Let me see if I can illustrate:
Someone prophecies that a commercial airliner is going to crash in Europe in 2007.
Not a hell of a lot of use.
If they prophecy the date, that helps more, and then the specific airline, that's a huge plus, and the flight, you're golden. If you avoid that flight, and it crashes, you pay attention after that, eh! If it doesn't, you know that like most prophets, this one if full of shit and not to be taken seriously.
What the WTS does it take some general statement, look back, and say, "See, it applied to TWS Flight 323 to Paris on August 20!"
Well, what in hell good does that do you after the fact?? What value is any prophecy if you can only figure it out after the damn thing has happened?
And thus lies the secret of all prophecy and prophets - make it so general no one can figure it out, but with enough detail that someone somewhere can apply it to something. The Bible prophecies and Nostrodamus are wonderful examples of this kind of bullshit "prophecy." Anyone that believes there is anything to them is a fool.
Give me the prophet that gives day, time and event before it happens, and then we've got something to talk about!
