Churches can easily bring together, in a short period of time, a substantial number of people, and politicians have to assume that these folks have the potential to vote. Although there's supposed to be a separation of church and state, they want to go to these churches to say hello to the people, and they assume their hello might turn into votes.

So long as there's been black churches in the United States, there's been a relationship between spiritual well-being and material acquisition. This has always been the case.

The key figure in the Christian faith involves a story of suffering so that others do well. You're only going to get so much liberation, you're only going to get so much transformation, from a system that is based on suffering.

You get a sense that it's okay to have good stuff and still claim a relationship with God. So enslaved Africans rethought their predicament in a way that entailed getting good stuff, material stuff, and having a deep relationship with God. There was no contradiction. And the idea just moves forward from there.

The problem is poverty. And it hides the problem. We often associate black churches with a history of protest. But prosperity gospel and megachurches tend to be rather soft on political issues. T.D. Jakes doesn't take a major stand on political issues. Creflo Dollar certainly doesn't.

The ministers argue that within the context of scripture there's a requirement given by God that you've got to give ten percent of your income to the church. And if you give ten percent - here's the hook - God is going to reward your faithfulness by giving you that ten percent back, and a whole lot more.

The American Dream has really good PR. It's kind of difficult to live in the United States and not on some level be pulled into the allure of the American Dream. It's in the DNA of the country. So, for a population coming out of slavery, desperate to become part of the full life of the United States, it only makes sense that they would embrace this route to the American Dream.
