It is hard to believe that the organization is dying. I think, more likely, it is becoming increasingly less relevant, even to current JW's. People are going through the motions. The talks are taking on a end-of-the-world vibe like they did pre-75.
A couple weeks ago, the CO visited and his talk was about the destruction of Noahs day and Sodom and Gomorrah. "These are a pattern" and "if they happened back then, the end is surely coming and millions perhaps BILLIONS will be destroyed wiped out....will YOU be among them?"
I almost gagged. Then, in his final talk, he talked about how God is an optimist, but the devil is a pessimist. I guess destroying a BILLION people is the optimistic thing to do.
As for growth in 3rd world, well fear mongering still works over there. Life is hard. It is easy to manipulate people and promise them something better. Many are uneducated. Many are looking for connections, social connections, to improve their situations. In time, they will see that it is a sham...just like many here have.
