Paul proceeded to explain further the nature of ministry under the New Covenant so his readers would understand his ministry and theirs better. The nature of Christianity is paradoxical. Second Corinthians explains more of these paradoxes than any other New Testament book. [source][source][source]
In writing this epistle Paul wanted his readers to realize that his ministry was not faulty, as his critics charged, but that it was solidly within the will of God. To do this he described his own ministry as a projection or extension of Jesus" ministry. As Jesus had died and been raised, Paul was similarly dying, but he was also experiencing the benefits of resurrection. He used the death and resurrection of Jesus metaphorically to describe his own ministry. This becomes most evident in 2 Corinthians 4:7-15, but also in 2 Corinthians 5:14-21 and in chapters8-9 where the metaphor describes the ministry of giving. [1][source]
