Where Do You Find Church?

I recently had a conversation with a woman who used to be a church-goer when she was young, but hasn't found herself in a church setting in a while. When I told her I lead worship at a nearby church, she was interested in coming to visit. We in the church have theories about where we go wrong in bringing new faces into our buildings. Out in the world people go about their everyday lives, and we watch to see if they are a part of the church or outside of it.
