I agree but what I understand the prosperity gospel preaching is not the same as what you are advocating.
The prosperity gospel thinking seems to come with a hefty does of entitlement mentality. That God owes it to us by virtue of the fact that the believer is His child and all we have to do is have the faith for it and its ours.
Being responsible, good stewards of our resources and prospering by that is not the same as far as I can see.
When the real persecution hits the U.S. the prosperity churches will fall away.
