Just imagine the WT doctrines, 50 years from now.
All the now GB would have been long gone.
A new set of GB would have arrived, may be Jws who are in their 20’s now.
King of the south would have changed by then.. Even the King of the north
Blood ban would have been lifted.
Same sex marriages would be performed in Kingdom halls.
Women may be elders.
Filed service would have been changed drastically. May be Field service from the comfort of Kingdom halls or homes through some optical Virtual Images.
The only things that wont change would be: Armeggadon is imminent threat, donations and the discouragement to read old WT Publications.
