Evangelicals are good and maybe getting better at talking about the Christian mind, the Christian heart, even the Christian hands and feet. We want to think, feel, and act as Christians. But what about the skeleton? No one really talks about that. If a skeleton holds things together, what is the structure that holds the Christian life together and gives it its shape?

That brings us to this episode of the 9Marks' "Polity is Kool Show." Today we turn to the theme of church membership. And, boy, do we have a show for you. Several brothers give us a biblical, historical, and sociological look. Several more of us consider the importance of membership. And then a few more offer wise pastoral advice on implementing membership in your church.
