Second Corinthians is the most personal and complex of all Paul's letters, briming with passionate self-defense and intensity of his concern for the church's eternal destiny. Scott J. Hafeman reconciles three elements to one another to give an understanding of Paul's second letter to the Corinthians: weakness, sufficiency, and the Holy Spirit. The weakness is Paul's personaly ability to succeed, the sufficiency is the fact that Paul does succeed, in spite of his weakness and the Holy Spirit is the power that enables this sufficiency in spite of weakness to occur.
