A Better Covenant

Hebrews 8

Read Hebrews 8 before proceeding. If you have time, read Jeremiah 31:31–34 first. Keep your Bible open throughout this session.

For I will be merciful toward their evil deeds, and their sins I will remember no longer.

Hebrews 8:12

The Point of It All

The writer of Hebrews, in the first verse of this chapter, tells us something we might easily miss. “Now the main point of what we are saying is this.” He is pausing to name the heart of his argument. Everything up to this moment in the letter (the Son greater than angels, the Son made lower than angels, the merciful high priest, the throne of grace, the warnings and the anchor, the priesthood of Melchizedek) has been leading here. And here is where the writer stops and says: this is the point.

The point is that we have a high priest who is seated at the right hand of the Majesty in heaven, serving in the true tabernacle set up by the Lord and not by man. Christ’s priesthood is not an earthly office, it is a heavenly one. His sanctuary is not a tent pitched in a wilderness, it is the throne room of God Himself. And the covenant He mediates is not the one given at Sinai, it is a better covenant, resting on better promises. This, the writer says, is what he has been arguing all along. This is the point.

Chapter 8 is short, but it is the hinge of the letter. What preceded it has been establishing who Christ is and what kind of priest He is. What follows it, the long argument of chapters 9 and 10, will develop in detail the sanctuary in which He serves and the once-for-all sacrifice He has offered. Chapter 8 stands between these as the declaration that holds them together. A better priest serving in a better sanctuary offers a better covenant on better promises. Everything the writer has built is in these thirteen verses, and everything he will build rests on them.

And in the middle of the chapter, the writer quotes a longer passage from the Old Testament than he has anywhere else. Not a verse, not two verses woven together with commentary, but a whole prophecy, Jeremiah 31:31–34, given to us in full. This is the longest direct Old Testament quotation in the New Testament. The writer is saying, in effect: read this carefully. The new covenant we are living under is not a new idea invented in the first century. It is the fulfillment of what Jeremiah saw six hundred years before Christ. The Old Testament itself prophesied that the Sinai covenant would give way to a new one. What we have, we have because it was promised.

The True Tabernacle

“Now the main point of what we are saying is this: We have such a high priest, one who sat down at the right hand of the throne of the Majesty in heaven, a minister in the sanctuary and the true tabernacle that the Lord, not man, set up.”

Two claims to hold together. The first is the location of Christ’s priestly service. He sat down at the right hand of the throne of the Majesty in heaven. We have met this image before: in 1:3, where the writer first introduced the enthroned Son, and repeatedly since. Christ is not serving in an earthly sanctuary. He is not pacing the courts of a temple. He is seated at God’s right hand, and from there He exercises His priesthood over the heavenly sanctuary.

The second is the nature of the sanctuary He serves in. It is “the true tabernacle that the Lord, not man, set up.” The writer is not dismissing the tabernacle of Moses; he will spend most of chapter 9 describing it carefully. What he is saying is that the tabernacle Moses built was a copy of something greater. The true tabernacle, the real sanctuary, the one that God Himself set up and that cannot be shaken, is the heavenly one. The earthly one was a teaching tool, a pattern, a sign pointing to the reality. And now the reality has come, and our priest serves in it.

This is a way of thinking about the Old Testament that takes the Old Testament seriously. The writer does not dismiss the tabernacle, the sacrifices, the Levitical system, the Day of Atonement. He honors them as what they were: real and genuine worship, given by God, pointing forward to what they could not accomplish themselves. The shadow is real, but it is only a shadow. The substance is what casts the shadow. And the substance, the writer says, is in heaven, where Christ is serving. Whatever we thought worship on earth accomplished in the old covenant, what Christ is now doing in the heavenly sanctuary accomplishes more. Because what Christ is doing is the thing the earthly worship was pointing to all along.

“For every high priest is appointed to offer both gifts and sacrifices. So this one too had to have something to offer.” A priest, by definition, offers. That is what priests do. The Levitical priest offered the daily sacrifices at the altar in the court of the tabernacle; the high priest, on the Day of Atonement, offered the blood of the sacrifice within the Most Holy Place. Christ too has something to offer. What and how, the writer has not yet fully explained; the next chapters will take that up. But here he notes simply that Christ’s priesthood, like every priesthood, involves an offering. The offering is not yet described, only its necessity.

“Now if he were on earth, he would not be a priest, since there are already priests who offer the gifts prescribed by the law. The place where they serve is a sketch and shadow of the heavenly sanctuary.” A striking sentence. If Christ were serving on earth, the writer says, He would not be a priest, because the earthly priesthood is filled, and the Law regulates who can hold it. From the tribe of Judah, as Christ is, no one could be an earthly priest. But Christ is not on earth. He is in heaven. And in heaven, He serves in the true tabernacle, the reality of which the earthly priests, for all their legitimate service, had only the sketch and shadow.

Moses was instructed, when he built the tabernacle, to make everything “according to the design shown to you on the mountain.” The earthly tabernacle was built to specifications. It was not an arbitrary structure. It was a deliberate model of something Moses had actually been shown: the heavenly reality, the pattern in the mind of God. The tabernacle was a kind of scale replica, made on earth, of a sanctuary that already existed in heaven. When we understand this, we understand what the writer has been doing. He is not comparing Christ to Levitical priests as though they served equivalent sanctuaries and Christ’s was merely nicer. He is saying that the Levitical priests served the model, while Christ serves the original. The shadow worshipers worked faithfully; they just worked with shadow.

A Superior Ministry

“But now Jesus has obtained a superior ministry, since the covenant that he mediates is also better and is enacted on better promises.”

Three comparatives in one verse: a superior ministry, a better covenant, better promises. This is the key claim of the chapter, and the reason the writer has been arguing for a new priesthood at all. If all Christ were doing was running the same program under new management, the argument would not be worth making. But the ministry is superior. The covenant is better. The promises on which the covenant rests are better. These are not small distinctions; they are the difference between a system that could only point toward salvation and a system that actually delivers it.

What is a covenant, in the biblical sense? It is a formal relationship between God and His people, with stated terms, given promises, and established obligations. The Old Testament is a story of covenants: with Noah, with Abraham, with David, and most comprehensively with Israel through Moses at Sinai. The covenant at Sinai is the one most in view when Hebrews talks about the “old” covenant or the “first” covenant. It was the covenant that included the Law, the tabernacle, the priesthood, the sacrifices. And it was a real covenant, with real promises, under real terms.

But it had a weakness, and the writer is about to name it. “For if that first covenant had been faultless, no one would have looked for a second one.” The old covenant was not faultless. This does not mean it was poorly designed or that God made a mistake. The fault the writer has in view is not a flaw in God’s giving but a limitation in what the covenant, by its nature, could accomplish. It could prescribe righteousness; it could not produce it. It could require obedience; it could not enable it. It could expose sin through the sacrificial system; it could not finally remove sin. The fault was that the covenant placed the weight on the people, and the people could not bear the weight.

“But showing its fault, God says to them…” Before the writer gives us the prophetic text, notice where the prophecy itself locates the breakdown. The Greek of this line can be read as God finding fault with the covenant or with the people, and translations differ. But Jeremiah leaves no doubt: “they did not continue in my covenant.” The covenant was not broken because the Law was bad or because God’s standards were too high. It was broken because the people did not keep it. Israel repeatedly, through the centuries, failed to keep covenant. The prophets told them so. The exile demonstrated it. The Law was good; the people were not able, on their own, to do what the Law required. A new covenant would be necessary not because the old one was defective but because the people under it were.

The Days Are Coming

The writer now quotes Jeremiah 31:31–34, the longest Old Testament quotation in the New Testament. The prophecy is so central to his argument that he gives it to us in full. Read it slowly.

“Look, the days are coming, says the Lord, when I will complete a new covenant with the house of Israel and with the house of Judah. It will not be like the covenant that I made with their fathers, on the day when I took them by the hand to lead them out of Egypt, because they did not continue in my covenant and I had no regard for them, says the Lord. For this is the covenant that I will establish with the house of Israel after those days, says the Lord. I will put my laws in their minds and I will inscribe them on their hearts. And I will be their God and they will be my people. And there will be no need at all for each one to teach his countryman or each one to teach his brother saying, ‘Know the Lord,’ since they will all know me, from the least to the greatest. For I will be merciful toward their evil deeds, and their sins I will remember no longer.”

Six hundred years before Christ, in a time of national collapse, the prophet Jeremiah saw a new covenant coming. Israel had failed the old one. The northern kingdom was gone. Judah was about to be taken into Babylonian exile. The temple would be destroyed. The land promised to Abraham would be lost, at least for a season. And in the middle of all that failure, God, through Jeremiah, announced that a new covenant was coming. Not a revision of the old one. Not a repaired version. A new one. With three promises that define it.

The first promise: “I will put my laws in their minds and I will inscribe them on their hearts.” The Law, under the old covenant, was written on stone tablets: external, given from the outside, requiring study and memorization and effort to be kept in mind. The Law, under the new covenant, would be written on hearts and minds: internal, so integrated into the regenerate person that obeying God would not be the pursuit of an external code but the expression of a renewed nature. This does not mean Christians never need to learn God’s Law or read God’s Word; of course we do. It means that the Holy Spirit, working through that Word, produces in the heart of the believer a new disposition toward God’s will, so that what was formerly a burden becomes, in some measure, a delight. Where the old covenant produced external conformity in its best moments, the new covenant produces transformed people.

The second promise: “they will all know me, from the least to the greatest.” Under the old covenant, knowledge of God was concentrated in a priestly and prophetic class. The priests taught the Law; the prophets delivered the Word; the people heard, often at a distance, through intermediaries. Under the new covenant, this changes. Every believer, from the humblest to the most eminent, knows God personally. Not through an unmediated inner voice, but through the Gospel, Baptism, Absolution, and the Supper, through which the Holy Spirit gives and sustains faith (Augsburg Confession V). Here is the root of what the Reformation called the priesthood of all believers: every baptized Christian comes to the Father through Christ alone and may approach the throne of grace with confidence. That does not make the pastoral office unnecessary. God has given pastors and calls them to preach publicly and administer the Sacraments (Augsburg Confession XIV). But pastors do not stand as mediators between Christ and Christians; they publicly deliver the means by which Christ Himself comes to His people. You do not reach God by going through your pastor. Through your pastor’s mouth and hands, God comes to you in the Word, the Absolution, and the Supper, as He first came to you in Baptism.

The third promise, and the one the writer chooses to quote last and leave hanging: “For I will be merciful toward their evil deeds, and their sins I will remember no longer.” This is the heart of the new covenant. Mercy toward evil deeds. Forgetting of sins. Under the old covenant, sins were not forgotten; they were covered, temporarily, by the annual sacrifice of the Day of Atonement, only to need covering again the next year. The sins were remembered, the writer will say in the next chapter, year after year. Under the new covenant, God remembers them no longer. They are not merely covered; they are forgotten. This is the forgiveness Christ’s priesthood delivers.

Their Sins I Will Remember No Longer

Let us stay here for a moment, because this is one of the richest promises in the whole of Scripture, and many Christians do not let it land the way it should.

God, the writer says, does not merely forgive our sins. God forgets them. Now, this is not a claim about divine memory in some philosophical sense; God, of course, knows all things. But the language of remembering and forgetting in Scripture is covenant language. To “remember” a sin, in this idiom, is to hold it against the sinner, to keep it on the books, to let it stand between you and the one who committed it. To “forget” a sin is to set it aside, to treat it as not counting, to refuse to let it define the relationship anymore. God, under the new covenant, forgets our sins in this sense. He does not hold them against us. He does not keep a running account. He does not bring them back up in times of displeasure. They are, in the covenant sense, gone.

This is the gospel at its most gracious, and it has pastoral implications many believers never fully grasp. If God has forgotten your sins, why do you keep rehearsing them before Him? Why do you keep bringing them up as evidence against yourself? Why do you treat them as permanent features of your identity before God? He does not. When you come to the throne of grace, you do not come with a long list of past sins that you must re-confess and re-work through before God can meet you. You come to a God who does not have that list anymore. He has thrown it away. He will not remember it. The sins are, for Him, forgotten. And if He has forgotten them, your ongoing rehearsal of them is not humility; it is a refusal to take the covenant at its word.

The Lutheran tradition has always understood this with particular clarity. Luther, wrestling with his own conscience, came to see that the gospel was not merely a general promise that God might forgive those who tried hard enough, but a specific, absolute promise that God has actually forgiven, in Christ, those who are joined to Christ. The certainty of forgiveness is the heart of the Christian life. Without it, the Christian is always looking over her shoulder, always measuring, always afraid that some sin will come back up and disqualify her. With it, she can live free (not free to sin, but free from the tyranny of past sin) because she knows, with the certainty of God’s covenant word, that her sins have been forgotten.

When you receive absolution, whether from a pastor in private confession or in the corporate confession and absolution of the liturgy, and when you receive the Supper, where Christ gives His body and blood for the forgiveness of sins, you are hearing the voice of the new covenant. Your sins are forgiven. God will remember them no longer. This is not hope; it is fact. And it is the fact on which the whole Christian life of peace rests.

What Is Growing Obsolete and Aging

The writer closes the chapter with one short sentence that has occupied theologians and pastors ever since. “When he speaks of a new covenant, he makes the first obsolete. Now what is growing obsolete and aging is about to disappear.”

Read the sentence carefully. The writer does not say the old covenant was evil, or that the Law was bad, or that the whole apparatus of the old covenant should be dismissed. Nor was the old covenant mere legalism: it carried real promise and real grace, the fault lay with the people and not with God’s gift (8:8–9), and Abraham, David, and faithful Israel were saved as we are, by faith in the promised Christ. What the writer says is that the old covenant is obsolete: superseded, no longer the operative framework, replaced by what it was pointing to. And he says it is “growing obsolete” and “aging,” which is striking language. If, as many scholars think, Hebrews was written before AD 70, the temple in Jerusalem still stood. The sacrificial system was still operating. Jewish priests were still offering daily sacrifices. The old covenant, outwardly, was still fully functional. But the writer says it is already “growing obsolete”: the new covenant, inaugurated in Christ, has already rendered the old one spiritually inoperative, even while its outward forms continued.

In AD 70 the Roman armies destroyed the temple, quite possibly within a few years of the letter’s writing. The sacrificial system ended. The priestly lineage was scattered. What the writer called “about to disappear” disappeared in fact. The writer did not need a timeline to say so. He understood that what Christ had accomplished had already made the old system theologically obsolete. The temple’s destruction was the outward confirmation of a covenantal change that had already occurred at the cross.

This has implications for how Christians read the Old Testament. We do not read it as though we are still trying to keep the ceremonial law. We do not sacrifice animals. We do not observe the priestly purity codes. We do not approach God through a mediating priesthood of earthly men. All of that has been fulfilled in Christ and rendered obsolete. (God’s moral will, summarized in the Ten Commandments, is another matter: it still shows us our sin and still guides the new life, as the Formula of Concord teaches in Article VI.) What the Old Testament does for us is something different. It shows us how the one God who dealt with His people then is the same God who deals with us now. It teaches us about His holiness, His mercy, His faithfulness, and the pattern of His saving work. It gives us prophecies that Christ fulfilled, types that Christ fulfilled, and promises that are now ours through Him. The Old Testament is not discarded. It is read in its proper place: as the preparation for the new covenant we are now living under.

Gathering the Threads

A short chapter, but a pivotal one. Four movements, and they belong together.

The first is the true tabernacle. Christ is seated at the right hand of the Majesty in heaven, serving in the sanctuary that God Himself set up, not in a sanctuary made by human hands. The earthly tabernacle was a sketch and shadow of the heavenly reality. Christ serves in the reality.

The second is the superior ministry. Christ’s ministry is superior to the Levitical ministry because the covenant He mediates is better than the old covenant. The old covenant was not faultless, not because it was wrongly designed, but because the people under it could not keep it. A new covenant was necessary.

The third is Jeremiah 31. The new covenant was prophesied six hundred years before Christ. Its three promises shape the Christian life: the Law written on hearts, the knowledge of God given to all His people, and the forgetting of sins. This is the covenant we are living under.

The fourth is the obsolescence of the old. By announcing a new covenant, God declared the old obsolete. What had been outwardly continuing when Hebrews was written would soon disappear in fact, a historical confirmation of the theological reality that Christ had already made.

The pastoral weight of this chapter is enormous, and it centers on that last promise of Jeremiah: God will remember our sins no longer. This is not a hope, not a possibility, not a reward for performance. It is a covenant promise, given by God, secured by Christ’s priestly work, and delivered to us in the means of grace. Receive it. Let your sins be forgotten, as God has forgotten them. Let the rehearsal of old failures stop. Come to the throne of grace as one whose sins are not on file. That is who you are, under the covenant Christ mediates. That is who you have been since Baptism. That is who you will be forever.

And as we close: notice how this chapter has brought together everything the letter has been teaching. The enthroned Son from chapter 1. The throne of grace from chapter 4. The forerunner and anchor from chapter 6. The permanent priest from chapter 7. All converge here, in the declaration that we have a superior ministry, a better covenant, and better promises. Hebrews has not been writing a series of disconnected chapters. It has been building one sustained argument, and chapter 8 is where the argument comes to its climactic statement. What remains in chapters 9 and 10 will fill in the details of the sanctuary and the sacrifice. But the point, as the writer himself says, has now been named.

For Discussion

1. The writer calls verse 1 of this chapter “the main point of what we are saying.” Why is this moment in the letter a good place to pause and declare the main point? What has the letter been building toward that becomes visible here?
2. The earthly sanctuary was a “sketch and shadow” of the heavenly reality. What does it change about the way we read the Old Testament to know that its worship structures were deliberate models pointing toward what Christ would accomplish?
3. Jeremiah prophesied the new covenant six hundred years before Christ. Why does it matter, for our confidence in the new covenant, that it was promised so long before it came? What does this tell us about God’s faithfulness across centuries?
4. The first promise of the new covenant is that the Law will be written on our hearts and minds. Through what means does the Holy Spirit do this inward work? Where have you seen its fruit in your own Christian life? Where do you still feel the external nature of God’s commands more than the internal delight of them?
5. “Their sins I will remember no longer.” Why do Christians so often struggle to let go of sins that God has promised to forget? What difference does it make, in daily Christian life, to take this promise as actually true, to live as though your past sins are forgotten by God?
6. The writer says the old covenant is “growing obsolete.” What does it mean for Christians today that the old covenant is obsolete? What remains permanently true from the Old Testament, and what has been superseded? How do we read the Old Testament rightly as Christians?

Looking Ahead

Session 9 takes up Hebrews 9, where the writer develops in detail the earthly sanctuary, its rituals, and the heavenly sanctuary in which Christ has accomplished what the earthly one could only shadow. The chapter moves from the description of the tabernacle to the inadequacy of its sacrifices to the glorious declaration that Christ, by His own blood, entered once for all into the most holy place, securing eternal redemption.

Before next session, read Hebrews 9 carefully, and consider glancing at Exodus 25–26 or Leviticus 16 if you want background on the tabernacle and the Day of Atonement. The writer expects a certain familiarity with these, and even a brief refresher will make chapter 9 land more powerfully.

Closing Prayer

Father of mercies, who promised through the prophet Jeremiah a new covenant written on our hearts, in which You would remember our sins no longer: we thank You that the promise has come true in Your Son. Write Your law on our hearts, Lord. Make us Your people and be our God. And when we are tempted to rehearse sins You have already forgotten, remind us that the covenant is secure, that the priest is seated, that the sanctuary is heavenly, and that the mercy is real. In the name of Jesus Christ, mediator of the better covenant. Amen.
