But I pray to God that you may do nothing wrong. Not so that we [and our teaching] may appear to be approved, but that you may continue doing what is right, even though we [by comparison] may seem to have failed.

Now whomever you forgive [for doing] anything [wrong], I will forgive also. For indeed, whatever I have forgiven, if I have [actually] forgiven anything, has been for your sakes in the sight of Christ. [Note: Paul seems to be saying "Since my forgiveness depends on your forgiveness of the man, I am not sure of my forgiveness because I am not sure of yours"].

See how the very fact that you were made sorry from a godly motive has produced earnestness in you! [It produced] a desire to vindicate yourselves [i.e., by making amends for your wrongdoing]; an attitude of just anger [i.e., toward the wrongdoers]; a sense of fear [i.e., a fear of God for doing wrong]; an eager desire [i.e., to do the right thing]; a zeal [i.e., to correct problems]; and an attitude of avenging [i.e., that punished the wrongdoer]. You demonstrated in everything [you did] that you were pure [i.e., innocent] in this matter. [Note: This whole description of their conduct appears to be a reference to the incident mentioned in 2:1-11].
