For if I have boasted - The apostle had given Titus a very high character of this Church, and of their attachment to himself; and doubtless this was the case previously to the evil teacher getting among them, who had succeeded in changing their conduct, and changing in a great measure their character also; but now they return to themselves, resume their lost ground, so that the good character which the apostle gave them before, and which they had for a time forfeited, is now as applicable to them as ever. Therefore his boasting of them is still found a truth.
For if I have boasted anything to him - This seems to imply that Paul had spoken most favorably to Titus of the Corinthians before he went among them. He had probably expressed his belief that he would be kindly received; that they would be disposed to listen to him, and to comply with the directions of the apostle; perhaps he had spoken to him of what he anticipated would be their liberality in regard to the collection which he was about to make for the poor saints at Jerusalem.
I am not ashamed - It has all turned out to be true. He has found it as I said it would be. All my expectations are realized; and you have been as kind, and hospitable, and benevolent as I assured him you would be.
As we spake all things to you in truth - Everything which I said to you was said in truth. All my promises to you, and all my commands, and all my reasonable expectations expressed to you, were sincere. I practiced no disguise, and all that I have said thus far turned out to be true.
Even so our boasting - My boasting of your character, and of your disposition to do right, which I made before Titus has turned out to be true. It was as I said it would be. I did not commend you too highly to him, as I did not overstate the matter to you in my Epistle.
