Chapter 10: The New Covenant

The new covenant is not confined to Jeremiah 31 and its quotation in Hebrews 8. It is woven throughout Scripture. Moses anticipates it in Leviticus and Deuteronomy; Isaiah, Jeremiah, Micah, and Ezekiel proclaim it in connection with Israel’s restoration; Jesus inaugurates it at the Last Supper; Paul describes himself as its minister; and Hebrews explains its priestly, sacrificial, and heavenly dimensions. The new covenant therefore brings the entire biblical story into focus. It fulfills the promises made to Abraham, replaces the broken Mosaic covenant, and establishes through Christ the final and everlasting form of the Covenant of Grace.

Six Key Affirmations about the New Covenant

Michael Brown and Zach Keele in their book Sacred Bond (Reformed Fellowship, 2019) provide a wonderful summary of the new covenant with six basic affirmations.

First, the new covenant is new in relation to the Mosaic covenant, not in relation to the Abrahamic covenant. The Abrahamic covenant is a promise covenant and a formal administration of the Covenant of Grace. The new covenant fulfills those Abrahamic promises. By contrast, the Mosaic covenant, considered narrowly as the national law covenant, was breakable and temporary. It is this Mosaic covenant that Scripture identifies as the “old covenant.”

Second, the new covenant is mediated by Christ rather than Moses. Moses was a faithful servant in God’s house and a type of the mediator to come, but Christ is the Son over God’s house.

“Moses was faithful in all God’s house as a servant … but Christ is faithful over God’s house as a son.” —Hebrews 3:5–6

Third, the new covenant blesses rather than curses. Paul calls the old covenant a ministry of death and condemnation because its law exposed sin and pronounced the covenant curse. The new covenant is a ministry of the Spirit, life, righteousness, and justification.

Fourth, the new covenant provides internal renewal by the Holy Spirit. Jeremiah speaks of the law written on the heart, while Ezekiel explicitly identifies the Spirit as the agent of this transformation.

“I will sprinkle clean water on you, and you shall be clean from all your uncleannesses … And I will give you a new heart, and a new spirit I will put within you … And I will put my Spirit within you, and cause you to walk in my statutes.” —Ezekiel 36:25–27

Fifth, the new covenant includes believing Jews and Gentiles. It fulfills the promise to Abraham that all the nations would be blessed through him. Membership in the eschatological people of God is therefore defined by union with Christ and faith in him rather than by ethnic descent.

Sixth, the new covenant is permanent. Whereas the Mosaic covenant was temporary and designed to be replaced, the new covenant is final and irreplaceable. Scripture therefore also calls it the “everlasting covenant” (Isa. 55:3; 61:8; Jer. 32:40; 50:5; Ezek. 16:60; 37:26; Heb. 13:20). No later covenant will supersede it, because Christ has already accomplished the final redemption and established the final covenant.

The Abrahamic, Mosaic, and New Covenants

The biblical-theological structure of the new covenant can be understood through the relationship among three covenants: Abrahamic, Mosaic, and new. The Abrahamic covenant contains the gracious promise. The Mosaic covenant introduces the law covenant governing Israel’s national life in the land. Israel breaks that covenant and suffers its curses in exile. The new covenant then fulfills the Abrahamic promise beyond the ruins of the Mosaic order.

This relationship is already visible within the Mosaic law itself. The covenant curses of Leviticus 26 and Deuteronomy 27–30 predict Israel’s apostasy, defeat, devastation, and exile. Yet those same passages also look beyond judgment to restoration on the basis of God’s covenant with Abraham. The Mosaic covenant therefore anticipates both its own failure and the coming of a more effective covenant.

The Blessings and Curses of Leviticus 26

Leviticus 26 begins with the blessing promised for covenant obedience. Israel will enjoy rain, fruitfulness, peace, victory, and God’s dwelling presence in the land.

“If you walk in my statutes and observe my commandments and do them, then I will give you your rains in their season … I will make my dwelling among you … And I will walk among you and will be your God, and you shall be my people.” —Leviticus 26:3–4, 11–12

The curse section is much longer and increasingly severe. Israel will experience disease, military defeat, famine, devastation, the destruction of its sanctuaries, and finally exile among the nations. Moses is not merely describing a hypothetical possibility. His language becomes prophetic, anticipating the actual course of Israel’s history and the Babylonian exile.

“I will bring a sword upon you, that shall execute vengeance for the covenant … I will lay your cities waste and will make your sanctuaries desolate … And I will scatter you among the nations.” —Leviticus 26:25, 31, 33

Yet judgment is not the final word. When Israel is humbled, God promises to remember the covenant with Abraham, Isaac, and Jacob.

“Then I will remember my covenant with Jacob, and I will remember my covenant with Isaac and my covenant with Abraham, and I will remember the land.” —Leviticus 26:42

The restoration following the Mosaic curse therefore rests not on a renewal of the Mosaic works principle but on the gracious and unbreakable Abrahamic promise.

Deuteronomy 30 and the Circumcision of the Heart

Deuteronomy 30 makes the same movement from curse and exile to restoration and inward renewal. Moses assumes that the blessings and curses will come upon Israel and that the people will be scattered among the nations. He then looks beyond exile to a divine act of regathering.

“The LORD your God will restore your fortunes and have mercy on you, and he will gather you again from all the peoples where the LORD your God has scattered you.” —Deuteronomy 30:3

The decisive new-covenant promise appears in verse 6:

“The LORD your God will circumcise your heart and the heart of your offspring, so that you will love the LORD your God with all your heart and with all your soul, that you may live.” —Deuteronomy 30:6

Israel lost the land because its heart was uncircumcised and it failed to love and obey God. Permanent restoration therefore requires more than another opportunity to obey. God himself must change the heart. The promise of a circumcised heart in Deuteronomy 30 anticipates Jeremiah’s promise that God will write the law on the heart and Ezekiel’s promise of the indwelling Spirit.

The Abrahamic, Mosaic, and new covenants thus form a covenantal triangle. God remembers Abraham, judges Israel under Moses, and restores his people through the inwardly effective new covenant.

The Exile and the Prophets

The great preaching prophets stand at the intersection between the old and new covenants. They look backward upon the ruins of the Mosaic order and forward to the glory of the coming covenant in Christ. They describe Israel’s restoration after exile, but this restoration is the second-level fulfillment of the Abrahamic covenant, not merely the reestablishment of the old national kingdom.

The prophets often use the language of the first-level fulfillment—Israel, land, Jerusalem, David, temple, fruitfulness, and national restoration—to describe the greater fulfillment in Christ. Their imagery is earthly and typological, but its ultimate referent is eschatological: Christ, the church, the heavenly inheritance, the new creation, and God’s final dwelling with his people.

The New Covenant in Micah

Micah connects the forgiveness of Israel’s sins directly to God’s oath to Abraham.

“Who is a God like you, pardoning iniquity and passing over transgression for the remnant of his inheritance? … You will show faithfulness to Jacob and steadfast love to Abraham, as you have sworn to our fathers from the days of old.” —Micah 7:18, 20

The new covenant is therefore not a departure from the Abrahamic covenant. It is the climactic display of God’s faithfulness to the oath he swore to the fathers.

The New Covenant in Isaiah

The Suffering Servant and the Abrahamic Offspring

Isaiah 53 describes the suffering servant’s atoning work in Abrahamic terms. The servant offers himself for guilt, bears iniquities, makes many righteous, and receives the many and the mighty as his inheritance.

“When his soul makes an offering for guilt, he shall see his offspring … By his knowledge shall the righteous one, my servant, make many to be accounted righteous, and he shall bear their iniquities.” —Isaiah 53:10–11

The servant receives an offspring through his sacrificial death. He fulfills the promise that Abraham would become a great and mighty nation, not by producing an earthly nation according to the flesh, but by justifying the many for whom he bears sin.

The Barren Woman and the Inclusion of the Nations

Isaiah 54 follows immediately from the servant’s victory. Barren Zion is commanded to sing because her children will become more numerous than she imagined.

“Sing, O barren one, who did not bear … For the children of the desolate one will be more than the children of her who is married.” —Isaiah 54:1

The tent must be enlarged because the restored people of God will spread outward among the nations.

“Enlarge the place of your tent … For you will spread abroad to the right and to the left, and your offspring will possess the nations.” —Isaiah 54:2–3

Paul quotes this prophecy in Galatians 4:27 to describe the children of the heavenly Jerusalem. The new-covenant offspring includes Gentiles gathered into Abraham’s family through faith in Christ.

A Righteous People in an Everlasting Land

Isaiah 60 unites righteousness and permanent possession of the land.

“Your people shall all be righteous; they shall possess the land forever, the branch of my planting, the work of my hands, that I might be glorified.” —Isaiah 60:21

The crucial problem is righteousness. Israel could not remain in the land because it was unrighteous. The servant therefore makes the many righteous, enabling them to possess the eschatological inheritance forever.

The Anointed Servant and the Everlasting Covenant

Isaiah 61 announces the Spirit-anointed servant who brings good news, liberty, comfort, restoration, and everlasting joy.

“The Spirit of the Lord GOD is upon me, because the LORD has anointed me to bring good news to the poor.” —Isaiah 61:1

Jesus declares in Luke 4 that this prophecy is fulfilled in his ministry. Isaiah continues by describing the rebuilding of ruins, the inclusion of foreigners, a priestly people, and an everlasting covenant.

“I will faithfully give them their recompense, and I will make an everlasting covenant with them. Their offspring shall be known among the nations.” —Isaiah 61:8–9

The New Covenant in Jeremiah

Jeremiah 31: The Foundational New-Covenant Prophecy

Jeremiah 31 explicitly names the new covenant and contrasts it with the covenant made when God brought Israel out of Egypt.

“Behold, the days are coming, declares the LORD, when I will make a new covenant with the house of Israel and the house of Judah, not like the covenant that I made with their fathers … my covenant that they broke.” —Jeremiah 31:31–32

The contrast is with the Mosaic covenant, not the Abrahamic covenant. The old covenant was breakable; the new covenant is internally effective and rests on divine promise.

“I will put my law within them, and I will write it on their hearts. And I will be their God, and they shall be my people.” —Jeremiah 31:33

The covenant includes both regeneration and justification:

“They shall all know me, from the least of them to the greatest … For I will forgive their iniquity, and I will remember their sin no more.” —Jeremiah 31:34

The chapter continues with the fixed order of creation, the permanence of Israel’s offspring, and the rebuilding of the holy city. These images signify the unbreakable permanence of the eschatological people of God.

Jeremiah 32: The Everlasting Covenant

Jeremiah 32 is spoken while Babylon is closing in on Jerusalem. At the moment when the Mosaic curse is falling, God promises regathering, inward renewal, and an everlasting covenant.

“I will give them one heart and one way, that they may fear me forever … I will make with them an everlasting covenant, that I will not turn away from doing good to them.” —Jeremiah 32:39–40

God not only commands faithfulness; he produces it.

“I will put the fear of me in their hearts, that they may not turn from me.” —Jeremiah 32:40

The new covenant is unbreakable because God commits himself both to doing good to his people and to preserving them in covenant faithfulness.

The Righteous Branch

Jeremiah also identifies the Davidic king through whom the restoration will come.

“I will raise up for David a righteous Branch, and he shall reign as king and deal wisely … And this is the name by which he will be called: ‘The LORD is our righteousness.’” —Jeremiah 23:5–6

The restored people dwell securely because their king supplies the righteousness they lack.

The New Covenant in Ezekiel

Cleansing, a New Heart, and the Spirit

Ezekiel 36 describes the restoration as an act God performs for the sake of his holy name. He gathers his people, cleanses them from idolatry, gives them a new heart, places his Spirit within them, and causes them to obey.

“I will take you from the nations and gather you from all the countries and bring you into your own land … I will give you a new heart, and a new spirit I will put within you.” —Ezekiel 36:24, 26

The restored land is described as a renewed Eden:

“This land that was desolate has become like the garden of Eden.” —Ezekiel 36:35

The connection runs from Eden to Canaan and from Canaan to the new creation. Adam was expelled from Eden for covenant disobedience; Israel was expelled from the land for the same reason. The new covenant restores God’s people to the true Eden by giving them cleansing, righteousness, and the Spirit.

Resurrection, the Davidic King, and the Covenant of Peace

Ezekiel 37 portrays exiled Israel as a valley of dry bones. The restoration is a resurrection from covenant death. God gives breath to the slain nation and raises it into a living people.

The second half of the chapter gathers the three elements of the kingdom: people, land, and king.

“My servant David shall be king over them, and they shall all have one shepherd … They shall dwell in the land that I gave to my servant Jacob … and David my servant shall be their prince forever.” —Ezekiel 37:24–25

The covenant is called both a covenant of peace and an everlasting covenant.

“I will make a covenant of peace with them. It shall be an everlasting covenant with them … and will set my sanctuary in their midst forevermore.” —Ezekiel 37:26

The goal is God’s permanent dwelling with his people.

“My dwelling place shall be with them, and I will be their God, and they shall be my people.” —Ezekiel 37:27

Revelation 21 applies this promise to the new heavens and new earth.

The Covenantal Triangle and the Interpretation of Prophecy

The prophetic books form a bridge between the collapse of the Mosaic order and the coming of Christ. They use the categories of the Abrahamic promise and the first-level kingdom to announce the second-level fulfillment. This covenantal triangle is the engine driving the narrative arc of redemptive history:

1. God promises the kingdom to Abraham.
2. Israel fails under the Mosaic covenant and is expelled from the land.
3. God fulfills the Abrahamic promise through Christ in the new covenant.

This structure also explains why prophetic language should not be restricted to a merely earthly, national, and literal restoration. The prophets speak better than they fully understand because the Holy Spirit, the divine author, intends a fulfillment that surpasses the immediate horizon of the human author.

“The prophets who prophesied about the grace that was to be yours searched and inquired carefully … It was revealed to them that they were serving not themselves but you.” —1 Peter 1:10–12

The Achilles’ Heel of Dispensationalism

Classical dispensationalism combines two principles that create a serious difficulty for its doctrine of the new covenant.

First, it defines literal grammatical-historical interpretation so that the meaning of prophecy is limited to what the human author could have intended in his historical setting. It rejects a sensus plenior, a fuller divine intention that exceeds the prophet’s understanding.

Second, it treats Israel and the church as two distinct peoples of God with different destinies. Israel is earthly and national, with a land promise and an earthly kingdom. The church is heavenly and parenthetical, a mystery supposedly unknown to the Old Testament prophets.

Applied to Jeremiah 31:31, these principles seem to require that the new covenant belong exclusively to ethnic Israel and be fulfilled only in a future millennial restoration.

“Behold, the days are coming … when I will make a new covenant with the house of Israel and the house of Judah.” —Jeremiah 31:31

John Nelson Darby argued that if the church was a mystery unknown to the prophets, Jeremiah’s new covenant could not concern the church. Some contemporary classical dispensationalists accordingly state that the church has no legal relationship to or participation in the new covenant.

The problem is that the New Testament explicitly identifies the church as the present recipient of the new covenant.

Failed Attempts to Separate the Church from the New Covenant

Two New Covenants

Lewis Sperry Chafer proposed two distinct new covenants, one for Israel and another for the church. Charles Ryrie and John Walvoord initially held this view but later abandoned it.

This solution fails because Hebrews explicitly quotes Jeremiah 31 and applies that covenant to Christ’s priestly ministry and the Christian community. It also fails at the Last Supper, where Jesus connects the forgiveness of sins in his blood with Jeremiah 31:34.

Partial Fulfillment in the Church

Progressive dispensationalism teaches that the new covenant is partially fulfilled in the church but will be completely fulfilled in a future millennium. This acknowledges the New Testament evidence but also implicitly admits a spiritual, second-level fulfillment that exceeds a strictly literal interpretation of Jeremiah’s words.

Classical dispensationalists therefore object that progressive dispensationalism has compromised the literal grammatical-historical method.

Limited Soteriological Participation

A common contemporary classical view distinguishes the covenant’s actual eschatological fulfillment for Israel from limited soteriological benefits enjoyed by the church. The church supposedly receives these benefits indirectly through its relationship with Christ, the mediator of Israel’s covenant, but is not itself a covenant party.

This distinction minimizes what Hebrews presents as the very heart of the new covenant. Christ’s sacrifice, resurrection, ascension, priesthood, intercession, and the believer’s access to God are not peripheral benefits scattered from a covenant belonging to someone else. They are the substance of the covenant itself.

Three New Testament Proofs That the Church Receives the New Covenant

Hebrews 8–10

Hebrews 8 quotes Jeremiah 31:31–34 at length and declares that Christ is the mediator of a better covenant established on better promises. Hebrews 9:15 calls him the mediator of the new covenant, and Hebrews 10 interprets the forgiveness promised in Jeremiah as the result of Christ’s once-for-all sacrifice.

The entire argument of Hebrews depends on the new covenant being presently operative for Christians. The audience is tempted to return to Jewish temple worship. The author responds that the Levitical system was only a shadow. Christ has offered the final sacrifice, entered the heavenly sanctuary, and given his people direct access to God. Were the new covenant still awaiting its actual fulfillment in a future national Israel, the author’s warning against returning to the temple would collapse.

Jesus at the Last Supper

Jesus explicitly inaugurates the new covenant in the presence of his disciples.

“This cup that is poured out for you is the new covenant in my blood.” —Luke 22:20

Paul records nearly identical words:

“This cup is the new covenant in my blood.” —1 Corinthians 11:25

Matthew and Mark use the expression “blood of the covenant,” echoing the ratification of the Mosaic covenant in Exodus 24:8.

“This is my blood of the covenant, which is poured out for many for the forgiveness of sins.” —Matthew 26:28

The reference to forgiveness alludes directly to Jeremiah 31:34. The reference to blood signifies covenant-ratifying death. Jesus is therefore claiming that his death inaugurates Jeremiah’s new covenant.

The repeated phrase “for you” is also decisive. His body is given and his blood poured out for the disciples and, by extension, for all who believe in him. The covenant is not merely a future arrangement for another people; it is the covenantal meaning of Christ’s death for the church.

Paul as a Minister of the New Covenant

Paul describes his apostolic ministry to Gentile churches as a ministry of the new covenant.

God “has made us sufficient to be ministers of a new covenant, not of the letter but of the Spirit.” —2 Corinthians 3:6

Paul contrasts his ministry with Moses’ ministry of the old covenant. The contrast is therefore between the new covenant and the Mosaic covenant, not between the new covenant and Abraham. The new covenant ministry is the present preaching of the gospel to Jews and Gentiles.

Jesus’ Entire Ministry as New-Covenant Fulfillment

The Last Supper is the climax of a ministry that had been announcing new-covenant fulfillment from the beginning.

“The time is fulfilled, and the kingdom of God is at hand.” —Mark 1:15

Jesus applies Isaiah 61 to himself:

“Today this Scripture has been fulfilled in your hearing.” —Luke 4:21

His miracles enact Isaiah’s restoration promises.

“Then the eyes of the blind shall be opened, and the ears of the deaf unstopped; then shall the lame man leap like a deer.” —Isaiah 35:5–6

The twelve disciples represent the restored twelve tribes. The cleansing of the temple announces both judgment upon the old order and the building of the new temple. Jesus’ preaching, healings, exorcisms, gathering of disciples, death, and resurrection are all aspects of the promised restoration of Israel in the new covenant.

Continuity and Discontinuity

A major theological question remains. If the new covenant promises regeneration and justification, does that imply that Old Testament believers lacked a new heart and the forgiveness of sins? Scripture clearly teaches otherwise. Abraham was justified by faith, and the Old Testament saints were regenerated and saved through Christ.

The debate between Johannes Cocceius and Herman Witsius illustrates the difficulty. Cocceius emphasized discontinuity between the old and new economies. Witsius insisted that the same Christ bestowed true saving benefits on believers under the Mosaic economy, even though those benefits were administered through types and shadows.

“Christ, who was the same yesterday and today, bestowed on believers even under the Mosaic economy true benefits, in and with the typical.” —Herman Witsius

Witsius explained that Hebrews does not contrast the new-covenant administration of the Covenant of Grace with the earlier Abrahamic administration of that same covenant. Rather, it contrasts the Covenant of Grace in its full efficacy with the national covenant made at Sinai.

The benefits of Christ’s death belong to all the elect from the beginning to the end of the world. Old Testament believers possessed forgiveness, regeneration, justification, and the hope of eternal life. Yet they possessed these benefits in anticipation of an atonement not yet historically accomplished.

The Real Defects of the Old Covenant

Although Old Testament believers were truly saved, the old covenant was genuinely inferior. Witsius identified several defects.

First, the fathers did not have the cause of salvation present and accomplished. Christ had not yet come in the flesh, fulfilled the law, offered the final sacrifice, risen, and entered heaven.

Second, the old economy was obscure. The gospel was present, but hidden under types, ceremonies, sacrifices, and shadows.

Third, it was marked by rigor and severity. The national law covenant imposed temporal judgments and strict sanctions.

Fourth, Israel lived in bondage under repeated ceremonies. The sacrifices pointed evangelically to Christ, but their repetition also had a legal and condemning function.

“In these sacrifices there is a reminder of sins every year.” —Hebrews 10:3

The annual Day of Atonement did not simply announce forgiveness. It forced Israel repeatedly to remember its uncleanness and the continuing inadequacy of animal blood.

Fifth, the old order fostered a spirit of bondage because the nation remained under the typological republication of the works principle.

Sixth, the gifts of grace were given in a more limited measure. The Spirit was truly active but not yet poured out with new-covenant fullness.

Seventh, these limitations stirred an ardent longing for a better condition and for the coming Messiah.

Vos on the Inferiority of the Old Covenant

Geerhardus Vos highlights three additional contrasts in Hebrews.

First, the old covenant was earthly. Its sanctuary, priesthood, sacrifices, and inheritance belonged to the earthly and typological realm.

Second, it was fleshly, material, and external. Its regulations concerned physical descent, ceremonial cleanness, food, washings, and access to a man-made sanctuary.

Third, it was weak and ineffectual. It made nothing perfect because it could not bring the worshiper into final, eschatological access to God.

The Unique Benefits of the New Covenant

An Unbreakable Promise Covenant

The Mosaic covenant was a law covenant and was broken by Israel. The new covenant is a promise covenant in continuity with Abraham. God guarantees its saving fulfillment.

“Not like the covenant that I made with their fathers … my covenant that they broke.” —Jeremiah 31:32

The Law Written on the Heart

The promise of Jeremiah 31:33 fulfills Deuteronomy 30:6. God does not merely command obedience externally; he renews the heart by his Spirit so that his people love him and begin to walk in his ways.

“They Shall All Know Me”

“They shall all know me, from the least of them to the greatest.” —Jeremiah 31:34

This promise should not be interpreted to mean that every visible member of the church is necessarily regenerate. Hebrews 10:29 describes an apostate as one who was sanctified by the blood of the covenant, showing that covenant membership and final salvation are not identical.

The promise reaches its exhaustive fulfillment only in the eschaton, because Jeremiah also says that no one will need to teach his neighbor. Teaching plainly continues in the present church.

“When the perfect comes, the partial will pass away.” —1 Corinthians 13:10

Nevertheless, the promise has an inaugurated fulfillment now. The new covenant is not a national covenant embracing an entire civil people by physical descent. The church is gathered from the world as a community of professing believers and their children, and discipline is exercised against open unbelief. It remains mixed, but it is more pervasively marked by the knowledge of God than national Israel was.

Jeremiah’s phrase “from the least to the greatest” can describe something pervasive without requiring that it be exhaustively true of every individual (Jer. 6:13; 8:10; 42:1, 8; 44:12).

Sins Remembered No More

The forgiveness promised in Jeremiah 31:34 means more than the availability of personal pardon. Hebrews interprets it redemptive-historically as the accomplishment of the final atonement.

“I will remember their sins and their lawless deeds no more.” —Hebrews 10:17

The author immediately concludes:

“Where there is forgiveness of these, there is no longer any offering for sin.” —Hebrews 10:18

Old Testament believers were forgiven, but the sacrifice securing that forgiveness had not yet been offered in history. Under the new covenant, Christ has actually accomplished eternal redemption. The repeated offerings have ceased because the final offering has been made.

The Resurrected Christ in the Heavenly Sanctuary

Christ not only died; he rose and ascended. As the great high priest, he entered the true heavenly sanctuary and sat down at God’s right hand. He therefore achieved the “perfection” that the old covenant could not supply: final covenantal standing and unrestricted access to God.

A Great High Priest and Covenant Guarantor

Christ is both mediator and guarantor of the new covenant. His priesthood is permanent, his sacrifice complete, and his intercession unceasing. The covenant cannot fail because its blessings depend on his finished work and continuing heavenly ministry.

All the Saints Made Perfect Together

Hebrews 11 explains that the Old Testament saints truly lived and died in faith, yet did not receive the promised perfection apart from the church.

“All these, though commended through their faith, did not receive what was promised, since God had provided something better for us, that apart from us they should not be made perfect.” —Hebrews 11:39–40

When Christ completed the atonement and entered heaven, all the elect—those who lived before Christ and those who live after him—were made perfect together in him. The saints before Christ possessed salvation by promise; through Christ’s historical work, the entire people of God received the accomplished reality.

Unlimited Access to the Heavenly Temple

The new covenant brings believers to the true Mount Zion.

“You have come to Mount Zion and to the city of the living God, the heavenly Jerusalem … and to the spirits of the righteous made perfect, and to Jesus, the mediator of a new covenant.” —Hebrews 12:22–24

The church’s Lord’s Day worship is therefore a foretaste of heavenly worship. Christians do not merely gather for instruction and song. Through Christ, they participate by faith in the heavenly assembly, approach God’s throne, join the angels and perfected saints, and worship in the sanctuary opened by the blood of the new covenant.

Conclusion

The new covenant is both continuous with the Covenant of Grace and gloriously new in relation to the Mosaic order. It fulfills the promise to Abraham, answers the failure of Israel under the law, and establishes the everlasting kingdom through Christ.

Old Testament believers received the true benefits of Christ in anticipation, but they lived before the cause of salvation was historically present and completed. The new covenant brings the reality itself: Christ has obeyed, suffered, risen, ascended, entered the heavenly sanctuary, and secured eternal redemption.

The law is written on the heart. Sin is remembered no more. The Spirit has been poured out. Jews and Gentiles are gathered into one people. The final sacrifice has been offered. The great high priest intercedes in heaven. All the saints are made perfect together, and the church has unrestricted access to the presence of God. This is why the new covenant is the everlasting covenant and why no covenant can ever replace it.
