Sometimes these "prophets" get their reputation by predicting 1,000 things. When 10 come true, those are touted as miraculous while the the failed 990 are quietly swept under the rug. In other words, anyone can be a prophet simply by making enough predictions.

I haven't looked into Kim Clement at all, but that would the first thing I'd want to see. What things did he (she?) predict that turned out to be wildly and completely inaccurate.
