2 Corinthians 7:12-15

12So even though I wrote to you, it was neither on account of the one who did the wrong nor on account of the injured party, but rather that before God you could see for yourselves how devoted to us you are. 13By all this we are encouraged. In addition to our own encouragement, we were especially delighted to see how happy Titus was, because his spirit has been refreshed by all of you. 14I had boasted to him about you, and you have not embarrassed me. But just as everything we said to you was true, so our boasting about you to Titus has proved to be true as well. 15And his affection for you is all the greater when he remembers that you were all obedient, receiving him with fear and trembling.
