For to this end also did I write, that I might know the proof of you, whether you be obedient in all things.
All Commentaries on 2 Corinthians 2:9 Go To 2 Corinthians 2
John Chrysostom
AD 407
Paul needs to see that the Corinthians are as obedient in restoring the sinner as they had been in punishing him. For the punishment might have proceeded in part from envy and malice, but if they now proceed to restore him in love, that will show that their obedience is pure. This is the test of true disciples: if they obey not only when ordered to do something but on their own as well.
