The book of Second Corinthians is the second of two letters that are included in the New Testament of the Bible that were written by Paul the apostle to the church in Corinth. Paul wrote this letter from Ephesus around a.d. 55. At the time, Corinth was a busy seaport in Greece as described previously for 1 Corinthians.
This letter is a follow up to a previous letter (possibly lost) in which Paul has been very severe with the church in Corinth following an apparently quite unpleasant visit there which Paul had viewed as being unsuccessful. Paul has since learned from Titus that things are improving in Corinth as a result of his visit and he expresses his joy in this letter. He speaks of plans for a subsequent visit, the Christian ministry, collections for the poor, and opposition within the church.
