Interesting analysis. I always wonder about prophecy, though. If the people in the time of the prophecy can understand it, wouldn’t they change their behavior and thus alter the chain of events? It is compelling, though, so I’ll mark this site for some more reading later.
Though, I think we can take courage in what happened to Nineveh. They changed after Jonah warned them of their impending destruction and staved off judgment, but eventually God had to judge them accordingly.
Good thoughts though.
