Well, you are shortly going to be able to discuss this all with Jesus, and explain to Him how much discontent the prosperity gospel sowed. All that effort, and not a single soul was saved. 35,000 people in one church and not a Christian among them. Such a waste.
35,000 and you can’t guarantee that they are all saved either.
Putting your trust in someone named Jesus who is not the One from the Gospels will get you nowhere.
If they are using Jesus for the prosperity angle, for what they can get out of Him, I do indeed question their salvation.
