Prosperity preachers are, in my opinion, the cockroaches of the clergy. Many of them (perhaps most) preach a polluted Gospel and a twisted view of God. The bring immeasurable disrepute upon the testimony of Christ’s church and run completely counter to Paul’s consistent testimony that he would not “profit” from the Gospel. I do not begrudge a decent living for men like those mentioned in these articles, nor do I resent them benefiting from their own books and other materials. What I do abhor is the way they have fouled the message of Scripture with their teachings that dumb down the Gospel, ignore the holiness of God, abuse people into thinking that “faith = prosperity” and the superficiality of their theology (in comparison to the sophistication of their business acumen.) God is far more interested in our holiness than He is our happiness.
These articles (particularly the one on Osteen) are rife with sarcasm and bias, but sometimes it is possible to learn more from critics than sycophants.
