There's a difference between not wanting to die (esp.violently) and having a desire to live forever and ever. I think we confuse our natural inclination to preserve our own life, with wanting to actually live eternally. Just because we are wired to stay keep ourselves alive doesn't mean we were meant to live forever. Wanting to live forever may just be human greed....more is better.
Animals strive to preserve their own lives even though they have no plans or hopes for the future and supposedly weren't meant to live forever . The difference between them and us in this regard is our level of consciousness. Even small children have no concept of future and past and they have no plans or hopes. It's only later, unlike animals, that their level of consciousness develops to that point.
JW's planted the idea in my mind that eternal life is possible and I should WANT it. Looking back, what I wanted most was NOT to be DESTROYED by God.
They said that it doesn't make sense that God would create humans just to have them grow old and die. Why does it make sense that God would create these intricately designed animals only to have them die of natural causes or be devoured by a predator? What would be the purpose in the new system to have animals cycling through all the time while the humans stayed forever? Wouldn't that cause us sadness to see animals we've grown attached to, die. Imagine having an elephant for 80 years and then having it get old and die.
If anyone lived beyond 100 years even in reasonable health, they might not think living forever was such a great thing. They might just think "enough already". It seems to me that in order for us to be happy living forever, we'd have to be in a more childlike state mentally. Perhaps that state of innocence that would enable us to tolerate living forever, is what Adam and Eve lost for us by eating the forbidden fruit ( if that tale is true).
All I know is so far everyone who has lived so far, has died. That's the way it is. No amount of wishful thinking or study of primitive writings is going to change that. It is what it is.....get used to it. It's quite freeing once you do.
To me it's like the flowers in spring. If they bloomed all year long, they wouldn't be that special. It's because they are here for a short time, that we value them. Having a limit to our lives might make it more precious to us.
