2CO 7:12

12 So, even though I wrote that [severe] letter to you, I did not [write it just] so that [you would punish] the man who had done what was wrong. Also, I [did not write it] for the benefit of the person whom [he] had wronged. Instead, [I wrote it] so that, when you [read the letter], God would enable you to realize how much you really do respect [my authority].
