I once met someone online who fervently believed that only a select few would survive the end of the world (as we know it) and be granted some kind of superlative existence (what this amounted to I was never quite clear on) by an omnipotent superhuman power.
Of course in this case the "superhuman power" was held by the survivors of Atlantis (or their descendants, again, never quite got clarification on that) and being one of the "select few" involved being included on some "list" that was being kept somewhere. And if you weren't on it, well, when the long-gone Atlanteans returned and the world ended, you were SOL.
While I had no problem with her believing that this would all go down as she claimed, and taking some comfort in believing that she was on the list and therefore safe from whatever horrors awaited those who weren't, I drew the line at being expected to take her word for it and "get [my] act together" or else be counted among the damned.
Whether I will retain or regain some kind of individual existence or consciousness or "soul" after this body ceases to function is something over which I have no control and can claim no certitude by any standard that is, to me, acceptable. Whatever happens or doesn't will be a function of how the universe works, and my belief or lack thereof with regard to any theory about how it functions will have absolutely no effect on what actually takes place.
However, from what I can tell based on personal experience and study, the spiritual traditions that do posit some kind of individual existence after the one I'm now enmeshed in all seem to agree that my "status" in the presumed afterlife or next life will hinge on how I conduct myself in this one.
So, from a purely practical perspective, it seems pretty obvious to me that my primary concern should be with how I'm living this life, which is something I actually do have some control over - whether or not the choices I make here and now have "afterlife" ramifications is irrelevant. If they do, so be it. If they don't, then I still did the best I could with the life I had.
