As is quoted from the article:
"it seems that Jehovah will re-create people "
So, the resurrected have to be re created. In that case they are not the same people. Just new people that look like someone who lived before, are implanted with their memories. ..but it is not them.
Without a belief in a human soul this doctrine falls down. E.g.
If I were to back up all the files and stuff on my PC, then dump it and buy a new model ....I could have all the info loaded on the new one. I would then have a new computerthat " knew" everything my old one did . It may do everything my old one did, but would it be the same computer? No.
Perhaps I am missing the point but since "waking up" to things this doctrine has not made sense.....
