This Is My Savior
In these two verses the prophet of God is describing the glorious Person and work of the Messiah, the Redeemer, our Savior, the Lord Jesus Christ, by whom God would fulfil all his promises of mercy and grace.
Here is THE INCARNATION AND VIRGIN BIRTH OF OUR LORD JESUS CHRIST - "For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder." Isaiah speaks first of the humanity of Christ. "For unto us a child is born." As the Son of man, Christ was born, the woman's Seed. In his humiliation, as a human baby, our Savior was as helpless as any other baby! He required the sustenance of his mother's breasts, the care of her hands, and the warmth of the blankets she wrapped around him. He was a real man. But he is also the eternal God. Here is the deity of our Savior. "Unto us a son is given." The Son of God was not born of the virgin, but given through the virgin's womb. Though he assumed our nature as the child born, he never ceased to be God, the Son given. And the prophet also proclaimed the exaltation of Christ as the incarnate God-man. "The government shall be upon his shoulder." As the reward of his obedience to God as our Representative, Christ has been given the government of creation, providence and grace.
Here is THE AMAZING CHARACTER OF OUR SAVIOR - "And his name shall be called Wonderful, Counsellor, the mighty God, the everlasting Father, the Prince of Peace." Yes, Jesus Christ is wonderful in all that he is and does. He is our Counsellor to teach us wisdom. He is God, the mighty One, the Second Person of the Holy Trinity. He is the Father of his spiritual seed, the church, forever. And he is the Prince of Peace. He promised peace, purchased peace, and bestows peace.
Here is THE GLORIOUS EXALTATION OF CHRIST - "Of the increase of his government and peace there shall be no end, upon the throne of David and upon his kingdom, to order it, and to establish it with judgment and with justice from henceforth, even forever!" His kingdom is an ever increasing, peaceful, prudent, just, and eternal, spiritual kingdom.
Here is THE INFALLIBLE SECURITY OF GOD'S PURPOSE - "The zeal of the Lord of hosts will perform this." God's zeal for his own name and his own people will accomplish his purpose of grace.
