God's Glorious Church, The Mystery and Mission of the Body of Christ by Tony Evans and published by Moody Press.
Do you see the church as a building? You're not looking high enough. As a denomination? You're not looking wide enough. As the sum total of all Christians? You're not looking deep enough. Dr. Tony Evans shows how the church is nothing less than the ongoing incarnation of Christ on earth--a living body with a mission, a purpose, and an ultimate call to disciple the whole world. Verse by verse, Tony Evans explores what Jesus really meant when He said, "On this rock I will build my church." And why you, no less than the apostle Peter, are one of the living stones that make up the mysterious structure that is the church today. You'll discover the church's mandate in the Great Commission and come to definitive conclusions about how it should be organized and what it should be trying to achieve.
