I'm bumping this old thread for the active lurkers out there (I was about to make a new one but did a search first).
According to JWs, no creature has a soul separate from the body, and so, everything you are is currently contained physically in you.
Even though Jehovah would 'remember' every tiny detail of you, the preservation of your personality etc. wouldn't be done by supernatural means (excepting that Jehovah himself is supernatural). Meaning that since a continuous 'soul' which is you does not exist, only the memory of who you were would be implanted into a new body. Which is more like the copying of a computer disk than a supernatural event.
The resulting 'resurrectee' would be a clone, not the same person. *
As VM44 pointed out; If He resurrected a new body and implanted it with your personality etc. now, so that there were suddenly two of you - would you agree to be put to death so that the "resurrected" you could live on? Would you believe that the resurrected version of you standing next to you was in fact you, even though you were now two separate people?
That may sound ludicrous and wildly hypothetical, but actually - only time separates the you of now, with the resurrected you of the future new system. So if the process happened now, or fifty years from now (for the sake of argument, let's say the new system is here then) wouldn't matter, for this example.
Something to ponder.
Or is there a logical explanation you'd like to share?
* one could argue that we even now are not the same that we were earlier in life because of cell renewal (as was mentioned already in this thread), but as each cell has been changed while the rest of the "machinery" as a whole was still operating, there was a continuity all the way and the personality etc. was always intact and preserved in you. A resurrection would mean a sudden appearance of a new body imprinted with the 'memory' of who you were. This would be nice for your clone, and the clone would think he/she was you, but in reality, you'd be just as dead.
