There are several issues which follow from the idea of being patient for the fulfillment of prophecy. Here are two more of them:
The first thing to remember is that real time functioning prophets and those who were called "prophets" were either mad or useless or both. No-one ever gave a "divinely inspired" prophecy which was useful to anyone else.
To believe in prophecy is to declare you have no proper education and that you see the world like a child; chaotic, supernatural and subject to the whims of a spirit world.
If prophecy actually worked then scientists amongst others would use prophets. As it is, prophecies are only broadcast to manipulate the gullible, take for example leaders of cults like the governing body of Jehovah's Witnesses; they know that "Bible prophecy" is their trump card in keeping their membership going. Only a few realize the trick being played on the them. The majority of JWs are unthinking true-believers without the curiosity and courage to question governing body's doctrines and predictions, most of which are absurd and plain wrong and have been proved to be so, as Freddo has pointed out, for parts of three centuries.
Secondly the context of the Biblical "end times prophecy" was only to do with Jews under Roman rule. The Jews like all the ancients, were suckers for supernatural omens and quite blatantly the prophecy (mug's game remember) was just for Jews and just for that generation and none other. Luke 21;32,33 and Mark 9;1
The GB and everyone else should have noted that the Bible got it completely wrong so why continue to put faith in the Bible as a book of prophecy?
