The Misc. Laws and Laws of Sexual Immorality
Deuteronomy 22 presents a body of Mosaic legislation covering miscellaneous civil duties and laws governing sexual morality, each rooted in the moral law summarized in the Ten Commandments. The first half of the chapter (verses 1–12) addresses property rights, gender distinction, ecological stewardship, safety precautions, and ceremonial mixtures — all concrete applications of the love command and the Decalogue to life in covenant community. The second half (verses 13–30) addresses premarital unchastity, adultery, and the critical distinction between the rape of a betrothed woman and the seduction of a consenting single woman, a distinction obscured by some English translations but essential to a fair reading of the text. Throughout, the threefold division of the law — moral, ceremonial, and judicial — provides the lens for identifying what carries permanent moral weight, what was fulfilled in Christ, and what expired with the Israelite commonwealth while leaving principles of general equity for civil application.
Deuteronomy 14:1-29 - Laws of Death, Diet, and Tithing
Deuteronomy 14 regulates mourning rites, dietary practices, and tithing for Old Covenant Israel — not as arbitrary impositions but as expressions of a holy people set apart by God from the nations around them. The chapter's controlling logic is covenantal identity: because Israel bore the status of God's firstborn son, every dimension of daily life, from the menu to the method of mourning, was to reflect that consecration. The dietary laws, now abrogated under the New Covenant as ceremonial law fulfilled in Christ, nevertheless carry a permanent New Covenant counterpart: the people of God are still to be distinguished from the world in holiness, presenting their bodies as living sacrifices. The tithing section closes the chapter with a call to generous, joyful giving that cares for the Levite, the stranger, the fatherless, and the widow — a call that carries into the New Covenant era as well.
2LCF Chapter 22 - Of Religious Worship and the Sabbath Day, Part 2
The perpetual moral obligation of the Christian Sabbath is grounded not in Sinai alone but in the creation ordinance of Genesis 2, where God blessed and sanctified the seventh day as a reflection of his own divine perfections. The 1689 London Baptist Confession of Faith chapter 22, paragraphs 7 and 8, frames the Sabbath as a positive-moral commandment — moral in its trans-covenantal, creation-rooted character, and positive in its covenantal form, shifting from seventh-day to first-day observance upon the resurrection of Christ as the inauguration of the new creation. The day belongs to God before it belongs to man: the governing question is not what may be avoided on the Lord's Day, but how near to God the worshipper may draw. Paragraph 8 calls for whole-souled preparation, rest from works, words, and thoughts entangled in worldly concerns, and the filling of the day with public and private worship, works of necessity, and works of mercy.
2LCF Chapter 22 - Of Religious Worship and the Sabbath Day
The regulative principle of worship — the doctrine that God alone prescribes the acceptable manner of his own worship — is the controlling theme of 2nd London Baptist Confession of Faith chapter 22, paragraphs 1 and 2. Drawing on Deuteronomy 12:29-32, 1 Timothy 3:14-15, Hebrews 12:18-29, and the narrative arc of Exodus through Leviticus, this study argues that Scripture consistently restricts corporate worship to what God commands, forbidding both addition and subtraction, across both the Old and New Covenants. The contrast between Leviticus 9 (divine approval) and Leviticus 10 (divine judgment on Nadab and Abihu) illustrates that coloring outside the lines God has drawn in worship carries deadly consequences. The practical application presses hearers to reject the normative principle of worship — the view that anything not expressly forbidden is permitted — in favor of the regulative principle: in worship, do only what God commands, with reverence and godly fear.
The Central Demand of the Covenant
Deuteronomy 10 presents the central demand of the Mosaic covenant — that Israel fear, love, and serve the Lord with all their heart and soul — set against the backdrop of the golden calf incident and the covenant's renewal. The sermon traces this demand from its roots in Deuteronomy 10:12–13 through its echoes in Genesis 18, Proverbs 21, Hosea 12, Zechariah 7, Micah 6, and Matthew 23, demonstrating that obedience rooted in heart religion has always been God's requirement of His people. The threefold division of the law is expounded, with the moral law established as perpetually binding while the ceremonial law finds its fulfillment in Christ and the judicial law expires with the Israelite theocracy. The sermon closes by pressing believers to hold fast to God, keeping His law not as a means of justification but as the pattern for sanctification purchased by Christ, the true Israel who alone fulfilled the covenant.
Ask FGBC #63: What is Baxterianism?
Baxterianism, drawn from the teaching of 17th-century minister Richard Baxter, replaces the Reformed doctrine of justification by faith alone with a scheme in which God justifies the believer on the ground of evangelical obedience to a relaxed 'law of the gospel.' This Q&A exposition identifies Baxterianism as a conflation of justification and sanctification, a departure from the imputation of Christ's active and passive obedience, and an implicit relaxation of the moral law — errors addressed directly by 1689 LBCF chapters 11, 13, and 19. The discussion grounds its critique in Galatians 2:16 and the consistent witness of Paul that sinners are justified by faith alone, not by any human obedience, through the sole and finished work of Christ.
Review Of Israel's Rebellion
Deuteronomy 9 confronts Israel's temptation to attribute their inheritance of the promised land to their own righteousness, and Moses systematically dismantles that presumption. The chapter divides into the anticipation of the conquest (vv. 1–6) and a recapitulation of Israel's wilderness rebellions (vv. 7–29), each episode confirming that Israel stood not by merit but by the sovereign mercy of God and the faithfulness of his covenantal promises to Abraham, Isaac, and Jacob. Moses's intercessory prayer at the chapter's close models covenant pleading that appeals not to Israel's worthiness but to God's glory, his sworn word, and the redemption he himself accomplished. The passage calls God's people in every era to forsake self-righteousness and rest entirely on divine grace.
Ask FGBC 69: Is the Threefold Division of the Law Biblical?
The threefold division of the law — moral, ceremonial, and judicial — is examined as a biblically grounded framework rooted not in Westminster Assembly invention but in the canonical structure of Scripture itself, traceable through the patristics and medieval scholastics. The discussion distinguishes natural or moral law (written on the heart by virtue of creation) from positive laws that are covenantally bounded and therefore terminable, using circumcision, dietary laws, and the Sabbath as test cases. The conversation addresses how the apostolic hermeneutic applies the moral principle behind positive laws (such as the ox-muzzling text) without collapsing into theonomy. Listeners are pressed to engage the exegetical evidence rather than dismissing the framework as "too tidy."
2LCF Chapter 19 - Of the Law of God
What role does the law of God play for the Christian now that Christ has come and the old covenant has been superseded? This confession-study exposition of 2LCF Chapter 19 works through seven paragraphs on the law of God, distinguishing moral universals from positive precepts, tracing the threefold division of the law (moral, ceremonial, judicial), establishing the creational and trans-covenantal abiding validity of the moral law, and demonstrating its divinely designed obsolescence in its ceremonial and judicial aspects. The three uses of the moral law — civil, pedagogical, and normative — are then applied to the Christian life, with Christ's active and passive obedience shown to be the only ground of righteousness before God.
The Central Confession of Israel's Faith
The Shema of Deuteronomy 6:4 — 'Hear, O Israel, the Lord our God, the Lord is one' — is examined as the central confession of Old Covenant Israel's faith, carrying both theological and polemical force for a people about to enter a land saturated with polytheism and syncretism. The sermon traces the purpose of God's commandments (obedience secured tenure in the land), the theological content of the Shema (divine unity of singularity and simplicity, and its compatibility with Trinitarian confession), and the fitting response of wholehearted love toward the one living and true God. The application presses New Covenant believers to the same totality of devotion — presenting themselves as living sacrifices — grounded in the redemption God has accomplished in Christ, the true Israel who kept the covenant His people perpetually broke.
The Conclusion of the Decalogue
Deuteronomy 5:22–33 records Moses rehearsing the original giving of the law at Sinai, and this exposition draws out the divine origin, authority, comprehensiveness, finality, and permanence of the Decalogue as the trans-covenantal moral law of God binding on all men in every age. The threefold use of the law — civil, pedagogical, and normative — is traced through the New Covenant, with the imputed righteousness of Christ received by faith as the only ground of justification. The people's terror at the theophany on Sinai is commended as the proper response to God's majesty, and the sermon presses the distinction between slavish fear that flees from God and filial fear that flees to Him, urging the congregation to recover a robust doctrine of divine transcendence in their worship.
The Tenth Commandment
The Tenth Commandment's prohibition against coveting addresses not the external act but the internal disposition of the heart, making it the capstone over all the other commandments. Covetousness — the inordinate desire for anything belonging to one's neighbor — is at root an act of discontentedness with God's sovereign allotment and a form of idolatry, placing the creature above the Creator. The sermon works through the threefold use of the moral law: its civil function, its pedagogical role in driving sinners to the cross, and its normative function in calling the redeemed to diligent watchfulness over heart and soul.
The 5th Commandment
The fifth commandment — 'Honor your father and your mother' (Deuteronomy 5:16) — demands far more than a recipe for happy families; it is a covenantal obligation rooted in God's own authority and binding on every generation. This study examines the command under three heads: its explanation (the Hebrew word for 'honor' connoting weightiness and reverence), its scope (extending beyond the family to all superior-inferior relationships in church, workplace, and commonwealth), and its sanction (from the rod of correction in Proverbs to the capital sentence of Deuteronomy 21). The promise appended to the command — long life and general wellbeing — is understood as a principle of divine providence, not an absolute guarantee, and the study closes with the duty of superiors to govern those beneath them in a godly and nurturing way.
Positive Law vs. Moral Law: Understanding The Sabbath
The fourth commandment contains both a moral element and a positive-law element. The moral element — that one day in seven is owed to God in worship — is binding on all creatures by nature. The positive element — which specific day — is determined by the covenant one stands in: Saturday under the old covenant, Sunday under the new, the latter established by Christ's resurrection on the first day of the week. This distinction answers why the church's day of worship changed without abandoning the creational obligation to Sabbath rest.
The Fourth Commandment, Part 3
Hebrews 4:9's use of the word 'Sabbatismos' — Sabbath-keeping as a practice to be observed — anchors the argument that a weekly Sabbath rest remains binding on the New Covenant people of God. The sermon traces the theological rationale for the day-change from Saturday to Sunday through the resurrection of Christ, arguing that the Son's rest from the work of new creation mirrors the Father's rest from the work of creation. Three alleged anti-Sabbatarian texts — Romans 14, Galatians 4, and Colossians 2 — are examined in turn and shown to address Jewish ceremonial calendar observances, not the moral fourth commandment. The burden of proof, the speaker argues, lies with those who would remove one commandment from the Decalogue, not with those who keep all ten intact.
The Fourth Commandment, Part 2
What does Jesus's ministry teach about the continuing obligation of the Sabbath commandment, and how does the resurrection determine which day Christians must observe? This study works through the Fourth Commandment (Deuteronomy 5:12–15) in its New Covenant application, examining Christ's relation to the law in Matthew 5:17–20, his correction of Pharisaic Sabbath-keeping in Matthew 12, and the testimony of all four Gospel accounts that the resurrection occurred on the first day of the week. The moral principle of one day in seven devoted to God is shown to be trans-covenantal and perpetual, while the positive-law element — which day — shifts from Saturday to Sunday with the resurrection of Christ, establishing what the 1689 London Baptist Confession calls the Christian Sabbath.
2LCF Chapter 22 - Of Religious Worship and the Sabbath Day, Part 1
The abiding validity of the Fourth Commandment is defended through a biblical theology of the Sabbath that traces the institution from creation through the old covenant. The sermon argues that Sabbath rest is grounded not in the Mosaic economy alone but in the creation ordinance of Genesis 2 and the redemption of Exodus, making it binding upon all humanity — not Jews only — as Christ himself teaches in Mark 2:27. The positive and moral character of the commandment is distinguished from its ceremonial and positive elements, with the day change to the Lord's Day deferred to the following session. Hearers are called to receive the Sabbath as the gift it is declared to be in Isaiah 58, not as a Judaizing imposition.
2LCF Chapter 4 - Of Creation
2LCF Chapter 4 expounds the doctrine of creation across three paragraphs, addressing what creation is, the triune God who creates, the nature and dignity of man as image-bearer, and the covenantal framework that gives creation its redemptive telos. The sermon argues that creation ex nihilo (qualified as God bringing forth all that is not God) and creation ex materia are distinct but complementary categories, and that divine immutability is preserved because no change or new perfection accrues to God through the act of creating. Ultimately, creation serves as the theatre within which God executes His eternal decree of redemption, bringing a multitude of elect sinners to glory through the perfect work of Jesus Christ.
The Second Commandment - Deuteronomy 5:8-11
The Second Commandment (Deuteronomy 5:8-11) prohibits both the making of images to represent God and the worship of those images — two distinct but related offenses against the infinitely simple, spiritual, and incomprehensible God. Because God cannot be captured in creaturely form, any visible representation of Him, including pictures or films of the Lord Jesus Christ, violates the commandment: the hypostatic union cannot be depicted by an artist's rendering, and Christ is to be set forth through preaching, not imagery. The positive demand of the commandment is worship regulated strictly by divine command — the regulative principle — which restricts the church to the elements God has prescribed in Scripture, excluding both the inventions of men and the traditions of Rome.
The Introduction to the Ten Commandments
The Ten Commandments stand apart from all other Mosaic legislation as the moral law of God — written by God himself on two tablets of stone, binding on all humanity in every age, and distinct from the ceremonial and judicial laws that have either been fulfilled in Christ or expired with the Old Covenant commonwealth. This study works through the introduction to the Decalogue in Deuteronomy 5, establishes the threefold division of the law, and then traces the threefold use of the moral law: its civil function as a restraint on sin in society, its pedagogical function in driving sinners to Christ, and its normative function as the pattern for the believer's sanctification. Four classical principles for interpreting the commandments are introduced to guide the series ahead, drawn from the Westminster Larger Catechism and Reformed exegetical tradition.
The Preface to the Ten Commandments
Deuteronomy 5:1–6 opens the Ten Commandments not with a command but with a declaration of divine redemption — 'I am the Lord your God, who brought you out of the land of Egypt, out of the house of bondage.' This study works through the summons to covenant obedience, the grace-grounded preface to the Decalogue, and the uniqueness of the moral law as trans-covenantal and abiding. The threefold division of the law — moral, ceremonial, and judicial — is examined through the confession, the prophets, the Gospels, and the epistles, equipping believers to distinguish what abides in the new covenant from what was fulfilled and abrogated in Christ.
The Necessity of Faithful Obedience, Part 2
Moses concludes the historical prologue of Deuteronomy with a programmatic warning to the second generation of Israel: idolatry will bring exile, but repentance will meet a merciful God. The sermon expounds Deuteronomy 4:25–49, tracing the consequences of covenant-breaking, the grounds of covenant mercy, and the incomparability of Israel's God as the only legitimate basis for obedience. The practical application presses the necessity of self-government, the danger of forgetfulness, and the trans-covenantal obligation of parents to pass covenant instruction to their children.
The Necessity of Faithful Obedience
Deuteronomy 4 closes Moses' historical prologue with an urgent exhortation to the second generation of Israel on the necessity of faithful covenant obedience before crossing the Jordan. The chapter's three movements — the necessity of obedience (vv. 1–8), the dangers of idolatry (vv. 9–31), and the incomparability of Israel's God (vv. 32–40) — are treated as an impassioned speech by a man who lived the history he recounts. Scripture's sufficiency is defended against every form of addition or subtraction, and the regulative principle of worship is grounded in God's self-revelation at Sinai as a consuming fire who receives no image.
The Sixth Commandment
The Sixth Commandment — 'You shall not murder' (Exodus 20:13) — addresses far more than the physical act of killing; it presupposes the dignity of every human being as an image-bearer of God and condemns unrighteous hatred of the heart. This sermon expounds the Hebrew word for murder, distinguishing it from lawful killing in capital punishment, just war, and self-defense, before pressing the command's indictment of abortion and euthanasia as violations of the sanctity of life. Jesus's teaching in Matthew 5 extends the commandment's reach to unwarranted anger and character assassination, and the three uses of the law — civil, pedagogical, and normative — frame both the church's public witness and the believer's ongoing sanctification. The sermon closes by insisting that the most faithful response to a death culture is to preach both the law and the cross of Christ.
Ask FGBC #27: Why the shift from Saturday to Sunday worship?
Why did Christian worship shift from the seventh day to the first day of the week? This Q&A response argues that Sunday observance is not an abolition of the fourth commandment but its new-covenant fulfillment, grounded in Christ's resurrection as the inauguration of new creation. The moral principle embedded in the fourth commandment — one day in seven set apart for the worship of God — transcends any particular covenant, while the positive element specifying which day shifts from Saturday to Sunday in light of Christ's finished work and rest. Drawing on Hebrews 4, the eighth-day Sabbath typology of the Old Testament, and the 1689 LBCF's treatment of the Lord's Day, the speaker urges believers to receive Sunday worship not as a burden but as the highest delight and privilege available to the people of God.
Ask FGBC #10: Why should only believers be baptized?
This Q&A episode addresses the Reformed Baptist argument that only professing believers are proper subjects of baptism. Drawing on the distinction between moral law and positive law, and grounding baptism firmly in the New Covenant rather than the Abrahamic covenant, the speaker argues that circumcision was an ordinance tied to a specific historical covenant now abrogated, and that its recipient-list cannot be transferred to baptism. The episode also traces the historical development of paedobaptism from pre-Reformation sacerdotalism to the covenantal argument codified in the Westminster Confession.
2LCF Chapter 19 - Of the Law of God
2 London Baptist Confession of Faith Chapter 19 sets forth a comprehensive doctrine of the law of God, tracing its origin in the covenant of works given to Adam, its threefold division into moral, ceremonial, and judicial law under the Mosaic economy, and its continuing role in the life of the New Covenant church. The moral law, rooted in creation and specially revealed at Sinai in the Ten Commandments, retains its binding force for all persons, while the ceremonial law finds its divinely designed terminus in the person and work of Christ, and the judicial law expired with the dissolution of the Israelite state. The sermon closes with a christological summary: Christ alone actively obeyed the whole law in the room and stead of the elect, bore the law's curse in his passive obedience, and now governs the hearts of his people by his Spirit according to that same law.
2LCF Chapter 16 - Of Good Works
Good works are only such as God has commanded in His holy word, proceeding from a heart purified by faith through the enabling power of the Holy Spirit — never the ground of justification, but the necessary fruit of it. This study of 2LCF Chapter 16 examines the definition, foundation, imperfection, non-meritorious nature, and acceptability of good works, set against Roman Catholic supererogation and any scheme that makes works a cause or increase of justification. Good works are accepted by God solely through union with Christ the mediator, and their purpose is the manifesting of thankfulness, the strengthening of assurance, the edifying of brethren, and the adorning of the gospel.
The Regulative Principle of Worship, Part 3
Deuteronomy 12:32 commands that nothing be added to or taken from what God has appointed for worship — a principle this sermon grounds in covenant theology and traces from the moral demands of natural law through the abrogation of the Old Covenant into the simplicity of New Covenant worship. The shift from Old Covenant to New Covenant is not a loosening of God's requirements but a fulfilment: the ceremonial positive law governing tabernacle, priesthood, sacrifice, and feasts has been abrogated by Christ, leaving the New Covenant church with the elements Christ himself has appointed — prayer, singing, Scripture reading, preaching, and the sacraments. The elements-and-circumstances distinction closes the argument: only what the divine Lawgiver has commanded in the New Covenant may govern the church's worship, and nothing may be added or taken away.
The Regulative Principle of Worship, Part 2
What authorizes the church to add, subtract, or substitute elements in corporate worship? Tracing the divine appointment of worship from Exodus and Leviticus through Deuteronomy 12:32 and into the books of Chronicles, this sermon demonstrates that Old Covenant Israel worshiped according to explicit divine command — not human creativity, cultural accommodation, or felt need. The same God who consumed Nadab and Abihu for offering strange fire, who filled Solomon's temple with his glory when worship was ordered according to his word, has not relaxed his standard in the New Covenant. The regulative principle is not a straitjacket but a guard against idolatry, and the New Covenant church is called to the same obedience: asking King Jesus what he has commanded, and doing that.
