Yes, I know all about false prophecies, spent from 1990 to 2001 running from them. Every few years, a new fad would begin, and the righteous would flock, like excited sheep, to hear the latest speaker. And, when prophecies failed, there were often disclaimers.
For instance, Paul Cain prophecied that revival would come to England by a specific date in 1991. It didn't. Disclaimer - he said, tokens of revival (small trickles here and there). But he told Wimber that he meant churches would be renewed and the land, revived. Therefore, he - and the other Kansas City Prophets - were either dishonest, or sincere but deluded.
I've noticed that when people become obsessed with the next "great move of God", there's no point arguing with them. It's like talking to a preprogrammed robot.
