And lest, when I come again, my God will humble me among you, and that I shall mourn over many who have sinned already, and have not repented of the uncleanness and fornication and licentiousness which they have committed.
All Commentaries on 2 Corinthians 12:21 Go To 2 Corinthians 12
Fulgentius of Ruspe
AD 533
Concerning those who though within the church persisted in their evil deeds, he spoke thus to the Corinthians with these words of comfort: “I fear that when I come again, my God may humiliate me before you, and I may have to mourn over many of those who sinned earlier and have not repented of the impurity, immorality and licentiousness they practiced.” The apostle would not be saddened or humiliated in mourning over them if he believed that the forgiveness of sins would be granted to sinners and the wicked who continue to exasperate the divine justice without conversion of heart. The forgiveness of sins has no effect except in the conversion of the heart. We refer to those who have been converted by divine aid through the exercise of their own freedom of choice and whose lives are genuinely changed for the better. These converts will still occasionally sin, either through ignorance or through the stubbornness of a will that is knowingly lured by evil. They do not, however, stop asking for the forgiveness of their sins. .
