If God has laid it on your heart to confront someone for what they've done wrong, remember, your responsibility is to correct them, not to destroy them. Sometimes our pain causes us to want to permanently damage people, when God's intention is always to correct the behavior. At times, correcting behavior may hurt the other person, but it should always have a positive end in mind. Love does not mean that you let people run all over you. It means that you set boundaries and hold people accountable when they step over those boundaries. Confront, but always let love be your motivation. God bless!
