It ain’t that hard. One of my uncles did it in the 1980s. He convinced a few dozen people Jeezus was returning anydaynow. They sold all their possessions and waited in his house for two weeks. Jeezus never showed up. The only reason he didn’t get his ass sued is because they first thing they teach in lawyer school is never sue anyone who doesn’t have any money.
Sounds like good advice. Although, didn’t he have all of THEIR money? Even if they did sue, he could have gotten a high priced lawyer with his newly discovered Jesus fund.
