6 But he who encourages those that are [brought] low, [even] God, encouraged us by the coming of Titus; 7 and not by his coming only, but also through the encouragement with which he was encouraged as to you; relating to us your ardent desire, your mourning, your zeal for me; so that I the more rejoiced. 8 For if also I grieved you in the letter, I do not regret [it], if even I have regretted it; for I see that that letter, if even [it were] only for a time, grieved you. 9 Now I rejoice, not that ye have been grieved, but that ye have been grieved to repentance; for ye have been grieved according to God, that in nothing ye might be injured by us. 10 For grief according to God works repentance to salvation, never to be regretted; but the grief of the world works death. 11 For, behold, this same thing, your being grieved according to God, how much diligence it wrought in you, but [what] excusing [of yourselves], but [what] indignation, but [what] fear, but [what] ardent desire, but [what] zeal, but [what] vengeance: in every way ye have proved yourselves to be pure in the matter.

12 So then, if also I wrote to you, [it was] not for the sake of him that injured, nor for the sake of him that was injured, but for the sake of our diligent zeal for you being manifested to you before God. 13 For this reason we have been encouraged. And we the rather rejoiced in our encouragement more abundantly by reason of the joy of Titus, because his spirit has been refreshed by you all. 14 Because if I boasted to him anything about you, I have not been put to shame; but as we have spoken to you all things in truth, so also our boasting to Titus has been [the] truth; 15 and his affections are more abundantly towards you, calling to mind the obedience of you all, how with fear and trembling ye received him. 16 I rejoice that in everything I am confident as to you.

Commentary on 2 Corinthians 7:5-11

(Read 2 Corinthians 7:5-11)

There were fightings without, or continual contentions with, and opposition from Jews and Gentiles; and there were fears within, and great concern for such as had embraced the Christian faith. But God comforts those who are cast down. We should look above and beyond all means and instruments, to God, as the author of all the consolation and good we enjoy. Sorrow according to the will of God, tending to the glory of God, and wrought by the Spirit of God, renders the heart humble, contrite, submissive, disposed to mortify every sin, and to walk in newness of life. And this repentance is connected with saving faith in Christ, and an interest in his atonement. There is a great difference between this sorrow of a godly sort, and the sorrow of the world. The happy fruits of true repentance are mentioned. Where the heart is changed, the life and actions will be changed. It wrought indignation at sin, at themselves, at the tempter and his instruments. It wrought a fear of watchfulness, and a cautious fear of sin. It wrought desire to be reconciled with God. It wrought zeal for duty, and against sin. It wrought revenge against sin and their own folly, by endeavours to make satisfaction for injuries done thereby. Deep humility before God, hatred of all sin, with faith in Christ, a new heart and a new life, make repentance unto salvation. May the Lord bestow it on every one of us.

Commentary on 2 Corinthians 7:12-16

(Read 2 Corinthians 7:12-16)

The apostle was not disappointed concerning them, which he signified to Titus; and he could with joy declare the confidence he had in them for the time to come. Here see the duties of a pastor and of his flock; the latter must lighten the troubles of the pastoral office, by respect and obedience; the former make a due return by his care of them, and cherish the flock by testimonies of satisfaction, joy, and tenderness.
