Paul eventually met Titus in Macedonia and was overjoyed to learn that everything was patched up in Corinth, and whatever misunderstanding had arisen was now gone. Now the Bible doesn't tell us how Titus calmed the stormy waters in the Corinthian Church, but we know he did. He had that gift of promoting communication. Nearly everything we worry about is made worse by poor communication. Parents are often at odds with their children because they don't understand how their children perceive them.
Children are often angry with their parents for being so old-fashioned.
Nations are often hostile to other nations because the barriers of language and custom bury the common concerns all people share. I suspect that one reason Titus was successful as a peacemaker is that he was a good listener. He must have listened to the Corinthians, waiting patiently while they poured out their frustration and hurt, and only then spoke quietly and persuasively the truth. Titus too, must have had the gift of being a loving listener. Most angry people have no one who will listen to them.
