Herbert Armstrong wrote a lot of booklets which made promises — actual and implied. When we go back through and review the booklets he and his staff wrote in the light of what has actually happened, it is clear that the great swelling promises and prognostications were profoundly empty. Looking back, the booklets now seem crassly hypocritical. The Radio Church of God, Herbert Armstrong and the Worldwide Church of God never measured up to the very standards they set.
It takes all types, but people will usually listen to anyone who speaks, or yells loud enough, with any kind of authority. Sometimes, this can be good if the info is profitable to the listener, but at other times it can be a disaster. And this can reveal a BIG difference between a guru and a proper teacher.
