Dr. Pratt tells us that Paul had established this church in Corinth during his second missionary journey and the believers there were very important to him. The first letter to the Corinthians was written in response to reports Paul had received about the church and a letter he received from them. Its purpose was to correct problems, edify and chastise. Paul addresses both doctrinal and practical themes in this epistle. Between this letter and his second letter to the Corinthians, Paul had visited the church at Corinth, but the visit was not a good one. This second letter again was the result of reports that Paul received about the church. False apostles had begun to influence the church and even turn some people against Paul. Paul had to refute these false apostles, mend his relationship with the believers there, set them straight on certain doctrines, and ask that they contribute to the needs of their fellow believers in Jerusalem.
