We knew a brother from Florida who did a really nice talk about young people, Used two slide projectors and hundreds and hundreds of slides. That was many years ago when one could still give talks on any subject without an outline from Brooklyn. I must admit that that talk was the best one we ever saw and it was not from Brooklyn. Eventually the CIA at Brooklyn put a stop to all made up talks, now only outlines from Brooklyn are used. Some of them are terrinle.
The congregations could benefit from some forward thinking teaching programs not the drival that is still being thrown around, teaching the way they have for a hundred years. Bring back some good slide presentations, use videos, overhead projectors, etc. Teach not spew words.
