Let me see:
more Kingdom halls = more growth (Jah's blessing)
less Kingdom halls = less growth (no blessing)
It should be simple for the JW to see this, no?
According to what I was taught as a JW, when the end is near it is expected that their numbers dwindle. According to them that's one of the major signs of the great tribulation about to get started. In fact, they justify killing all the people in the planet by their Jehovah, precisely because there aren't supposed to be any people left in the planet worth saving. Hence, having less KHs and congregations is supposed to be a good thing, as it's supposed to be a great sign of their "paradise" being around the corner.
Yet what I see are desperate attempts and adjustments for them to continue looking like they are growing, and attempts at them continue making money. Those things prove to me (not that i need any proof) that what they teach is just nonsense.
