Brothers, We Are Not Professionals – John Piper
Easily the best book I have ever read about being in the ministry. In this book Pastor Piper pleads with his fellow laborers for Christ to stop chasing the latest fad in ministry and to stop trying to be a carbon copy of the latest megachurch. He instead intensely urges us to hide completely behind the cross and have a ministry that is Christ centered and God glorifying. If you are wanting to do a check up on your current ministry and see where you need to draw closer to God, then grab this book soon. But be prepared that you will be challenged and pruned for His Glory.
