Who Are the Heirs of the Promise?
Galatians 3:29 and 4:6–7 together answer the question of who truly inherits the promises made to Abraham: not those physically descended from him, nor those who observe Mosaic ceremonies, but those who are united to Christ by saving faith. The sermon traces the covenant-theological distinction between Abraham's physical seed and his spiritual seed, showing that membership in the covenant of grace is coextensive with those who receive the definite atonement of Christ. The Trinitarian shape of redemption — the Father sending the Spirit of the Son into the hearts of adopted sons — seals the argument, and the sermon draws out implications for believer's baptism and the enlarged liberty of the new covenant age.
Unpacking Covenant Theology: Tensions in Reformed Tradition
The relationship between the Mosaic Covenant and the Covenant of Works has generated significant tension within Westminster confessional theology, particularly around Meredith Kline's view of republication. While the broader Reformed tradition has historically accommodated a range of positions — including treating the Mosaic Covenant as a subservient covenant of works — the Westminster Confession narrows that range by specifying the Mosaic Covenant as an administration of the Covenant of Grace, creating a confessional problem for those who hold Kline's position. This exchange examines how confessional Presbyterians (including paedobaptists) navigate the resulting tension, with reference to OPC reports on republication.
Ask FGBC #14: How do we connect modern day Israel to Old & New Covenant Promises?
How should Christians understand the modern state of Israel, the Abrahamic and Davidic covenants, and the land promises in light of the New Testament? This Q&A exchange argues that the church is not a replacement for Israel but is the eschatological Israel of Old Testament prophecy — one people of God, Jew and Gentile together, united in Christ. Dispensationalism's two-peoples-of-God framework is evaluated and rejected on hermeneutical grounds, with Romans 11, the Davidic covenant, and the land promise examined in turn. The conversation broadens into the necessity of reading Scripture canonically and horizontally, the value of confessionalism, and the danger of allowing political rhetoric to distort biblical interpretation.
The Promise of Blessings and Cursing, Part 2
Leviticus 26:14–46 sets forth the covenant curses God threatened against Israel for breaking the Mosaic Covenant — a covenant of works — escalating through drought, wild animals, war, cannibalism, wholesale destruction, and exile. These curses came to historical fulfillment in the fall of the Northern Kingdom to Assyria in 722 BC, the fall of the Southern Kingdom to Babylon in 586 BC, and the destruction of Jerusalem by Rome in AD 70 — events prophesied in the Olivet Discourse and confirmed by Paul in 1 Thessalonians 2. The chapter closes with a promise of restoration conditioned on Israel's humble repentance and God's fidelity to the Abrahamic covenant. Believers under the New Covenant are freed from these covenant curses because Christ bore them fully, fulfilling the demands of the law and standing as the surety of a better covenant.
Leviticus 20 - the Death Penalty
Leviticus 20 catalogues capital offenses under the Mosaic law — idolatry, witchcraft, adultery, incest, homosexuality, and bestiality — and provides the occasion for a sustained biblical-theological treatment of the death penalty across the covenants. The study traces the authorization of capital punishment from the Noahic Covenant in Genesis 9 through the Mosaic legislation and into the New Covenant via Acts 25 and Romans 13, arguing that the death penalty remains a binding obligation upon civil magistrates. Romans 13 is read as the New Testament's clearest statement that the sword entrusted to the civil magistrate is God's instrument for executing wrath upon evildoers in history, not merely a sign of general authority. Hearers are called to think biblically about the proper and limited role of civil government, to resist the conflation of civil submission with capitulation to tyranny, and to uphold the abiding moral normativity of capital punishment for murder and other heinous crimes.
The New People of God, Part 1
What does it mean for the church to be built on Christ as a living cornerstone, and how does the Old Testament ground that identity? Expounding 1 Peter 2:6–8, this sermon traces the biblical-theological arc from Adam's failed dominion mandate in Genesis through Israel's typological history—law-giving, exile, and restoration—to the fulfilment of Isaiah's cornerstone prophecy in the Lord Jesus Christ. Israel's covenant history is shown to be a historical type of the cosmic reality: the broken covenant of works and its restoration by the Messiah, who is now building a global kingdom of redeemed image-bearers out of every tribe and tongue. Believers are called to marvel at God's sovereignty over history, over the kingdom of darkness, and over the unified message of Scripture that runs from Genesis 3:15 to the church as the true Israel of God.
Book introduction: The Mystery of Christ, His Covenant, and His Kingdom
Samuel Renihan introduces his book 'The Mystery of Christ, His Covenant, and His Kingdom,' explaining its origins in his seminary-era dissatisfaction with both pedobaptist and Baptist covenantal literature. He argues that historical particular Baptist covenant theology has been largely forgotten, and that modern Reformed Baptist literature has suffered from poor historical theology, excessive polemicism, and conclusions stated without premises. The book is structured by biblical theology rather than systematic theology, tracing three covenantal kingdoms — creation, Israel, and Christ — and contends that the concept of mystery in Paul is essential to a properly calibrated covenant theology that distinguishes the old covenants from the new covenant without collapsing the progressive development of divine revelation.
Genesis 9:1-17
Genesis 9:1–17 records the establishment of the Noahic covenant, a common grace covenant God makes with all flesh — universal in scope and perpetual in duration — to preserve the created order as the stage for the proclamation of the gospel. The passage divides into the covenant's stipulations (vv. 1–7) and its sign (vv. 8–17), with the stipulations covering the propagation of life, provision through diet, and the protection of life via capital punishment. The theological ground of the death penalty is the image of God: to murder a man is to assault the divine image, and the only commensurate response is execution by the civil magistrate. Romans 13:1–4 confirms that this mandate is not confined to the Mosaic economy but continues wherever civil government wields the sword as God's appointed avenger.
The Redeemer of God's Elect
Galatians 4:4–7 presents the person and work of the Redeemer in covenantal context: Christ's pre-existent eternal Sonship, incarnation, and role as mediator under the law provide the basis for redemption, adoption, and the indwelling of the Spirit. The sermon traces the obsolescence of the Mosaic covenant as designed and purposed by God, giving way to the full privileges of sons in the new covenant. The triune God is shown to be the sole initiator and executor of salvation — the Father sending the Son, the Son accomplishing redemption, and the Spirit sealing the adopted heirs. The sermon closes with a call to robust Trinitarian theology as inseparable from knowing and worshipping the God who saves.
Deuteronomy 30
Deuteronomy 30 is not merely a conditional exhortation at the edge of Canaan but a programmatic prophecy of what God would accomplish through exile, return, and ultimately the new covenant in Christ. The chapter's pivotal verse — the circumcision of the heart in verse 6 — is shown to be the fountainhead of the same promise later amplified by Jeremiah and Ezekiel and fulfilled in the regenerating work of the Spirit. The sermon traces five realities embedded in the future blessing (verses 1–14): the certainty of exile, the return to Yahweh, the divine initiative in restoration, the obedient response of the renewed heart, and the empowerment that Paul draws on in Romans 10 to describe the righteousness of faith. The practical summons in verses 15–20 — "choose life" — is then heard not as bare moralism but as a call to embrace the God who is himself the life and length of days of his covenant people.
A Brief Survey of Covenant Theology, Part 3
Why is the New Covenant necessary? This session of a three-part survey of covenant theology works backwards through redemptive history to answer that question with six interlocking reasons: the Mosaic Covenant was temporary and could not save; the Abrahamic Covenant promised but did not present Christ; Genesis 3:15 gave only the first promise of a mediator; Adam's failure as covenant head made Christ's obedience necessary; Adam broke the covenant of works God placed him under at creation; and the entire plan was purposed by God before the foundation of the world. The argument culminates in the claim that the New Covenant does not restore believers to Adam's pre-fall probationary state but brings them, through the last Adam, to the glorified status Adam forfeited and Christ secured.
A Brief Survey of Covenant Theology, Part 1
What is a divine covenant, and why does 'covenant theology' accurately describe the Bible's own architecture? This lecture — the first in a three-part survey — defines divine covenants as relational arrangements sovereignly initiated by God for man's benefit, with ways and means established by God alone to obtain the designated blessings. Drawing on Nehemiah Cox, 2 Samuel 7, Exodus 19, and Hebrews 10, the speaker demonstrates that both Testaments are covenantally structured documents: the Old Testament is the covenantal record for old covenant Israel, and the New Testament is the covenantal record for the new covenant church, both centering on Christ in his sufferings and glory. The lecture concludes that covenant theology is not an alien grid imposed on Scripture but the organic, Christocentric shape of biblical revelation itself, best interpreted by allowing the New Testament to illuminate the Old.
Deuteronomy 23
Deuteronomy 23 addresses the holiness of the covenant community through laws governing exclusion from the assembly of the Lord, ritual cleanliness in the military camp, and miscellaneous regulations for community life. The chapter's detailed and seemingly mundane stipulations — covering the castrated, the illegitimate, hostile ethnic groups, bodily waste, escaped slaves, cult prostitution, usury, vows, and gleaning rights — all flow from one unifying concern: Israel was a sanctified, set-apart people who were to reflect the character of the God who dwelt in their midst. These Old Covenant regulations, grounded in God's love for his covenant community, point toward the New Covenant expansion in which eunuchs, Gentiles, and all nations are called without restriction to enter the assembly of the Lord through the proclamation of the gospel.
Hagar, Sarah, and Covenant Theology
Galatians 4:21–31 presents Paul's allegorical argument from the two sons of Abraham — Ishmael and Isaac, Hagar and Sarah — to demonstrate that faith and law-keeping are mutually exclusive systems of approach to God. Paul maps Hagar onto the Mosaic covenant, first-century apostate Jerusalem, and the bondage of those who seek acceptance with God through legal works; he maps Sarah onto the covenant of grace, the heavenly Jerusalem, and the freedom of those who are justified by faith alone in Christ alone. New covenant membership belongs not to ethnic Israel as such, but to all — Jew and Gentile — who are united to Christ by sovereign grace, making them heirs of the promise given to Abraham. The sermon closes with a call to recognise false teaching as a form of persecution and to exercise church discipline against those who corrupt the gospel of free justification.
The Purpose of the Law
What is the purpose of the Mosaic law if the Abrahamic promise already secured salvation by faith? Galatians 3:19–25 forces this question, and the apostle Paul answers it not in terms of individual spiritual experience but in terms of redemptive history — the covenantal relationship between Sinai and the promise made to Abraham. The law was added to restrain and reveal sin, to preserve the biological and spiritual integrity of Israel until the promised seed, Christ, should come, functioning as a guardian or pedagogue over the covenant people until the fullness of time. The sermon closes by insisting that the expiration of the Mosaic covenant as a covenantal arrangement does not abolish God's moral law, which continues to bind believers as a pattern of sanctified life, while justification remains by faith alone in Christ alone.
The Priority of the Promise
The Abrahamic promise has absolute priority over the Mosaic law, and no subsequent covenant — not even the law given 430 years later — can annul, supplement, or condition what God confirmed in Christ before Moses ever appeared. Drawing on Galatians 3:15–18, this exposition works through Paul's human analogy of an irrevocable covenant, the identification of Christ as the singular seed in whom the promise is secured, and the mutually exclusive relationship between law and grace as grounds of inheritance. The practical weight falls on assurance: because the covenant of grace was made with Christ as its guarantor, neither Judaizing additions nor personal failure can undo what God has sovereignly sworn to fulfil for all who are in Christ.
Christ's Circumcision
Colossians 2:11–12 is frequently marshalled by paedobaptists to argue that baptism has replaced circumcision as the covenant sign and therefore ought to be administered to infants, but the passage cannot bear that weight. This sermon works through three preliminary observations — the structure of covenant theology, the relationship between circumcision and baptism, and the actual point of the passage — before exegeting verses 11–12 directly. The circumcision Paul describes is spiritual regeneration performed by Christ without hands, and baptism is its retrospective public sign, not a parallel to the prospective sign of physical circumcision given to Abraham's infant sons. The sermon closes with a sharp warning against any gospel that supplements Christ's finished work, insisting that justification is an alien, forensic righteousness imputed to the believer by grace alone through faith alone in Christ alone.
