As Blondie's exerpts show, the jw org vacillates quite often on what's really needed to make a disciple.
Back when the Knowledge book came out, I remember how pioneers and others who conducted home bible studies were struggling to finish one chapter each week, after big emphasis was put on practically racing through the book with the student. This led to further service meeting parts which were aimed at demonstrating how the book was to be studied, as the WTS seemed to try to adjust their ill-fated bible study program. This super-express (and later express-lite) method never seemed to sit well with the congregation. One could sense that in actual practice, what we were being told was impractical. Some jws even joked that it seemed like the Society couldn't make up its mind. Basically, we were expected to make jw disciples out of people who barely would have a chance to ask questions and who not be able to benefit from any outside research.
