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, Co2 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 (Co2 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, Co2 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 (Co2 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.

And his inward affection - Τα σπλαγχνα αυτου· Those bowels of his - his most tender affection. For the meaning of this word see the note on Mat 9:36.
Whilst he remembereth the obedience of you all - This is a very natural picture; he represents Titus as overjoyed even while he is delivering his account of the Corinthian Church. He expatiated on it with extreme delight, and thereby showed at once both his love for St. Paul and his love for them. He loved them because they so loved the apostle; and he loved them because they had shown such kindness to himself; and he loved them because he found so many excellent and rare gifts, joined to so much humility, producing such an exemplary and holy life.
With fear and trembling ye received him - Ye reverenced his authority; ye were obedient to his directions; and ye dreaded lest any thing should be undone or ill done which he had delivered to you in the name of God.

And his inward affection is more abundant toward you,.... Or "his bowels"; denoting the tenderness of his heart, the strength of his affections, which inwardly and to a very great degree moved towards them; especially

whilst he remembereth the obedience of you all; to him, and to me by him; to the advice and orders given, which were so readily, cheerfully, and universally complied with; and

how with fear and trembling you received him; that is, with great humility and respect, with much deference to him: considering his character as a minister of the Gospel, and as one sent by the apostle to them, they embraced him with great marks of honour and esteem; for this is not to be understood of any inward slavish fear or dread of mind, or trembling of body at the sight of him, and because he came to know their estate, and with reproofs from the apostle to them.

his inward affection--literally, "bowels" (compare Co2 6:12; Phi 1:8; Phi 2:1; Col 3:12).

obedience-- (Co2 2:9).

fear and trembling--with trembling anxiety to obey my wishes, and fearful lest there should be aught in yourselves to offend him and me (Co2 7:11; compare Co1 2:3).
