9 Now I am glad, not that you had sorrow, but that your sorrow was the cause of a change of heart; for yours was a holy sorrow so that you might undergo no loss by us in anything. 10 For the sorrow which God gives is the cause of salvation through a change of heart, in which there is no reason for grief: but the sorrow of the world is a cause of death. 11 For you see what care was produced in you by this very sorrow of yours before God, what clearing of yourselves, what wrath against sin, what fear, what desire, what serious purpose, what punishment. In everything you have made it clear that you are free from sin in this business.
Matthew Henry's Commentary on 2 Corinthians 7:9-11
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.
