Typical cult practice - instill fear of some 'catastrophic event' that, unless you are part of the cult you will not live through. They've been wrong on everything else, so it stands to reason they'd be wrong on this too. Since I left, I've done some study on the book of Revelation and read some books by 'secular' authors, and it's interesting how other people view the events of Revelation. (I recommend any of Tim Lahay's books on Revelation.) Most seem to agree that the events of Revelation will be devastating to the earth and those on it, but that it's a time that God will use to bring as many to him as possible. Contrast that to the Witness view that if you're not already 'saved' you're going to die.
My personal feeling is that the 'end of the world', however it plays out, is going to be not as any of us think. The only thing we can do is to do what the Bible says (not the WT) - believe on Jesus Christ as our redeemer, develop a personal relationship w/ him, follow the code of conduct of the Bible (not the WT), and believe that his kind and merciful nature will overcome our deficiencies. Then, regardless of what happens at 'Armageddon', we will have done what the Bible says and therefore should have no fears or worries.
I love how the JW's tell you that, not only do you have to do all their crap, but if you don't do it right you STILL might die at Armageddon. What a crock.
