That's the power of a guilty conscience. That's it. The Catholic Church rose to such massive heights due to the power of a guilty conscience; that's how they make their money. It's not wrong to convince someone of guilt if they are guilty, but what's the solution presented to that guilt?
Bob claims "you are robbing God" -- solution? Pay Bob money to be absolved.
That's the fallacy. Look, in the big picture for my own ministry, the amount of Christians who listen to me on a regular basis who have helped out Lorraine and I charitably would be less than 1%, while men like Ed Young complain about having a 20% donation rate as not being enough. However, you don't see me complaining about it, nor do you see me making videos asking people for money. That's because Lorraine and I, though we want to have plenty that we might be able to do many things for others, we're not laboring to be rich.
It's amazing that Creflo has gone from teaching that people should tithe or die, and after a lot of heavy criticism, he has changed to "giving freely," but... he still teaches tithe and he's a hypocrite. If I try to put myself in his shoes, I just don't see how I could sleep at night, not because I'm a good person, but because the Holy Spirit of God would convict me so heavily, I would have to start up orphanages and homeless shelters, and all sorts of other things to alleviate that guilt, and NOT tell people that they need to give me more in the process.
