What's Wrong with Prosperity?
Prosperity is usually a focus on the world exclusively. In other words, works takes a backseat to borderline works. Where your treasure is, there is your heart also.
Then there are reactionaries in the pulpit who poo poo prosperity. The pulpit at one time was popularized by proud paupers. Today however, prosperity preaching is rather prosperous itself. How many millions does a preacher need? That is, needed is to set up a foundation to exemplify works rather than beliefs only? You'd think somebody was reading in James recently.
