Prophecy

Contrary to our way of looking at things, most prophetic statements have not been very specific; they have held little specific detail. They are big on sound and fury and painting large pictures of casts of  thousands of Assyrians coming down on the flocks, but don't spend a lot of time on what Asshurbanipal had for breakfast that auspicious day.

In fact, the more detail the worse it would  be, for it would be forgotten! People would believe what they wanted, having not made the effort to recall whatever the detailed Jeremiah told them, and it would all be for nought.

One of the few times details worked to move men was when Jesus wrote in the sand.....
and even that was not a forecast but a history of the sins of his auditors.
