For unto us a child is born, unto is a son is given, and the government will be on his shoulders. And he will be called Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace. Isaiah 9:6
Jesus is peace. You might experience peace in other things or people, but that kind of peace is momentary. Jesus brings lasting peace. True peace can never be separated from His presence. You can experience eternal peace when you allow Him, the Prince of Peace to guard your heart and mind.
