Second Corinthians plunges the modern reader back to the real, tumultuous of early Christianity. The simple ideals of sharing and goodwill described in Acts 2:42-47 seem to have little place among the diverse converts from this boomtown of Corinth where Paul chooses to anchor his Greek mission.
Second Corinthians is in part a letter of joy, for a report came to Paul that the Corinthians had rejected the troublemakers and wished to rejoin themselves to him.
Heart and passion rise to the surface in this letter. Not wanting to boast about himself, Paul indicates that the Corinthians themselves were his letter of recommendation. He appealed to their firsthand knowledge and experience. Paul also recounted the tribulations he endured to keep spreading the gospel.
