A friend, who wishes to remain anonymous (for good reasons which will be evident upon reading the appended message), sent me the following note which provides a very good analysis of what drives Pat Robertson and his followers to say the strange things they regularly say:
As the son of parents who have sent God only knows how many thousands of dollars to Pat Robertson, Jim and Tammy Faye Baker, Jimmy Swaggart and others of their ilk over the years, I have watched these TV preachers -- and their supporters -- with keen interest. You are absolutely correct about Robertson's reckless rhetoric, but it is precisely his willingness to make such statements that brings in the cash.
There is a paradox in people like my parents and other followers of the Robertsons of the world. They are true believers who doubt their beliefs. This is why they glom onto signs and become breathless at the prospect of a prophecy fulfilled. If they truly believed, they would not need constant reassurances and proofs. They are fearful believers -- afraid of God, afraid of Satan, afraid of Death, afraid of Themselves.
Robertson pointed to Sharon's stroke and then to the Bible and said, "See, the Bible said this would happen, and it happened!" It was his way of exciting his base of doubtful believers.
He not only bucked them up by giving them a proof. He also gave them a sense of superiority. They came away from his show believing they have knowledge others do not have, some because they are ignorant and others because they will not see the truth. His listeners believe themselves to be an enlightened elite.
There is a line in Daniel about the King of the North attacking Israel. My mother currently believes the King of the North is Turkey, and she is expecting an attack by Turkey on Israel any time. Over the years the King of the North has also been Iran, Iraq, the Soviet Union, the European Union, and the United Nations.
Pointing out to my mother that predicting attacks on Israel is like predicting cold in winter has no impact on her. Pointing out that she has believed in numerous Kings of the North over the years does nothing to temper her belief now. Each time a new King of the North is identified by Robertson or some other Evangelical preacher, she gets all fired up, and out comes the checkbook.
My parents are also believers in the Rapture (the righteous will go straight to heaven without the inconvenience of dying, and the rest will be left behind to endure seven years of tribulation ending in the battle of Armageddon and the establishment of 1,000 years of Heaven on Earth.) Israel plays a central role in this. Before the Rapture can happen, Israel must be fully established. Anything that holds back Israel holds back the Rapture.
There are plenty of Christians who opposed Sharon because they saw his position regarding the West Bank as holding back the Rapture. An expanding Israel gets them to heaven quicker.
So there really are three reasons for Robertson's remarks regarding Sharon. First, they keep the money flowing. Second, they give believers a feeling of superior knowledge. And third, they are a way of gloating over the destruction of a man whose policies were delaying Jesus' return to Earth.
This is how I see it, anyway.
