Hmmm. Russ, the last two links you provided are a bit scary. Here's a link to http://www.tbn.org/. I can't find the program in question. Megiddo is is another name for Armageddon, the location in Israel where the final battle between good and evil is expected to take place. Whenever there's a significant tragedy, the TV evangelists go into a feeding frenzy, talking about Armageddon and all that sensationalistic end-of-the-world stuff. Makes for good TV ratings, and larger collections. If the world is coming to an end, who need soney? Might as well give it to the preacher and buy some salvation.
As a Christian (of the liberal variety), I find television evangelism very embarrassing, for the most part.
