Something to note :
A study last year may lend some credence to the legend. In “Praying for Recession: The Business Cycle and Protestant Religiosity in the United States,” David Beckworth, an assistant professor of economics at Texas State University, looked at long-established trend lines showing the growth of evangelical congregations and the decline of mainline churches and found a more telling detail: During each recession cycle between 1968 and 2004, the rate of growth in evangelical churches jumped by 50 percent. By comparison, mainline Protestant churches continued their decline during recessions, though a bit more slowly.
The little-noticed study began receiving attention from some preachers in September, when the stock market began its free fall. With the swelling attendance they were seeing, and a sense that worldwide calamities come along only once in an evangelist’s lifetime, the study has encouraged some to think big.
But...but...but I thought the number of Christians was SHRINKING?
