The Inclusion of the Gentiles in God's Covenant
Ephesians 2:11–22 addresses the radical transformation of Gentile believers, who were once 'aliens from the commonwealth of Israel and strangers from the covenants of promise,' into full participants in the covenant of grace. The sermon traces three movements in the text: the former plight of Gentile unbelievers (vv. 11–12), their present reception through the blood of Christ (vv. 13–17), and the purchased benefits now belonging to them as fellow citizens, members of God's household, and living stones in his temple (vv. 18–22). Christ is shown to be the one who is peace, who makes peace through the cross by abolishing the ceremonial law's enmity, and who preaches peace through the apostolic gospel. The exposition concludes with a call to prize corporate worship as the special dwelling place of God Most High, in which Jewish and Gentile believers together form one temple indwelt by the Spirit.
2LCF Chapter 19 - Of the Law of God
The law of God — moral, ceremonial, and judicial — is the organising subject of 1689 London Baptist Confession chapter 19. This session works through all seven paragraphs, tracing the moral law from its inscription on Adam's heart at creation, through its codification at Sinai, to its perpetual obligation upon every human being under the new covenant. The threefold division of the law (moral, ceremonial, judicial) is carefully distinguished: the ceremonial law is abrogated in Christ, the judicial law has expired with the Israelite theocracy though its general equity retains moral usefulness, and the moral law binds all persons forever — not as a covenant of works, but as a rule of life that sweetly complies with the grace of the gospel. Believers are called to embrace the law as a delight, a tutor pointing to Christ, and a pattern for sanctification rather than a means of justification.
The Sixth Commandment
The sixth commandment, 'You shall not murder' (Deuteronomy 5:17), prohibits not only the external act of unlawfully taking human life but also the internal dispositions of hatred, unwarranted anger, and character assassination that Christ exposes in the Sermon on the Mount. The prohibition is grounded in the imago Dei: because every human being bears the image of God, to assault a human life is to assault the divine majesty itself. The sermon carefully distinguishes murder from lawful killing, defending the legitimacy of capital punishment, just war, and self-defense, while applying the command's positive obligation — the active promotion of life — to contemporary issues including abortion, euthanasia, and gossip.
The Fifth Commandment
The Fifth Commandment, 'Honor your father and your mother' (Deuteronomy 5:16), is the first commandment of the second table of the law and governs not merely the parent-child relationship but all relationships between superiors and inferiors in family, church, and civil society. The command to 'honor' (Hebrew: to treat as weighty and burdensome) carries covenantal significance for Israel and is extended by Paul to Gentile believers in Ephesians 6, demonstrating that the moral law transcends any particular covenantal administration. The sanction attached to its violation — from the rod and reproof of Proverbs to the death penalty of Deuteronomy 21 — underscores the gravity God assigns to lawful authority. Pedagogically, the commandment exposes the universal failure of all people to render perfect obedience and drives sinners to Christ, who alone fulfilled this word by continuing in subjection to Joseph and Mary throughout his earthly life.
The Fourth Commandment
The Fourth Commandment, as confessed in the 1689 London Baptist Confession chapter 22, binds all men in all ages to set apart one day in seven for the worship of God. This exposition of Deuteronomy 5:12–15 traces the Sabbath from its creation ordinance grounding in Genesis 2, through its Sinaitic rationale of creation and redemption, into its prophetic anticipation in Isaiah 56 and 58, and finally to its New Covenant fulfillment on the first day of the week as the Lord's Day. The sermon argues that the Sabbath's moral principle — one day in seven devoted to God — is permanent and continuous across the covenants, while the positive element (the particular day) shifts from Saturday to Sunday in light of Christ's resurrection. Hearers are called to receive the Sabbath not as a legalistic burden but as God's gift, and to guard equally against Pharisaic rigidity and antinomian dismissal.
2LCF Chapter 19 - Of the Law of God
The moral law of God — summarized in the Ten Commandments, written on the heart of man at creation, and codified at Sinai — remains perpetually binding on all persons, regenerate and unregenerate alike. This study of 2LCF Chapter 19, paragraphs 1, 2, 5, and 6 traces the law from its origin in the covenant of works with Adam through its threefold use (civil, pedagogical, and normative) for believers under the covenant of grace. Christ did not abolish the law but fulfilled it, thereby confirming rather than dissolving its authority. The session closes with a call to avoid antinomianism, to obey the law from proper gospel motives, and to delight in it as the revealed will of God.
Exodus 19-24
Exodus 19–24 presents the Old Covenant in concentrated form: a holy God descends on Sinai in storm theophany, sets forth the conditions of the Mosaic covenant, and binds Israel in blood to stipulations they prove incapable of fulfilling. The study moves through three units — the holiness of God (chs. 19–20), the Book of the Covenant with its judicial laws for a theocratic nation (chs. 21–23), and the ratification of the covenant in blood and covenant meal (ch. 24). Because the Old Covenant is conditional and Israel is faithless, the study drives toward Christ as the true Israel who fulfilled the covenant of works and the Mosaic stipulations alike, securing for his people the better covenant foreshadowed at Sinai.
The Preface to the Ten Commandments
The Ten Commandments are not a path to earned standing before God but the covenant stipulations of a God who has already redeemed his people — the indicative of grace always precedes the imperative of law. Expounding Deuteronomy 5:1–6, this sermon examines the summons to obedience Moses issues to the second generation on the plains of Moab, and then the preface to the Decalogue itself, showing that the identity and activity of the Lawgiver are the indispensable foundation for understanding why God's moral law binds his people. The threefold division of the law — ceremonial, judicial, and moral — is defended from the confessional Reformed tradition, and the abiding validity of the Decalogue in the new covenant is grounded in Jeremiah 31 and 2LCF 19. The sermon closes by tracing the law's three uses — civil, pedagogical, and normative — so that hearers neither abuse the law as a ladder to heaven nor discard it as obsolete, but receive it as the Spirit-given pattern for a life of grateful obedience.
1 Samuel 15:10-23
Saul's partial obedience to God's command to destroy the Amalekites exposes the anatomy of hypocritical religion: self-congratulation in the face of clear disobedience, blame-shifting, and the use of pious pretexts to cover rebellion. Working through 1 Samuel 15:10–23, the study examines how Samuel's confrontation strips away each layer of Saul's self-justification and arrives at the declaration that to obey is better than sacrifice. The text drives home that partial obedience is not obedience, that rebellion against God's word carries the gravity of witchcraft and idolatry, and that the only honest response is open confession and reliance on the perfect obedience of Christ in the sinner's place.
The Pattern for Gospel Ministry
Second Timothy 1:8 calls Timothy — and by extension all ministers and believers — to an unashamed allegiance to the gospel of the Lord Jesus Christ and a readiness to suffer for it. The sermon traces two movements in the verse: a prohibition against shame and a positive exhortation to share in the sufferings of the gospel according to the power of God. Four temptations toward shame are examined — the person of Christ, the work of Christ, the doctrine of Christ, and the cause of Christ — before the message closes with the assurance that the Spirit supplies power, not fear, to those who must persevere under opposition and trial.
The Instruction Concerning Defilement
True defilement, according to Jesus in Matthew 15:10–20, does not originate in ceremonially unwashed hands but in the corrupt human heart. This sermon works through the confrontation between Christ and the Pharisees to show that external religious observance — however scrupulous — cannot address the root problem of moral and spiritual depravity. The text exposes the wretchedness of fallen human nature through the catalog of sins Jesus names in verses 18–19, and drives the hearer to recognize that only the atoning work of Christ — his perfect obedience, substitutionary death, and resurrection — provides the remedy an unwashed heart requires.
The Gospel's Prophetic Prologue
Mark 1:1–4 introduces the gospel not as a literary convention but as the announcement of a real, historical event: the life, death, and resurrection of Jesus Christ, the Son of God. This passage establishes that the gospel's ministerial beginning is rooted in prophetic fulfillment, as both Malachi 3 and Isaiah 40 foresaw a wilderness messenger who would prepare the way of Yahweh himself. The identity of Jesus as the divine Son of God is not incidental to the gospel but is its very foundation — without his deity, there is no sufficient Redeemer. The sermon closes with a call for believers to know and proclaim the gospel precisely, to walk in a manner worthy of it, and for unbelievers to turn from sin and believe on Christ alone.
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.
Christ Our Peace
Ephesians 2:11–22 sets the Gentiles' former condition — Christless, hopeless, and without God — against their present status as full members of the one new covenant community purchased by Christ's blood. The sermon argues that Christ himself is peace, that he makes peace by abolishing the ceremonial law and reconciling Jew and Gentile to God through the cross, and that he preaches peace through the proclamation of the gospel. Gentile believers are now fellow citizens with the saints and members of the household of God, being built together as a dwelling place of the Spirit, and this corporate solidarity must be prized alongside the individual salvation it encompasses.
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 18
Deuteronomy 18 addresses two offices of spiritual leadership in Israel — the priests and the prophets — and sets them against the backdrop of the occultic practices of the Canaanites. The provision for Levites and priests (vv. 1–8) establishes that God, through the faithfulness of his covenant people, is the material sustainer of those devoted to sacred service. The prohibition against divination, sorcery, and necromancy (vv. 9–14) makes plain that Israel was to seek God's word through appointed means, not pagan dark arts. The chapter reaches its pinnacle in the promise of a prophet like Moses (vv. 15–22), which finds its ultimate antitype in the Lord Jesus Christ as prophet to the church.
The Parent/Child Relationship
Colossians 3:20–21 addresses both children and fathers as morally responsible members of the household of faith, calling each to a distinct duty within the domestic sphere. Children are commanded to obey their parents in all things — a command grounded in the moral law written at creation, codified in the Fifth Commandment, and motivated by the pleasure of Christ. Fathers are warned against provoking their children to discouragement, and are exhorted positively — drawing on Ephesians 6:4 — to nourish, instruct, and discipline with love, consistency, and dependence upon God. The sermon presses both charges as inseparable from the new life described throughout Colossians 3: orthodoxy must issue in orthopraxy, beginning in the home.
Deuteronomy 14
Deuteronomy 14 calls Israel to a holiness that pervades every dimension of life — how they grieve, what they eat, and how they handle their increase. The chapter's unifying principle is covenant faithfulness expressed through visible distinctiveness from the surrounding Canaanite peoples: to mourn, eat, or tithe like the pagans was to open the door to worshipping their gods. The dietary laws are treated not primarily as hygiene codes but as daily, embodied reminders of Israel's chosen status before God, while the tithing legislation frames giving not as burden but as festive, God-fearing rejoicing and provision for the community's most vulnerable.
The Law of Love
Matthew 5:43–48 contains the sixth and final antithesis of the Sermon on the Mount, in which Christ corrects the Pharisaic addition 'hate your enemy' — a phrase found nowhere in Scripture — and restores the full demand of the moral law: love your enemies, bless those who curse you, do good to those who hate you, and pray for those who persecute you. Christ is not introducing new legislation but faithfully expounding the eternal righteousness of the Father, whose law always required love even toward enemies, as texts from Exodus, Leviticus, Proverbs, and Job demonstrate. The sermon traces the contrast between true law and scribal distortion, the three positive duties of love, the theological ground of sonship in reflecting the Father's common grace, and the summary call to perfection — which ultimately drives the believer to the cross and to the imputed righteousness of Christ who alone satisfied these demands perfectly. Kingdom citizens are not bare-minimum disciples but are called, by the Spirit's enabling, to embody an ethic that distinguishes them entirely from tax collectors and pagans.
A Real Savior for Real Sinners
What does it mean that 'such were some of you' — fornicators, idolaters, adulterers, thieves, drunkards, revilers? Expounding 1 Corinthians 6:9–11, this sermon makes six observations: the kingdom of God is real; self-deception about one's standing before God is pervasive; God has established an objective ethical standard in his moral law; all men without exception stand guilty before that standard; sin is not genetic and therefore not beyond redemption; and Christ is a real Savior who truly washes, sanctifies, and justifies real sinners. The closing application calls believers to live a cross-centered life, letting the memory of what they once were fuel ongoing worship and praise.
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.
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.
A Biblical View of Homosexuality
Scripture condemns homosexuality not as a cultural accident or genetic condition but as a transgression of God's creational order, a sin judged in Sodom, legislated against in the Old Covenant, and confirmed in the New Testament. This sermon works through four biblical categories — creation, Sodom and Gomorrah, Mosaic legislation, and New Covenant confirmation — to establish that homosexuality is a moral offense against the triune God, not merely a violation of Jewish or sectarian code. The consistent refrain of Scripture is that this sin, like all sins catalogued in 1 Corinthians 6, is answered by a real Savior who washes, sanctifies, and justifies sinners — making a properly biblical view of homosexuality the only view that can offer genuine hope to those in bondage to it.
