Are the Harbingers merely meaningless Coincidences?

Near the beginning of his book critiquing The Harbinger, David James has a short section on Coincidences, intending to suggest that even the most uncanny coincidences aren't to be taken seriously, of course implying that's also true of the harbingers of judgment, that they are merely the same sort of meaningless coincidences.

He gives two main examples of extremely uncanny coincidences.  The first was the uncanny correspondences between the Presidencies of Lincoln and Kennedy exactly a hundred years apart, including the names of their Vice Presidents, secretaries and details about their assassinations. 

The other was a novel written fourteen years before the Titanic disaster, which describes an almost identical sinking of an almost identical ship and it was called The Wreck of the Titan. 

There is no doubt that those are two examples of extremely uncanny coincidences that are clearly without any useful import.  All you can do is say "Wow, that's amazing" but also "What's the point?"

But the problem in comparing this kind of coincidence with the harbingers, which so uncannily correspond with a verse in the Old Testament, is that these are not meaningless useless coincidences but highly charged with meaning that carries the weight of the Bible and God's warnings of judgment on a nation and even without them the Bible verse clearly describes America after 9/11.  We're clearly being given a warning and the harbingers set it in stone as it were.
