Can any of the facts about Dave MacPherson in the article posted by CynicalBear be factually disputed?
In the article, Thomas Ice bases his attack of MacPherson on trying to dispute MacPherson's exposure of Margaret Macdonald, the teenage mystic who's dream-vision gave John Darby the idea of the pre-trib rapture. MacPherson exposes Thomas Ice as a fraud by proving Ice's falsification of the text from Margaret Macdonald: http://poweredbychrist.com/Thomas_Ice_Bloopers.html
Here, MacPherson refutes Ice's points by showing that Darby did get his ideas from the mystic Macdonald. http://poweredbychrist.com/files/articles/Strandberg.htm
