Williams(i)
10 For the sorrow that comes in accordance with the will of God results in repentance that leads to salvation and leaves no regrets, but the sorrow the world produces results in death.
11 For see what this very sorrow, suffered in accordance with the will of God, has done for you! How earnest it has made you, how concerned to clear yourselves, how indignant, how alarmed, how much it made you long to see me, how loyal to me, how determined to punish the offender! At every point you have cleared yourselves in the matter.
12 So, although I did write to you, it was not for the offender's sake, nor for the offended party's sake, but in the sight of God for the sake of having your enthusiasm for me made perfectly clear to you. This is why I am so comforted.
