are The Gods a powerful race of alien masters who tell us what to do? You laugh (or groan), but the Greco-Roman gods mostly fit that mold.
So as you see, I have many questions, and few answers. I think that’s a good start. Or maybe… maybe I do have all the answers, and I’m just keeping them to myself. Yes, that’s it.
