Thabiti Anyabwile takes his cue from Mark Dever's What Is a Healthy Church?, which offered a definition of what a healthy church looks like biblically and historically. This companion asks the question from the pew rather than the pulpit: what does a healthy member of such a church actually look like, and how can an ordinary Christian labor for the health of the congregation they belong to?

The marks he sets out are concrete and mostly unglamorous - being an expositional listener, a biblical theologian, gospel-saturated, genuinely committed, a praying member, a willing disciple and discipler, a humble follower of leaders, a giver. Short chapters, written for members rather than staff. Part of the 9Marks series and widely used in membership classes.
