Zacharias has one last covenant to feature in his song of praise.
It is the new covenant, the one that links the Old Testament to the New Testament. While the Davidic covenant emphasizes a universal salvation in which the world will become perfect and eternal according to God’s promises, the Abrahamic covenant stresses the national deliverance of Israel from enemies and establishing the nation as a blessing for other nations. The New Covenant is markedly different for its promise of personal salvation.
The new covenant emphasizes the forgiveness of sins, a personal repentance that leads to salvation. God will regenerate the believer’s heart so that the believer will be made holy. This is the new covenant which John the Baptist prepares and Jesus fulfills.
And you, child, will be called the prophet of the Most High; for you will go on before the Lord to prepare His ways; to give to His people the knowledge of salvation by the forgiveness of their sins, because of the tender mercy of our God, with which the Sunrise from on high will visit us, to shine upon those who sit in darkness and the shadow of death, to guide our feet into the way of peace. – Luke 1:76-79
Who will John the Baptist be?
The newborn John will be a great man according to the angel’s message and according to Old Testament prophecy. In Isaiah 40:3-5, Malachi 3:1, and Malachi 4:5-6, it mentions that there will be a prophet calling the people of Israel to repent from the wilderness. A messenger to clear the way before the Messiah. He will restore the people to their God and turn them back to God. As the forerunner to the Messiah, John the Baptist will call Israel to repent and turn back to God. Zacharias acknowledges that his son will have a great mission and he will prepare the way for the Messiah.
What is the message of John the Baptist?
The message of John the Baptist is to repent.
The people of Israel must acknowledge that they need to be saved from their sins and nothing they can do can save themselves. It is by God’s grace and mercy that they can gain salvation. The Mosaic Law, the 10 Commandments, only seeks to condemn Israel because they cannot meet God’s standard of perfection. Animal sacrifices were not enough to cover their sins permanently, it was only a temporary solution. Therefore, there needs to be a final and perfect sacrifice for humanity, and that sacrifice is the Messiah.
John the Baptist will preach the gospel message, the message of the new covenant.
Was the New Covenant referenced in the Old Testament?
The new covenant is not different from what is written in the Old Testament. It specifies a time when the law of God will be written on man’s hearts. God will forgive their sins. God’s saving grace will cover His people with righteousness. They will be God’s people.
- Jeremiah 31:31-37
- Ezekiel 36: 22-38
- Isaiah 59:15-21 , Isaiah 60-62
The Sunrise from on High is a reference to God and Jesus as described in Psalm 107:10-16, Isaiah 9, 1 John 1:5, and Revelation 22:16. The new covenant made to Israel is fulfilled by the coming of the Messiah. The Messiah comes to provide personal salvation by the forgiveness of sins. When the nation of Israel recognizes the Messiah and repents, then the nation will enjoy the blessings described in the Abrahamic Covenant. And when all things have come to pass, the eternal kingdom will come and the Davidic Covenant will be fulfilled.
Zacharias’ song of praise recognizes the big picture of God’s message for humanity. He realizes how God will save His people with the coming of the Messiah. His child, John, is the forerunner to the Messiah and by these two miraculous births, the whole of history will be changed.
