Ministerial training school.... intellectual???
Even as a believer I'd never have thought that🤣I was always bored witless with the repetition. It's quite obvious you're never going to learn more than the rote 50 or so scriptures they teach....if they did, people would likely wake up. They have to keep you locked inside the school for dummies.
There's not likely to be anything new up their sleeves in terms of Biblical teaching on these courses. If there were the ordinary JW, as the foot soldier who does all the converting, would need to know it the most. This is why (unless you are very new) an elder is never going to have anything for you other than meeting/pray/ministry.....if anyone needs to metaphorically "unlock the keys to the kingdom" it's the regular publisher who makes the converts.
