In these verses the apostle endeavours to comfort the Corinthians, upon whom his admonitions had had such good effect. And in order thereto, 1. He tells them he had a good design in his former epistle, which might be thought severe, 2 Cor. 7:12. It was not chiefly for his cause that did the wrong, not only for his benefit, much less merely that he should be punished; nor was it merely for his cause that suffered wrong, namely, the injured father, and that he might have what satisfaction could be given him; but it was also to manifest his great and sincere concern and care for them, for the whole church, lest that should suffer by letting such a crime, and the scandal thereof, remain among them without due remark and resentment. 2. He acquaints them with the joy of Titus as well as of himself upon the account of their repentance and good behaviour. Titus was rejoiced, and his spirit refreshed, with their comfort, and this comforted and rejoiced the apostle also (2 Cor. 7:13); and, as Titus was comforted while he was with them, so when he remembered his reception among them, expressing their obedience to the apostolical directions, and their fear and trembling at the reproofs that were given them, the thoughts of these things inflamed and increased his affections to them, 2 Cor. 7:15. Note, Great comfort and joy follow upon godly sorrow. As sin occasions general grief, so repentance and reformation occasion general joy. Paul was glad, and Titus was glad, and the Corinthians were comforted, and the penitent ought to be comforted; and well may all this joy be on earth, when there is joy in heaven over one sinner that repenteth. 3. He concludes this whole matter with expressing the entire confidence he had in them: He was not ashamed of his boasting concerning them to Titus (2 Cor. 7:14); for he was not disappointed in his expectation concerning them, which he signified to Titus, and he could now with great joy declare what confidence he still had in them as to all things, that he did not doubt of their good behaviour for the time to come. Note, It is a great comfort and joy to a faithful minister to have to do with a people whom he can confide in, and who he has reason to hope will comply with every thing he proposes to them that is for the glory of God, the credit of the gospel, and their advantage.
