Paul is writing to the Corinthians who had sinned in great ways and feels bad that he had to write the letter, but was glad it was received in the right manner. Many times today when you confront sin in the church it seems to be met with you are being judgmental and a trouble maker. We should always confront sin with a goal of bringing the sinner back to a right relationship with God and others. Never should we look down on those people or gossip about them in the guise of praying for someone in sin. The goal Paul wanted was achieved, they did everything they could in God’s power to get right with Him and others they had offended. If we are in a church where we are considered a trouble maker for standing up for the truth, we probably ought to look for another one. We are called to confront sin (Matthew 18:15-17) in the church to keep it pure and so that God can use it and us to do His will. Ask God to help you be all that He wants you to be today and pray for those who seem to be struggling and help them if you can.
2 Corinthians 7:8-11 For even if I made you sorry with my letter, I do not regret it; though I did regret it. For I perceive that the same epistle made you sorry, though only for a while. 9 Now I rejoice, not that you were made sorry, but that your sorrow led to repentance. For you were made sorry in a godly manner, that you might suffer loss from us in nothing. 10 For godly sorrow produces repentance leading to salvation, not to be regretted; but the sorrow of the world produces death. 11 For observe this very thing, that you sorrowed in a godly manner: What diligence it produced in you, what clearing of yourselves, what indignation, what fear, what vehement desire, what zeal, what vindication! In all things you proved yourselves to be clear in this matter.
