One of the things which has rather surprised the people who study church growth is that many of the churches which are really booming are the ones which ask the most of their members. While we hear a lot about making the church accessible and making worship a "low threshold" experience, what we are seeing is that some people are catching on to the fact that symbolic religion is about as nutritious as a caffeine free diet soft drink... it's cold, it's carbonated, and it's sweet... but there is nothing there.... on a steady diet of it, you will die of starvation.
