If his daughter dropped down dead he has double reason to hang on to the resurrection belief. He is emotionally in at age 77 because he looks down the twin barrels of his own coming demise and his daughter's previous one ...
He has been cast aside by the organizaton that used up every last drop of his energy and zeal and he enjoyed the ride and adulation. That's on one level.
On another level both he and their end time prophecies have simply run out of time.
