To this day, the idea of Field Serve Us makes me cringe. Isn't it one of the least effective methods of reaching people? Just keep the R&F busy so they think they are doing God's work. Meanwhile, there are millions if not billions of people on this planet who have no idea who they are. And never will. This will always be the case. When I was a teenager back in the 1970s I did the math. The numbers didn't work out then. They still do not. Mathematically, 8 million JWs (?) cannot possibly witness to 8 billion people.
Insanity... doing the same things over and over expecting different results.
