Check out Mark Driscoll's take on the different types of church goers from his book Confessions of a Reformission Rev. See if you recognize yourself in one of these three descriptions.
"Observers were happy to do and give nothing but just came to watch the show each week, not unlike people who hit the brakes when driving past a nasty car wreck to gaze and grin. Consumers likewise gave and did nothing but were always wanting more and making demands for more goods and services from me (the pastor). Participants were the handful of people who had bought into the idea of the church being a missionary to our city. They came to church seeking a way to serve a greater mission and were enormously encouraging."
I think these three definitions of church goers rings true in just about every church. If you go to church, try to see which one you are and maybe that recognition will help move you to being a participant if you arn't already.
