>>17897101 (OP)It's modern day paganism. A bunch of loosely connected temples who have some shared beliefs and scripture. They believe piety is rewarded with material wealth and who think anything negative happening in life is the result of them upsetting their god. Giving away money to their pastor is the modern day equivalent of sacrificing your healthiest calf to Zeus.
I do think this sort of religion will come to an end within our lifetime, however. Support for Israel is lower than its ever been and its likely future evangelical groups will focus on keeping members rather than trying to parade their piety since their supply of money will only get smaller.
