INTRODUCTION
One of the great recoveries of the Reformation was the notion of covenant. The doctrine of the covenant steers a biblical “middle way” between sacerdotal mysticism on the one hand and subjective mysticism on the other. God’s covenant is His objective personal relationship with human beings in history, with attendant blessings and curses. And because God deals with us in this way, we also deal with one another broadly through covenants in our families and nations.
The Text: “The secret things belong unto the Lord our God: but those things which are revealed belong unto us and to our children forever, that we may do all the words of this law” (Dt. 29:29).
SUMMARY OF THE TEXT
The Bible teaches that there are inscrutable thoughts and ways of God far past our finding out, but His covenant Word to us is not one of those things. That Word is the entire Bible from Genesis to Revelation, and it has come down to us by particular promises to particular people in history, sealed with sovereign signs, culminating in Jesus Christ, the Word made flesh for us and for our salvation. This sure Word of the Covenant is for us and for our children forever that we might walk with God under His blessing.
COVENANT OVERVIEW
In the beginning, God made a covenant with Adam commonly called the Covenant of Creation (also Covenant of Works/Life) in which Adam, as the federal head of the human race (Rom. 5:12-19), was promised life for obedience and death for disobedience (Gen. 2:15-17). When Adam disobeyed and broke that first covenant (cf. Hos. 6:7), God in His mercy made a second covenant, called the Covenant of Grace, in which He promised that the seed of the woman would one day crush the head of the seed of the serpent (Gen. 3:15). God demonstrated that grace in the substitutionary blood and skins of beasts by which God clothed and covered the nakedness and shame of Adam and Eve (Gen. 3:21). This Covenant of Grace was renewed with Noah after the flood and signified by the rainbow (Gen. 9:9-13), with Abraham and signified by circumcision (Gen. 12, 15, 17), with Moses and signified by the law and the sacrifices (Ex. 19-24, Lev. 1-7), and later with David and signified by the kingdom and the temple (2 Sam. 7).
These older administrations can all be referred to as the “Old Covenant/Testament,” types and shadows pointing to the coming of Christ, and now fulfilled in Christ. We call this new administration of the Covenant of Grace the “New Covenant/Testament” in His death and resurrection, and His heavenly rule and ministry for us and for the whole world, and it is signified by baptism and the Lord’s Supper (1 Cor. 10-11, Heb. 8-10). So we usually speak of one overarching Covenant of Grace with two administrations (Old and New Covenant).
COVENANT PRINCIPLES
Woven into this broad storyline is a pattern of God’s dealings with people as corporate bodies, specifically as families and nations. The Bible calls marriage a “covenant” and children are the natural, organic fruit of that covenant, such that Joshua can speak on behalf of his household (Prov. 2:17, Mal. 2:14, Ps. 127-128, Josh. 24:15). Every husband is the covenant “head” of his wife just as Christ is the head of His bride, the Church (Eph. 5:23). We see this covenant structure still in force when the promises of the covenant are applied to Gentile kids in Ephesus (Eph. 6:1-2). This is also why Job can pray and offer sacrifices on behalf of his grown children (Job 1:5). Peter preaches the gospel promises for “you and your children” (Acts 2:39), and Paul tells the Philippian jailer that if he believes, he will be saved and his household (Acts 16:31).
On the political side, Abraham made a “covenant” with Abimelech (Gen. 21:27), Isaac did the same (Gen. 26:28), and Jacob made a covenant with Laban (Gen. 31:44). Later, Jonathan and David made a covenant (1 Sam. 20:16, 23:18), as did Ben-Hadad and King Ahab (1 Kgs. 20:34). While Israel was a uniquely “holy nation” prefiguring the church (1 Pet. 2:5-9), there was also a civil aspect of the covenant renewed by faithful kings, re-committing to be faithful as a nation to God, as did Ezra and Nehemiah (2 Chron. 23:16, 34:31, Ez. 10:3, Neh. 9:38). All of this implies that while there is one, overarching Covenant of Grace administered through the Church, God has also established the covenant entities of family and nation, which are bound together by particular oaths and constitutions, according to their assignments under Christ.
APPLICATIONS
You Are Not Your Own: One of the central temptations of the Devil has always been toward self-centered individualism. Follow your own heart, find yourself, look out for number 1 are all slogans of this false gospel. If you try to find your own life like that, you will most certainly lose it. But if you lose your life in Christ, you will surely find it. And you will find it in your various covenant assignments to your family, church, and nation. You are who God says you are (Ps. 100:3). This world is what God says it is: marriage, justice, truth, goodness, and beauty.
Objectivity of the Covenant: Everyone born from Adam is born objectively under the death-curse of his covenantal disobedience. Just as God objectively marked Abraham’s descendants with a sign of His intention to save, so He does the same thing with baptism in the New Covenant. What is outwardly signified must be inwardly embraced and affirmed, but no amount of denial can erase that mark of God. This is how we may speak of faithful covenant members and unfaithful covenant members. And all of this means that we can trust His word. Let God be true and every man a liar (Rom. 3:4). You can hold God to His personal Word.
Real Blessings & Curses: Sometimes, friendly critics might accuse us of finding “covenants” everywhere and pretty soon we will be talking about covenant peanut butter and jelly sandwiches (and why not?). But the real point is that there is no neutrality anywhere. Everything is either pleasing to God or not. This is God’s world. While it is true that for all those in Christ, the curse of death has been taken away (Gal. 3:13), there are still blessings and curses in the New Covenant (1 Cor. 10-11). But this is a matter of great comfort for all who believe: “let us not be weary in well doing: for in due season we shall reap, if we faint not” (Gal. 6:7-8).
