Luke 1:68, 69 Blessed be the Lord God of Israel; He hath visited and redeemed his people, and hath raised up an horn of salvation for us in the house of his servant David.
Mary’s Magnificat was inspired by the Holy Spirit to praise God for the promises fulfilled in the miraculous birth of her son, and to declare to all the Promise of Salvation through Him. Mary could not know naturally who this child was and what He would do, except by the revelation of the Spirit. So God, through Mary, reveals the significance of this Virgin Birth.
This is what happened: the Lord God broke into and entered our stream of human history from the spiritual, eternal world. God became a human. What for? To save a people for himself: “He has visited and redeemed His people.” When God “visits” it can be to bring a good promise or to inspect for judgment. In this case the visit is to “redeem.”
God Himself has come in the human flesh of Jesus of Nazareth to buy His people back from the slavery, ownership, and control of Sin, Death and Satan. That’s the promise of this Virgin-Born Child: He Redeems! He brings us back to God, to Life, to the Family, and to the Kingdom where we belong.
Jesus is the “horn of salvation” from the dynasty of King David. He is the promised Messiah, who has come to rule the people of God forever. A “horn” in the Bible symbolizes both authority and power. Authority is the right to rule, as absolute monarch, and power is the military force to back up the authority. With Jesus, the Kingdom (authority) has come to save us from the evil reign of Sin and Death; and with Jesus, the Gospel (the power of God unto salvation) has been proclaimed to save us. And so it ends up that for us every day we are saved.
