A new book that I’m looking forward to reading is by Thabiti Anyabwile called What is a Healthy Church Member?  Here is a book description from the publisher:

For Christians, playing an active part in the local church is not optional. God intends for every believer to contribute to the mission of the local church and experience profound spiritual growth as a result. This book shows church members, pastors, and church leaders what a healthy church member looks like.  Biblically and practically instructs church members in ways they can labor for the health of their church.

Also, Michael Dewalt interviews Thabiti concerning the book here.
