“Blessed are the peacemakers, for they will be called children of God.”
Matthew 5:9 (NIV)
Isaiah said that there was no peace for the wicked. If you want peace, then you must first have peace with God and then you must extend that peace to others. Peace is not the absence of conflict but absence of a proper relationship. Are you at peace with God? Are you living at peace, to the best of your ability, with others?
