2 Corinthians 2:9

And this is the very thing I wrote you, so that when I came, I would not have sorrow from those who ought to make me rejoice; having confidence in you all that my joy would be the joy of you all.

For out of much affliction and anguish of heart I wrote to you with many tears; not so that you would be made sorrowful, but that you might know the love which I have abundantly for you.

So although I wrote to you, it was not for the sake of the offender nor for the sake of the one offended, but that your earnestness on our behalf might be manifested to you in the sight of God.

And his affection abounds all the more toward you, as he remembers the obedience of you all, how you received him with fear and trembling.

and are ready to punish all disobedience, whenever your obedience is fulfilled.
