Not too long ago a new kingdom hall was built in Bury, near where I live. It is frequented by two congregations, Whitefield and Bury. Both have problems and are losing members (let's face it, with my family alone Whitefield lost 5 ).
The point is, why is Watchtower constructing new kingdom halls ANYWHERE if the new system is so close?
When I attended the book study we were often told that when the great tribulation occurred the kingdom halls would be shut down and we'd have to meet at a book study - and that if you didn't attend the book study that night you'd miss hearing where the next book study was to be held because they didn't want to hold it at the same house every week so that the authorities wouldn't know and, therefore, arrest and ill-treat the JWs. This, of course, scared the pants off everyone in book study group - so it was a good ploy!
The point is, having kingdom halls is advertising to the authorities where the JWs are going to be every Sunday and Thursday. It's not as if the authorities, if they were hell-bent on attacking JWs, would advertise the fact thay they were coming on such and such a day! They'd do it in secret so as to catch the ringleaders, especially. (YEAH!!).
So, why is it the membership can't work this all out for themselves? Oh, sorry, many are, that's why they're here!
