I agree that a Christian should stay alert. The problem as already mentioned is that the Lookout ( GBFDS ) decided that it was not enough to stay alert. The lookout decided to authorize themselves to execute any of the villagers who pointed out their false alarms. The lookout became a legend in their own mind. So when a honest villager went and investigated the wisp of smoke and found it to be an smoldering camp fire and not the start of a conflagration as the lookout claimed, then the lookout murdered him.
With each kill the lookout learned that the best way to escaper criticism was to kill any villagers that dared to point out his mistakes. At the same time he statred a propaganda campaign to remind the villagers that all their lives depended upon complete and unquestioning loyalty to the lookout. He had saved them from countless disasters that they were not even qualified to recognize! He even forbid the villagers to investigate any wisps of smoke by confining them to the village for their own safety. Any questions about wisps of smoke must be answered from the lookout himself.
Through slick political scheming the lookout had himself appointed as King over the village! Now King Lookout overlaid his tower with ivory! All wisps of smoke were disseminated from the King through his Generals for the villagers. They were only too happy to work in the fields for the Great King Lookout. After all, his unfailing vision kept their village safe from harm. Parents would tell their small children about the Great King Lookout while tucking them in bed every night. If they were good then when they grew up they could serve the King as well!
From time to time a villager would disobey and investigate a wisp of smoke. They would be swiftly punished until they understood the wisdom of the King. For those who went so far as to openly dispute the Kings predictions a swift death or exile was meted out. By making a public example of all dissenters the villagers were reminded of how they were dependent on King Lookout for life itself. All felt safe and secure inside the village..
