Also, Judaism doesn’t “guarantee” life after death. Many Jews are “agnostic” on the afterlife, meaning they believe there’s no way to know what happens after you die. (This is by no means the only view though).
I think what he’s saying is, as we have already lived for some time on earth, we can’t then go someplace else for eternity - some of that time we’ve already used up.
No, I think what he’s saying is that eternity has to go in both directions. If it has a beginning, it’s not an eternity. The Christian conception of eternal life is a “ray” (-------->) rather than a “line” (<-------->).
I don’t know why it can’t be a ray but I think that’s what the OP is saying.
Generally, a difference is made between eternal and immortal. God is eternal (no beginning, no end), the human sould is “only” immortal (a beginning, no end).
Well, there are helpful symbols we can use. Consider the infinitely long line of integers:
-4 … -3, -2, -1, 0, 1, 2, 3 … 4.
One can define a function with asymptotes or discontinuities at, say, -1 and +80 or whatever. I don’t see much of a problem positing something like:
For -4<x<0, x=non existence.
For 0<x<80, x=physical life
For 80<x<4, x=afterlife.
Now, modern cosmology suggests that 13.7 Billion years is all the time there is in that direction, ie. that for -4<x<-13.7Bn / x=-13.7Bn where x is the configuration of the universe,
and I have no idea why one would distinguish the nature of the afterlife from that of the beforelife since I consider it pretty obvious that “we” were and will be simply a disparate arrangement of atoms outside of the physical life bounds (ie. when we weren’t concieved or when we’re dead). But I don’t think it illogical to posit such discontinuities in general.
It’s a simple definitional problem, nothing to get worked up about. “Eternal” is being used, perhaps carelessly, in two ways – that of an event which starts from a point and then continues forever; and of an event which exists outside of time and which those of us of temporal existence, were we to observe it, thing has no beginning and no end.
When people speak of god as being eternal, they’re using the first definition; when they speak of souls having eternal life, they’re using the second.
You are already in an eternal stream. Every molecule, every atom of your body has been recycled again and again since the beginning of time, and will continue to be recycled until the universe is cold. And it will exist forever after that.
“I” am neither. “I” am the unique string of memories encoded in my neural structure. I am not the atoms themselves but their arrangement. When I die, that arrangement becomes disparate and the memories are lost to entropy (ie. become indistinguishable from noise), just like throwing a hard drive on a bonfire.
Lifting me up where the eagles cry on a mountain high? Sorry, I’m afraid I suffer from a completely rational fear of aviationally metaphoric ballads.
