“For to us a child is born, to us 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. Of the increase of his government and peace there will be no end. He will reign on David’s throne and over his kingdom, establishing and upholding it with justice and righteousness from that time on and forever. The zeal of the Lord Almighty will accomplish this.” (Isaiah 9:6–7, NIV84)
Today we celebrate not just the birth of a baby, but the Incarnation of God the Son. Eternally existent, co-equal with the Father, by whom, through whom, and for whom all things were made. In Him are all things held together. He sits on the throne of David already reigning, but not yet returning. All authority has been given to Him, and by Him there will be justice.
But all this is for tomorrow. Today we remember that He came. We remember that He fulfilled the promises of God to us. We remember that He was and is what we are not. We remember that in Him lies all for which we hope, and in Him rests eternity.
Almighty God, who hast given us thy only-begotten Son to take our nature upon him, and as at this time to be born of a pure virgin: Grant that we, being regenerate and made thy children by adoption and grace, may daily be renewed by thy Holy Spirit; through the same our Lord Jesus Christ, who liveth and reigneth with thee and the same Spirit ever, one God, world without end. Amen.
