God does at times intend for me and all to be sorrowful (9-10). This is called Godly sorrow. Godly sorrow comes when I recognize and accept that I did something that I know was wrong or when I do not do something that I should have done.
Godly sorrow does not end in regret. Regret is a product of worldly sorrow. Worldly sorrow brings self-condemnation and self-pity. Worldly sorrow does not lead to changes. Worldly sorrow does not lead to amends. World sorrow leads to death (10).
With Godly sorrow when I recognize and accept that I was in error I turn to God and ask for forgiveness and grace. I decide and set my willfully to do the right thing. This is repentance (10). Repentance includes amends to those I have done wrong to or who suffered because of my indiscretion, error, and sin (11).
God then always forgives those who act accordingly. He always saves. God in mercy will help those who turn to him and away from the error of their ways. There will be consequences to wrong behavior and words. Yet God does make amends.
The Corinthian church had a serious problem. Paul strongly stated so in his first letter to them. When they read it they acted accord to Godly sorrow. This produces earnestness and eagerness to clear themselves. They were alarmed and ready to see justice done (11). They purified themselves from that which contaminated body and spirit out of reverence for God (1)
