2 Corinthians 2

Paul counseled the Corinthians that a certain man among them who had done wrong had been punished enough and now needed love and comforting. This was in order that the man not be overpowered by grief and so that Satan could not use this incident against them.

When someone sins against us, it is right that they be punished. However, we need to be sure we don't take it too far. Whenever possible, we need to seek to reconcile the relationship. If we let our thirst for revenge take over, we leave ourselves open to attacks from the devil.
