We are being formed by these economic structures that have taken over our social worlds. The practice of tithing on credit - with money you don't have - betting on some future return, is a form of speculative faith. In a way, Christianity has done that for a really long time, I don't think it's something entirely specific to prosperity Christianity. What's specific about these kinds of prosperity Christians is that they were using credit cards, that there was a financialization of faith.
