Do you think JWs believe they will never die at all and will, in their lifetime, be on a Paradise earth to live forever?
It seems to me this is a twofold question involving JWs' views of (1) their own standing and (2) the timing of the end.
1. Since JWs have no assurance of salvation and many feel unworthy and even worthless, I think at most they HOPE for this...
2. Newer ones may believe the paradise earth is coming any day now, but I would think that older ones who were told they would never grow old in this system (especially those who remember the 1975 hype) are pretty skeptical of the timing, even if they believe the basic paradise earth teachings.
Although there is always talk about how awful world conditions are and how near the end must be, I don't think very many are quitting their jobs and selling their homes in order to pioneer in the remaining "months" before Armageddon, as happened in the early 70s.
In fact, that might be a good point to raise with a JW who keeps saying how close the end is... asking them if they really believe it why they aren't giving up everything and going d2d full time. If they say, "Well, we don't know Jehovah's timing for certain," we can say, "Right, so why talk about it as if you did?"
