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.
8. with a letter—Greek, "in the letter" namely, the first Epistle to the Corinthians.
I do not repent, though I did repent—Translate, "I do not regret it, though I did regret it." The Greek words for regret and repent are distinct. Paul was almost regretting, through parental tenderness, his having used rebukes calculated to grieve the Corinthians; but now that he has learned from Titus the salutary effect produced on them, he no longer regrets it.
for I perceive, &c.—This is explanatory of "I did repent" or "regret it," and is parenthetical ("for I perceive that that Epistle did make you sorry, though it was but for a season").
