We arrived at the church of the Black Madonna like most tourists, by bus. To enter we walked through droves of trinket and souvenir sellers. Inside people were praying. It reminded us of the money changers in the temple that Christ drove out (John 2:13-25). Surely we don't have such things in today’s world do we? It was years later that I entered a church to hear a famous evangelist speak. In the back were tables with copies of his books on it and a portable credit card machine. I have seen more money-making ministries since. One church even had a permanent store built in the entryway of the sanctuary where they sold audio and video copies of their sermons and books. By contrast, I have visited many churches where prayer is the genuine focus. There is a difference.
