The letter of 2 Corinthians is important, Paul Barnett believes, for its magnificent message that God's power is brought to people in their weakness, not in human strength. This momentous theme emerges in a dramatic real-life situation. The apostle confronts shadowy opponents who had recently come to Corinth and formed an alliance with some of the church leaders and members. His letter is a fascinating record of that conflict. His aim in this exposition has been to allow the timely message of 'God's fool' to be clearly heard.
