It has always amused me that most people who fervently accept the concept of an everlasting, immortal soul are just as fervently OPPOSED to the possibility that said immortal soul could be re-assigned a subsequent gig by a God through whom all things are possible... not that I’m in a big hurry to verify it... :)
I figure God has it all planned pretty well, and my job is to live any current life as well as I can. These things are fascinating to think about and even study; they suggest all sorts of possibilities and can lead to a lot of interesting conjecture.
But that doesn’t change the fact that we have to live here, now.
Well, Christians are opposed to the notion because the New Testament rules it out in no uncertain terms:
“...it is appointed unto men once to die, but after this the judgment” Hebrews 9:27
