This is unironically the type of preaching that megachurch pastors use to incentivize people to donate. It’s called prosperity gospel. Basically, it’s the belief that God rewards his most devout followers with material wealth. So if you’re not rich, it’s because you’re not a good enough follower and need to keep donating. It’s what pastors like Joel Osteen and Kenneth Copeland use, to get their followers to buy them new private jets.
