Book excerpt: The church is experiencing a leadership crisis. What can we do to prevent pastors from leaving the ministry? For every celebrity pastor exiting the ministry in the spotlight, there are many more lesser-known pastors leaving in the shadows. Pastor and best-selling author Paul David Tripp argues that lurking behind every pastoral failure is the lack of a strong leadership community. Tripp draws on his decades of ministry experience to give churches twelve gospel principles necessary to combat this leadership crisis. Each of these principles, built upon characteristics such as humility, dependency, and accountability, will enable new and experienced leaders alike to focus their attention on the ultimate leadership model: the gospel.
