<p>7:10 <i>For Godly sorrow works repentance to salvation, it brings no regret; but the sorrow of the world works death</i>- Paul is trying to turn around their 'We were really upset you know by your letter, really sad you should write to us like that' as meaning they had sorrowed with Godly sorrow. But this was a desperate attempt to make things seem right.</p><p>&ldquo;Godly sorrow worketh repentance to salvation not to be repented of&rdquo; by God (2 Cor. 7:10 AV) could mean that if we repent / change our minds, then God will not repent of His plan for saving us. But more likely is Paul's fear that they will regret their repentance, repenting of a repentance, as it were. And he says that this cannot be the case as Godly sorrow and repentance leads to salvation, and going back on it would mean death. Clearly Paul fears the Corinthians are unstable.</p>
