Mark 10:20-22:
“Teacher,” the man replied, “I’ve obeyed all these commandments since I was young.” Looking at the man, Jesus felt genuine love for him. “There is still one thing you haven’t done,” he told him. “Go and sell all your possessions and give the money to the poor, and you will have treasure in heaven. Then come, follow me.” At this the man’s face fell, and he went away sad, for he had many possessions.
Matthew 18:15-17:
“If another believer sins against you, go privately and point out the offense. If the other person listens and confesses it, you have won that person back. But if you are unsuccessful, take one or two others with you and go back again, so that everything you say can be confirmed by two or three witnesses. If the person still refuses to listen, take your case to the church. Then if he or she won’t accept the church’s decision, treat that person as a pagan or a corrupt tax collector.
2 Corinthians 7:8-10:
I am not sorry that I sent that severe letter to you, though I was sorry at first, for I knew it was painful to you for a little while. Now I am glad I sent it, not because it hurt you, but because the pain caused you to repent and change your ways. It was the kind of sorrow God wants his people to have, so you were not harmed by us in any way. For the kind of sorrow God wants us to experience leads us away from sin and results in salvation. There’s no regret for that kind of sorrow. But worldly sorrow, which lacks repentance, results in spiritual death.
