But God, who encourages those who are discouraged, encouraged us by the arrival of Titus. (2 Corinthians 7:6 NLT)
When Paul needed a lift to his spirits God chose Titus to be his encourager and sent him at exactly the right moment. Sometimes the greatest thing we can do for someone is to just be with them when they need us. Obviously, a word spoken at the right time never hurt anyone, but the physical presence of a friend is invaluable. Having Titus "arrive" made all the difference for Paul.
