What is this covenant God made? How is the coming of Christ related to it? And how are you related to it? Those are the questions I want to address in a series of three articles based on a sermon I gave on this passage: (1) God’s covenant of grace, (2) Christ and the covenant, and (3) you and the covenant.
Zechariah said that God raised up this Savior “to remember his holy covenant.” What is a covenant? A covenant is a bond between two parties that establishes a relationship between them and defines the nature and obligations of the relationship, binding them together. A covenant typically states the parties to the covenant and its basis, promises, conditions, obligations, sanctions, and seals.
Some examples of covenants between humans are those made between kings and their vassals, between friends (like David and Jonathan) or peoples (like the Israelites and the Gibeonites), and the marriage covenant between husband and wife (see Malachi 2:14 - “she is your companion and your wife by covenant”). When God makes a covenant with people, he establishes a mutual bond of fellowship with them, takes them under his special care, and promises them eternal life and blessing.
The first covenant that God made with man is commonly called the covenant of works. He did not need to do it, but he voluntarily drew near to man, making a covenant with him. This is recounted in Genesis 2. As the Shorter Catechism says, “When God had created man, he entered into a covenant of life with him, upon condition of perfect obedience; forbidding him to eat of the tree of the knowledge of good and evil, upon pain of death” (WSC 12). As the Larger Catechism further explains, the tree of life was a pledge of this covenant and its promise, and the tree of the knowledge of good and evil was a commandment given in addition to the moral law to demonstrate the condition of the covenant: personal, perfect, and perpetual obedience to God (WLC 20). But the covenant of works was soon broken by the sin of our first parents. Unless redeemed by God, all the heirs of Adam are condemned as treacherous covenant-breakers. Fellowship with God was lost.
As early as Genesis 3:15, God published another covenant, a covenant upon different terms. This second covenant was made with sinners in need of salvation. God declared that he would put enmity between his people and the serpent and would raise up the offspring of the woman to crush the serpent’s head. We call this covenant his covenant of grace. We might also call it his covenant of mercy, "the mercy that he promised to our fathers" (Luke 1:72), for God entered into it out of his tender mercy, beholding us in our misery.
The covenant of grace is the abiding covenant God continued to renew with his people from generation to generation and which Zechariah mentions in his hymn. In the covenant of grace, God promises salvation to sinners on the basis of the obedience and sacrifice of Christ. In it, God requires that we believe in Christ and repent, faith in Christ being the only means by which we have a share in Christ’s mediation. Salvation and the everlasting inheritance is obtained by Christ and shared with those who are united to him. In this covenant of grace, sinners are saved by God to be his people, that they might glorify and enjoy him forever.
Thus, it is the case that the coming of Christ had been spoken of by the holy prophets from of old (Luke 1:70). Faith in God’s provision of Christ has been the only way of salvation for every generation. This was the covenant that God established with Noah and his household, saving them from judgment. As much of humanity wandered back into apostasy, this covenant was established with Abraham and made more fully known in his household. And thus Zechariah goes on to explain God’s holy covenant in terms of its administration to Abraham.
Zechariah gives an excellent description of God’s holy covenant. He says that God’s holy covenant was “the oath that he swore to our father Abraham.” What did God swear to Abraham? God swore “to grant us that we, being delivered from the hand of our enemies, might serve him without fear, in holiness and righteousness before him all our days” (Luke 1:73-75). This is a summery of the covenant promises God gave to Abraham in Genesis 12, 15, 17, and 22. This is a reversal of man’s fall. Through sin, we fell into the hand of our enemies, oppressed by the devil through fear of death, living in impurity and unrighteousness, separated from God’s fellowship, all our days. But God swore an oath, establishing a covenant, to deliver a people from this misery unto himself, making reconciliation, forgiving their sins, renewing them unto righteousness, that they might glorify and enjoy him forever.
God continued to renew this covenant with Abraham's descendants, with Isaac (Gen. 26:2-5) and Jacob (Gen. 28:13-15). Most dramatically, God renewed this covenant with the children of Israel in the days of Moses.
In those days, according to his covenant promise to Abraham, God delivered Israel from the hand of their enemies (i.e. Pharaoh) so that they might serve the Lord without fear, in holiness and righteousness before him all their days (Exod. 4:22-23, 6:2-8, Deut. 7:7-11). They were brought out of Egypt to serve the Lord as his people. The Passover, Exodus, and coming to Sinai to worship God were expressions of the covenant and a type of what more was promised, their ultimate hope: salvation from sin unto God through Jesus Christ.
This covenant was formally renewed with the children of Israel at Mount Sinai (Ex. 20-24) and again in Moab (Deut. 29-30), and again in the promised land under Joshua, at the beginning and end of the conquest (Josh. 8:30-35, 24:1-28). The covenant was externally administered differently before Christ than it is now. Then, God called his people to faith in Christ through promises, sacrifices, circumcision, passover, and other symbols and ceremonies foretelling the Christ to come. This administration of the covenant is called the old covenant. The covenant of grace is now administered more simply and powerfully in light of the Christ who has come, through the ministry of the Word, baptism, and the Lord’s Supper. This administration is called the new covenant. The difference between the old and the new is in the externals, not the substance. It is the same bond, the same principles, the same way of salvation - not two parallel covenants, but the same covenant for two different eras.
After Israel had settled down in the promised land, God made it clear that a greater fulfillment of this covenant would be brought about through the king of Israel, specifically, through King David and his heirs (2 Sam. 7, Ps. 72, 89, Is. 9:1-7). It would be from the line of David that the promised one would arise who would deliver God's people from their enemies and lead them in righteousness and peace forever, bringing all the nations under his blessed reign. This continued to be the prophetic hope even after the monarchy fell and Israel was scattered and began to return.
And so, God’s holy covenant, which Zechariah refers to, is his covenant of grace, “the oath that he swore to our father Abraham, to grant us that we, being delivered from the hand of our enemies, might serve him without fear, in holiness and righteousness before him all our days” (Luke 1:73-75).
