The Ninth Commandment
The ninth commandment, 'You shall not bear false witness against your neighbor' (Deuteronomy 5:20), governs far more than courtroom testimony — it encompasses every form of lying, slander, backbiting, gossip, hypocrisy, and doctrinal heresy. Three grounds obligate God's people to truth-telling: God himself is truth, man bears God's image and his reputation is inviolable, and the stability of every social order depends on trust. The positive demand of the commandment calls believers to speak truth in all spheres of life, to discourage slander, and to resist the co-opting of humanist language that obscures biblical categories.
The Murder of the Preborn, Part 2
Exodus 21:22–25 grounds a biblical answer to the hardest objections raised against the prohibition of abortion. The sermon establishes that Scripture recognises exactly three instances of lawful killing — self-defense, just and necessary war, and capital punishment — and demonstrates that abortion satisfies none of them. The death penalty, far from contradicting the sanctity of life, is its strongest legal expression, grounded in the imago Dei of Genesis 9:6 and confirmed for the new covenant era by Romans 13:1–4. The church's response to abortion requires preaching the law of God without apology, loving neighbours through practical compassion, and declaring the gospel of the Lord Jesus Christ as the only remedy for guilt.
The Murder of the Preborn, Part 1
Exodus 21:22–25 provides the case-law context for examining what Scripture teaches about the sanctity of human life, the personhood of the preborn, and the biblical prohibition against abortion. The sermon grounds the argument against abortion in the imago Dei — man is not merely made in God's image but is the image of God, a dignity that extends from conception through old age and that no civil court or medical consensus can override. The preborn child is demonstrated to be a full human person through the consistent testimony of Genesis, the Psalms, the Prophets, and the New Testament, while the Lex Talionis of Exodus 21 establishes that taking the life of a child in the womb carries the full capital sanction reserved for murder. Hearers are called to understand, articulate, and act upon this biblical truth — in their prayer closets, at the ballot box, and in their own personal holiness.
Matthew 12:1-14
Jesus' conflicts with the Pharisees over Sabbath observance in Matthew 12:1–14 are not evidence that he abolished the fourth commandment, but that he cleared away the Pharisaic misinterpretation encrusting it. This Bible study is the second half of a biblical theology of the Sabbath, tracing the commandment through Christ's own teaching on the law (Matthew 5:17–20), the resurrection, the apostolic practice of first-day worship (Acts 20, 1 Corinthians 16, Revelation 1:10), and the eschatological Sabbath rest of Hebrews 4. The argument throughout is that the Decalogue is trans-covenantal, that Christ fulfilled rather than abrogated the fourth commandment, and that the shift from the seventh day to the first day reflects the same creational-redemptive logic — now centred on the risen Christ as head of the new creation.
The Lord of the Sabbath, Part 1
Matthew 12:1–8 presents the Pharisees' accusation that Christ's disciples violated the Sabbath, and Christ's five-fold response that exposes their misinterpretation of God's law. Working through the examples of David, the priestly ministry, the superiority of Christ over the temple, and the prophetic word of Hosea 6:6, the sermon argues that the Son of Man is Lord of the Sabbath — the one to whom the Sabbath institution pointed from its creation in Genesis 2. The Pharisees' legalism, built on the Mishnah's 39 categories rather than Scripture, condemned the guiltless and revealed both antinomian abuse of the law and a failure of mercy. The sermon closes by calling hearers to distinguish authorized Sabbath works (necessity, piety, and mercy) from the twin errors of Pharisaic legalism and contemporary license, and to rest in Christ himself as the fulfillment and Lord of the Sabbath.
Deuteronomy 33
Moses' final blessing over the tribes of Israel in Deuteronomy 33 frames every tribal blessing within a theology of God's incomparable glory, covenantal faithfulness, and gracious love for his people. The chapter opens with a theophany at Sinai — God appearing as king accompanied by his heavenly hosts to give his law — and closes with Israel's confession of Yahweh's uniqueness. The study moves verse by verse through Moses' farewell instructions (32:48–52) and the blessings on Reuben, Judah, Levi, Benjamin, and Joseph, showing how the structure of the chapter (introduction, blessings, conclusion) mirrors the pattern of covenantal blessing and how the Levitical office of teaching and sacrifice foreshadows the mediating work of Christ.
The Goodness of God's Law
Paul's claim in 1 Timothy 1:8 that 'the law is good if one uses it lawfully' confronts two recurring errors in the church: legalism, which perverts the law into a ladder of merit before God, and antinomianism, which banishes the law from the Christian life altogether. This sermon works through verses 8–11 to establish three things: the apostolic affirmation that the law is intrinsically good, the necessary qualification that it must be used lawfully, and Paul's explanation of its civil use — the restraint of outward wickedness — illustrated by a rehearsal of the Decalogue's second table. The threefold use of the law (civil, pedagogical, normative) is set within the framework of covenant theology and justification by faith alone, which together guard the church from both errors, and the sermon closes by pressing the pedagogical use upon the unconverted: look to Sinai, see your guilt, and flee to Christ alone.
The Bible and Abortion, Part 1
What does Scripture say about abortion, and does it offer a coherent case for the sanctity of unborn life? This sermon works through three interlocking biblical arguments: the sanctity of human life grounded in the imago Dei, the established personhood of the pre-born throughout both Testaments, and the specific prohibition against abortion implied in the case law of Exodus 21:22–25. The lex talionis applied to accidental premature birth demonstrates that God holds the life of the unborn equal in worth to the life of the mother, making intentional abortion a violation of the sixth commandment. The sermon closes by insisting that the only remedy for the guilt of a murderous culture is the gospel of Jesus Christ, who is a real Savior for real sinners.
Deuteronomy 20
Deuteronomy 20 sets forth three categories of principle governing Israel's holy warfare: a general call to fearlessness grounded in the presence and power of Yahweh, specific exemptions from military service, and regulations for engaging enemy cities. The chapter distinguishes between cities far from Canaan — to whom peace must first be offered — and the Canaanite nations under the ban, who were to be utterly destroyed lest they corrupt Israel's worship. Throughout, the text reveals a God who fights for His people, restrains their conduct in war by humanitarian concern, and warns that failure to execute the ban would produce exactly the idolatry Israel later fell into.
The Golden Rule
Matthew 7:12 — the Golden Rule — stands as the hinge of the Sermon on the Mount, summarizing the entire ethical instruction of chapters 5–7 in a single positive imperative: treat others the way you want to be treated. This sermon distinguishes the positive form of the rule from its negative rabbinic counterpart (Hillel's formulation), showing that the positive form not only restrains evil but actively promotes love — love defined not by sentiment but by obedience to the second table of the Decalogue. The preacher traces the Golden Rule through Matthew 22, Leviticus 19:18, Romans 13, and Galatians 5, arguing that antinomianism cannot survive an open Bible, and that the rule's comprehensiveness, perpetuity, and proactivity demand Spirit-empowered obedience that flows from the gospel, not toward it.
Seduction to Idolatry
Deuteronomy 13 confronts Israel — and the church — with three escalating scenarios of seduction to idolatry: the false prophet who performs genuine signs and wonders, the intimate family member who whispers in private, and the city that has given itself wholly over to apostasy. The sermon argues that the severity of the prescribed penalties is not barbarism but proportionate justice rooted in the holiness, jealousy, and justice of the God who redeemed Israel by sovereign grace — and that the New Testament, far from softening this standard, intensifies it in passages such as Galatians 1:8-9 and 1 Corinthians 16:22. Throughout, the preacher insists that the church today does not wield the civil sword, but must nonetheless take with utmost seriousness the danger of idolatry in all its forms — including the subtlest idol of self — and find refuge from it only in the cross of Christ.
Deuteronomy 11
Deuteronomy 11 brings Moses' extended introductory appeal to a close, pressing Israel with three requirements for obedience grounded in God's past redemptive acts, the goodness of the promised land, and the covenant blessings that await faithfulness. The chapter's repeated call to love and keep the commandments of Yahweh exposes the radical inability of sinful man and thereby magnifies the necessity of Christ, who alone kept the charge, statutes, judgments, and commandments always as mediator, head, and surety for his people. The chapter concludes with the solemn setting of blessing and curse upon Mounts Gerizim and Ebal, which bracket the entire legal code of chapters 12–26 and press the covenant choice before Israel. Christians are called to let God's past faithfulness, future inheritance, and covenantal promises serve as the engine of present obedience.
True Doctrine, Proper Conduct
Colossians 3:1–11 establishes that right belief and right conduct are inseparable: orthodoxy produces orthopraxy. Working through Paul's commands to seek the things above and to mortify sin, this exposition demonstrates that the theological incentives of union with Christ — past death to the old man, present hiddenness in God, and future appearance in glory — are the only sufficient foundation for holy living. The vice lists of verses 5–11, covering both sins of the flesh and sins of the tongue, are shown to flow from a disordered mind rather than a regenerate one, and behavior modification apart from the new birth is exposed as an inadequate remedy. The sermon closes with a call to look to Christ crucified as the only ground for both justification and transformed conduct.
The Fallen King and the Grace of God
David's catastrophic fall into adultery and premeditated murder in 2 Samuel 11–12 is the lens through which this sermon examines the nature of sin, its inevitable exposure before a holy God, and the sovereign grace that pursues and pardons even the most heinous transgressor. Working through four observations — the sin itself, the attempted cover-up, the divine verdict, and the Lord's response through Nathan — the exposition magnifies not David but Christ, the only King without blemish, whose finished work is the sole ground of forgiveness. The confession 'I have sinned against the Lord' and Nathan's immediate declaration 'the Lord has put away your sin' together demonstrate that intensity of repentance contributes nothing to atonement; pardon rests wholly on grace. Listeners are called to see themselves in David's cover-up, to abandon every attempt to hide transgression, and to come to Christ whose death is the only reason any sin can be put away.
The Sin of Abortion
Abortion is not primarily a political question but a theological one, grounded in the biblical doctrine that every human being bears the image of God from the moment of conception. This exposition of Exodus 21:22–25 argues that the case law of Israel assigns the full protections of lex talionis to the pre-born child, treating even accidental abortion as a capital offense — which renders intentional abortion an act of murder. The sermon also addresses the abortifacient mechanisms of certain contraceptives as an extension of the same ethical concern, and closes by directing those who bear guilt over past abortions to the forgiveness available in Christ.
The New Covenant
Jeremiah 31:31–34 contains the Old Testament's sole explicit use of the phrase 'new covenant,' and this sermon expounds its announcement, essential features, and fulfillment in Christ. Against the backdrop of Judah's covenant-breaking idolatry, God promises a covenant that is unbreakable, one that internalizes his moral law, grants saving knowledge of himself, and secures the definitive forgiveness of sin. The Hebrews quotation of Jeremiah 31 and Christ's own words at the Last Supper confirm that this covenant finds its ratification in the blood of Jesus, the surety and mediator of a better covenant. The sermon closes by drawing out the Reformed Baptist implication that new covenant membership — marked uniformly by regeneration, law-internalization, knowledge of God, and forgiveness — necessarily implies believers' baptism, and by calling the unconverted to seek that fountain open for sin and uncleanness.
Gospel Liberty and the Law of Love
Gospel liberty, rightly understood, is not freedom from responsibility but freedom for the service of God and neighbour. Expounding Galatians 5:13–15, this sermon argues that Paul is no antinomian: believers called to liberty are simultaneously called to fulfil the moral law through love, and the gospel of free justification is the very source of genuine sanctification, not its enemy. Four theological implications of Paul's appeal to Leviticus 19:18 are drawn out — Paul's rejection of antinomianism, the threefold distinction in the law, the continuity of the moral law from creation through Sinai into the new covenant, and the complementary rather than antithetical relationship of Spirit and law — before the sermon closes with a sober warning that biting and devouring within the church betrays a failure of gospel-wrought love. The congregation is exhorted to pursue loving service of one another as the God-appointed antidote to both legalism and licentiousness.
A Biblical View of Abortion
Exodus 21:22–25 presents a case of accidental premature birth caused by fighting men, and the lex talionis applied to any resulting harm — including harm to the child — establishes that the pre-born bear full legal and moral standing under the law of God. This sermon argues that abortion is first and foremost a theological issue, an assault on the imago Dei, and that the church is without excuse in its silence or ambiguity on this question. Drawing on texts from Genesis through the New Testament, the preacher demonstrates that the pre-born are persons from conception, that the civil use of God's law restrains even unregenerate society, and that the church must respond with weeping, prayer, witness, and gospel proclamation.
Biblical Womanhood in the Book of Proverbs, Part 2
Proverbs 31:10–31 presents the biblical mother not merely as a domestic figure but as a person of God-given influence, authority, and weighty responsibility. This expository treatment draws on the wider Proverbs corpus, the fifth commandment, and the Pauline household codes to argue that a Christian mother shapes her children through instruction, example, discipline, and love — all four of which are expressions of biblical obedience rather than sentiment. The sermon closes with a gospel-grounded application: the mother's standing before God rests on the finished work of Christ, which is precisely what frees her to pursue this calling faithfully and to repent when she falls short.
The Responsibility of Children
Colossians 3:20 addresses children as responsible members of the covenant community with a specific duty: to obey their parents in all things for the glory of God. This sermon expounds that command under two headings — as a religious commitment rooted in what is well-pleasing to the Lord, and as a requirement of God's moral law grounded in the Fifth Commandment (Exodus 20; Deuteronomy 5; Ephesians 6:1–3). The law's impossible demand is not softened but turned pedagogically toward the cross: children cannot perfectly obey or honor their parents, and that failure is meant to drive them to Christ, whose active obedience fulfilled all righteousness on behalf of sinners. Parents are therefore urged to present the law honestly, presume nothing about their children's regeneration, and cultivate homes where gospel ethics are visibly practiced.
The New Covenant
Jeremiah 31:31–34 announces a new covenant that surpasses every prior administration of the covenant of grace — Adamic, Noahic, Abrahamic, Mosaic, and Davidic — by guaranteeing what none of them could: an inviolable covenant secured not by human fidelity but by the covenant head, the Lord Jesus Christ. Four defining features mark the new covenant as genuinely new: the inviolability of its bond, the internalization of God's law upon the heart, the saving knowledge of God granted to every member, and the full and permanent forgiveness of sins. Against Federal Vision teaching, the sermon insists that new covenant membership is coextensive with salvation — those who fall away demonstrate they were never true members. Entry into this covenant is by grace alone, through faith alone, in Christ alone, who ratifies it in his own blood as the surety of a better covenant.
A Biblical View of Private Property
The eighth commandment — 'You shall not steal' (Exodus 20:15) — grounds a comprehensive biblical ethic of private property that reaches far beyond street crime into fraud, extortion, currency debasement, and even the withholding of tithes. This sermon works through the prohibition in its many forms, then sets out four theological reasons for the command rooted in God's sovereignty, man's dignity as image-bearer, and the positive law of Scripture. The exposition closes by calling hearers to diligent labor, charitable giving, and contentment — and by pointing thieves and extortioners alike to the justifying blood of Christ, under which such sinners have been washed and sanctified.
A Christian View of Abortion
Abortion is not a political question but a theological and ethical one, answered definitively by Scripture. This sermon works through the biblical case for the sanctity of human life from creation to law, grounds the personhood of the pre-born in texts from Genesis through Luke, and then expounds Exodus 21:22–25 to show that God's law affords full legal protection — including the lex talionis — to the unborn child and the mother alike. Christians are called to weep over this ongoing atrocity, to arm themselves with Scripture, to pray and witness faithfully, and to proclaim both the law that condemns and the gospel that saves to all who have participated in it.
The Lawful Uses of God's Law
The law of God is good when used lawfully — and Scripture identifies three distinct lawful uses that the church must recover. Drawing from 1 Timothy 1:8–11 and ranging across Romans, Galatians, and the Westminster Larger Catechism, this sermon exposits the threefold use of the law (civil, pedagogical, normative) as the historically Reformed framework for understanding law and gospel. The civil use restrains wickedness in society; the pedagogical use exposes sin and drives sinners to Christ; the normative use provides the regenerate with a pattern of holy conduct that the indwelling Spirit enables them to pursue freely. The central burden of the sermon is that stripping law from gospel preaching produces a generation that wants comfort rather than righteousness, and that a high view of the law is inseparable from a high view of the Redeemer.
Walking as Sons of God
Ephesians 5:1–21 sets out three responsibilities belonging to every adopted son and daughter of God: walking in love, walking in light, and walking in wisdom. Biblical love is not a feeling but a law-directed action patterned after Christ's self-sacrifice, measured by the Decalogue rather than sentiment. Walking in light means finding out what is acceptable to God through diligent study of Scripture, then living in such a way that righteousness exposes darkness. Walking in wisdom means hearing the Word of Christ and doing it — redeeming every opportunity in evil days, whether to advance the kingdom or to guard against the temptations a pagan culture presses upon the believer.
