"Maybe they've discovered how lucrative televangelism can be. Just keep listening to us and sending us your money and we'll give you all the tools you need to survive Armageddon"
I remember the old Hour of Power and similar shows offering a "free gift" for donations above a certain amount. It might be one of Robert Shuller's books, or some "inspirational" frippery with some "possibility thinking" message. If the GB started being less judgemental on the outside world and started writing more "inspirational" stuff (and got a charismatic front man), they could perhaps pull off something similar. If the sales tax issue doesn't stop them from doing it, that is.
