Book excerpt: We live in a time when leadership and showmanship are seen as far greater virtues than humility and meekness. Even the church has often got it backward. And in Paul's second letter to the Corinthians, he confronts similar problems in the first-century church. D. A. Carson believes we can learn valuable lessons from Paul's letter about what it really means to be a mature Christian in the face of adversity. In A Model of Christian Maturity he takes the reader step by step through an exposition of 2 Corinthians 10-13 and then helps them apply these Scriptures to everyday life in the church. Perfect for pastors, students, and laypeople, this book highlights the power of weakness in the life of the Christian.
