For unto us a child is born, unto us a son is given, and the government will be upon His shoulders. And He will be called Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace. — Isaiah 9:6
The prince of peace is a person, and the angels' song announced him rather than any political settlement. He is our peace, and he left us his own settled calm, not the world's fragile version. That peace passes understanding and guards the hearts of those who trust him, even amid constant anxiety.
