One day while out in Field Service with the smartest brother at our Kingdom Hall, a long time Elder and an extremely dedicated man, I asked him if he understood the overlapping generation dogma, and could explain it to me. (He was driving, I was riding "shotgun", and there were two Sisters in the back seat).
He was very thoughtful, for a few moments, and replied "I think they are trying to do the best they can ...."
He could not explain it to me.
Perhaps he needed to see this video!
It's so CLEAR to me now!
