Ironic statement - Jehovah is going to put an end to all of that. (By murdering billions himself instead)
You are correct, the carrot is very real in their minds, the WT wants it that way. Even recent articles telling the troops to meditate on the paradise shows they want them under that illusion.
One of my fave posters who moved on (LeavingWT) used to say something like this when people would complain about not being to wake up friends/family members (loosely quoting here): "You are competing with everlasting life in a paradise earth, what do you have to offer?"
It really shows how if a person actually believes this is going to happen, you don't stand a chance.
