Everyone who becomes a witness is attracted a LOT by the fact they "hold the answers".
The society "provide the truth" but folks end up believing the truth is the organization. Pretty soon, there is nothing else on earth and the person that was desperate for something becomes a know-it-all.
Looking now, i wish i'd of realised that anyone holding all the keys and knowing all the answers is clearly wrong. NO ONE KNOWS and no matter what comfort we might get from pretending to know, its easier (eventually) after riding the storm and just being you.
