Given that the WT teaches that the dead will know nothing until the resurrection, imagine a resurrected person who died in 1924, expecting the resurrection in 1925 because Rutherford said so in "Millions".
They get resurrected and meet someone who died in 1974, expecting the resurrection in 1975 because Freddy said it was an appropriate time for Jehovah to act.
They meet a JW who died in 1994, expecting the resurrection to come before 2000 because the new system would surely come before the end of the 20th century because the Awake! masthead said so.
Then they meet someone who died in 2014 (100 years after 1914) and learn about Splane's talk about "overlapping generations."
In fact, imagine all the conflicting false teachings each one would be believing because it was "the truth" when they died.
What doctrines would they have in common?
They'd all have to relearn everything, and they'd find out that most of what they proclaimed as truth door-to-door was just plain wrong.
