Paul had written to the people at Corinth before. He had visited there twice. Before he wrote this letter, Paul had met his friend Titus again. Titus had just returned from a visit to Corinth. He told Paul good news about the Christians there. See 2 Corinthians 7:5-7. So Paul wrote this letter to say that he was happy to hear this good news. He says that he will visit Corinth again soon.
