Bible (KJV) NT 08: 2 Corinthians

The Second Epistle of Paul to the Corinthians, often referred to as Second Corinthians (and written as 2 Corinthians), is the eighth book of the New Testament. The letter, originally written in Koine Greek, is from Paul of Tarsus (and Timothy) to the Christians of Corinth, Greece.

Paul defends his authority as an apostle. He also states the importance of forgiving others, and God's new agreement that comes from the Spirit of the living God (2 Cor. 3:3), and the importance of being a person of Christ and giving generously to God's people in Jerusalem, and ends with his own experience of how God changed his life.
