MKJV(i)
10 For the grief according to God works repentance to salvation, not to be regretted, but the grief of the world works out death.
11 For behold this same thing (you being grieved according to God); how much it worked out earnestness in you; but also defense; but also indignation; but also fear; but also desire; but also zeal; but also vengeance! In everything you approved yourselves to be clear in the matter.
12 Then, though I wrote to you, it was not on account of the one who did wrong, nor on account of the one who suffered wrong, but for the sake of revealing our earnestness on your behalf, for you before God.
