I'm try to understand what they are calling the prosperity gospel. It seems more of a slur to those who believe what God says, not sure. Abraham, Issac, Jacob, Solomon didn't attain their wealth on their own - as we know it came from God. Joseph is another one and Naomi and Esther.
"But seek first His kingdom and His righteousness, and all these things will be given to you as well." And those mentioned above did that.
GOD FIRST ALL THE TIME. His system is not like the world's. He is Our Source for everything - spiritual, physical, emotional and financial.
Money is needed to spread the gospel and bless others in need which we are called to do. It can leave one suspect who opposes prosperity.
The difference is btwn a balance view which does not make poverty itself a virtue, or mean a lack of faith, nor supposes that gain is Godliness, but believes God to provide as we practice Mt. 6:33, and that faith will be tested, and that we can pray for wealth to be used for His glory, but to be content in either want or in plenty is a mark of maturity, and that sacrificial living is always a practice of the Christ-like.
Paradoxically, it is the typical so-called “faith teachers” that often display lack of faith by the time and energy they put into fund raising by selling the idea that gain is Godliness.
