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. That may be why they tend to be loud in speech and outrageous in action, so that at least someone will notice them.
Negative attention is better than none.
What a blessing you are to others when you care enough to listen. Paul seemed almost incomplete without his friend. He needed that steady, constant, loving support that only Titus seemed able to give him. Many of us, I' m afraid, waver in our support of friends. We see their shortcomings and failings, and something in us makes us all too ready to point them out.
