“If your brother sins, go and show him his fault when the two of you are alone. If he listens to you, you have regained your brother.”
Jesus shows how to deal with sin in the church. It is the direct approach. Love does not mean overlooking a brother’s errors. The goal is restoration and salvation.
Don’t talk about other people’s sins to third parties. This is gossip. We sin by doing it. Don’t be a coward. Don’t contribute to division. Love others enough to correct them.
