Well, I know it's 100 years since Jesus did his invisible stuff in the sky. Or if you read the back of the new JW bible I believe it says 'about 1914'.
I spoke to a JW recently (one that still speaks to me), and I mentioned it's 100 years now and their smiley reply was: 'So what does 100 years have to do with it? It doesn't matter, we don't serve for a date.'
That's it isn't it?! The JWs have their 'overlapping generations(tm)' and 'About 1914(tm)' so they can rest easy in their warm and cozy delusion.
Why should 100 years be significant to them anyway? ('anyways'....for my cousins across the pond )
