Why did Paul write 2 Corinthians after being forced out of Ephesus?
2 Corinthians was written sometime after Paul was forced out of Ephesus by intense pagan opposition to the gospel from Diana's followers, whose statue oversaw the city. He then went to Troas, ancient Troy, began a congregation, and expected Titus while under constant satanic attack.
Les explains that the second letter, the one under study, was written sometime after Paul had been forced out of Ephesus because of the tremendous hatred for the gospel from the pagan followers of Diana, whose statue oversaw the whole city of Ephesus. After leaving Ephesus, Paul went north into the northwest corner of what is now Turkey to ancient Troas, which was Troy, and evidently began a little congregation there. He was supposed to have met Titus—Les briefly questions Titus or Timothy but concludes it was Titus—and the reference is chapter 2, verse 13. Les gives this background to show why this man was under such constant satanic attack. He notes this is nothing new: from Genesis 3:15, when God said the seed of the woman would bruise the serpent’s head, Satan knew a Redeemer was coming and kicked into gear everything to prohibit the coming of a Redeemer for the human race.
