Fear of the end of the world is jw ' bread and butter.
last time an elder visited me to encourage me to go back he told me ,and i quote :"what if Armageddon comes?"
i think it depends as for myself,since i still believe in god and Jesus i think it will come when God decides.
many here don't believe it anymore and it works for them.
I'm personally trying to get to a point where i'm at peace with myself and the world to the best of my circumstances,that is all that i can control.
after that it's in God's hands....
peace out
