I remember @Sour Grapes' post from a couple of months ago about "world conditions" never being as bad as they are today. @Giordano brought up an interesting quote from Eric Hoffer's book, The True Believer:
"Not only does a mass movement depict the present as mean and miserable - it deliberately makes it so. It fashions a pattern of individual existence that is dour, hard, repressive and dull. It decries pleasures and comforts and extols the rigorous life. It views ordinary enjoyment as trivial or even discreditable, and represents the pursuit of personal happiness as immoral."
I think Watchtower deliberately imposes such uncertainty and instability on its members' lives. You wonder how people continue to put up with it, @silentbuddha, and it's because any other route is conceivably impossible for the Witness. Watchtower keeps its members by baiting them with the offer of certainty of "God's promise". The offer of complete security if you do everything right within the organization... The offer of an impermeable faith that can't give way, should you ignore anything that does get in its way. And in the midst of Watchtower's induced uncertainty on the member's life, this seems like an offer worth holding onto.
I sometimes think of Watchtower's "imminent destruction" theology as a marketing scheme in the same vein as, "hurry now! Offer ends soon." False urgency is created in people and those studying with Jehovah's Witnesses. "Gosh, if I disagree with what I'm being taught, I might miss out on the deal of a lifetime. Better block out the negative aspects and commit to purchase before I miss out!"
