Laws Concerning Homicide and Witnesses
Deuteronomy 19 applies three commandments of the Decalogue to the concrete conditions of civil life in Old Covenant Israel: the sixth commandment through legislation on cities of refuge distinguishing accidental homicide from murder, the eighth commandment through the prohibition on moving property landmarks, and the ninth commandment through the law of witnesses and its penalties for perjury. The sermon examines the distinction between manslaughter and premeditated murder, the role of the avenger of blood, the lex talionis as a limiting and proportional principle, and the blood-guiltiness that falls on a nation that fails to execute justice. The overarching application is that these laws reveal the sanctity of human life, the justice of God in civil society, and the sinfulness that made such detailed legislation necessary — all of which drives the hearer to the new covenant, in which Christ alone kept what Israel could not.
2LCF Chapter 23 - Of Lawful Oaths and Vows
Lawful oaths and vows occupy a distinct place in Christian ethics, grounded in the third commandment's demand for reverence toward the divine name and the ninth commandment's prohibition of false witness. This confession-study exposition of 1689 LBCF Chapter 23 distinguishes oaths (horizontal promises between men, made before God as witness) from vows (vertical commitments made directly to God), explains why both the Quaker rejection and Catholic corruption of oaths are condemned, and works through five paragraphs covering definition, solemnity, carefulness, integrity, and the lawful use of vows. The governing application is that the integrity of speech in all of life — family, church, and civic — flows from a rightly ordered fear of the God in whose name oaths are taken.
The Ninth Commandment: Part 2
The Ninth Commandment forbids not only perjury in a criminal court but all forms of lying, backbiting, slander, and gossip — sins Paul identifies as grieving the Holy Spirit within the church. The positive duty of the commandment requires active preservation of a neighbor's good name, charitable restraint of the tongue, and a settled love of truth grounded in the nature of God himself, who is the Lord God of truth, in contrast to the devil, who is a liar from the beginning. The threefold use of the law applies directly: the civil use restrains society from complete moral collapse, the pedagogical use exposes the sinner's need for Christ, and the normative use directs the redeemed — justified freely by grace through faith — in godly conduct toward one another. Every idle word will be accounted for on the day of judgment, making disciplined speech not optional but integral to the Christian life.
2LCF Chapter 23 - Of Lawful Oaths and Vows
The lawful use of oaths and vows — their definition, sanctity, necessary care, and required clarity — is examined through 2LCF Chapter 23 against the backdrop of three historical abuses: Roman Catholic monastical vows, state imposition on conscience, and the Anabaptist and Quaker rejection of oaths altogether. The chapter is read in full and then expounded paragraph by paragraph, demonstrating from Deuteronomy, Matthew 5, Matthew 26, and Hebrews 6 that oaths are a legitimate element of religious worship reserved for matters of weight and moment, taken only in the name of God with holy fear and reverence. The session concludes by connecting the call to truthfulness with the person of Christ, who as the only one who ever spoke in perfect truth, stands as the substitute for those who break their word.
Love your neighbour
Leviticus 19:9–18 sets out the concrete shape of neighborly love within the covenant community of Israel — not as sentiment, but as law. Working through gleaning regulations, prohibitions against theft, lying, exploitation, and a corrupt judiciary, the passage demonstrates that to love one's neighbor is to refrain from every breach of the second table of the Decalogue. The sermon shows that Jesus in the Sermon on the Mount and Paul in Romans 13 do not improve upon Moses but confirm what the moral law of God has always demanded: that love is the fulfilment of the law, and hatred of a brother is always a sixth-commandment violation.
The Conduct of the New Man, Part 1
Ephesians 4:25–28 grounds the Christian's ethical conduct not in legal compulsion but in the indicative of redemption: the old man has been put off, the mind is being renewed, and the new man has been put on. This sermon works through three prohibited actions — lying, sinful anger, and theft — each examined under its corresponding commandment from the Decalogue (the Ninth, Sixth, and Eighth), with a prohibition, an exhortation, and a motivation for each. The ethical demands of the New Covenant are not a new law but the restoration of the creational law now internalized by the Spirit according to Jeremiah 31:31–34. The hearer is called to put off deceit, guard against nursed anger that gives opportunity to the devil, and replace theft with diligent labor aimed at charitable surplus.
The Things God Hates
Proverbs 6:16–19 presents a numerical list of seven things God hates and finds abominable — a proud look, a lying tongue, hands that shed innocent blood, a heart that devises wicked plans, feet swift in running to evil, a false witness who speaks lies, and one who sows discord among brethren. This sermon works through each item in canonical order, grounding the list in its immediate context (the portrait of the son of Belial in vv. 12–15) and in the broader testimony of Proverbs, the Psalms, and the New Testament. The abominable members (pride, lying, murder, the cunning heart, swift feet) and the abominable actions (perjury and discord) are each exposed and applied. The sermon concludes by urging hearers to pursue the opposites of each vice — humility, truth-telling, protection of innocent life, guarding the heart, swift pursuit of good, faithful witness, and peacemaking — and to rest in Christ, whose perfect obedience is the righteousness that covers remaining corruption in the believer.
The 9th Commandment, Part 2
James 1:26 places the ninth commandment's prohibition of false witness directly inside the local church: a professing believer who does not bridle his tongue deceives himself, and his religion is exposed as useless — the same Greek word applied to idolatry. The sermon surveys the tongue's destructive power across James 3–4, Matthew 12 and 15, and a wide range of Proverbs texts, arguing that sins of speech are systematically undertriaged in the church compared to sins of action. Ten practical helps are offered, grounded in the conviction that taming the tongue is a fruit of genuine saving faith and requires the enabling power of the Holy Spirit working through the ordinary means of grace.
Exodus 1
Exodus 1 traces the rapid shift from Israel's prosperity under Joseph to their brutal subjugation under a new Pharaoh who knew nothing of the covenant arrangement his predecessors had honored. The chapter moves in two broad movements: the origin of the oppression in the multiplication of Israel, which paradoxically fulfilled God's Abrahamic promise of seed and land, and the gravity of that oppression as Pharaoh escalated from forced labor to state-sponsored infanticide. The defiance of the Hebrew midwives Shiphrah and Puah, grounded in the fear of God rather than the fear of man, illustrates the Reformed conviction that civil obedience finds its limit where God's law begins. The sermon closes by drawing three contemporary applications: vigilance against the gradual escalation of tyranny, confidence in the sovereign providence of God who keeps his covenant promises even through suffering, and the call to Spirit-wrought courage that refuses to silently deny Christ.
The Importance of Keeping the Heart
Proverbs 4:23–27 commands God's people to keep their hearts with all diligence, because the heart is the source from which all conduct flows — mouth, eyes, and feet are merely its outlets. Drawing on the warnings of Jeremiah 17:9, the illustrations of Proverbs 7, and Christ's own teaching in Matthew 15, this exposition argues that total depravity makes diligent heart-keeping not optional but urgent. The sermon closes by pressing that this command can only be obeyed through constant dependence on God's Word and Spirit, and that apart from Christ we can do nothing.
2LCF Chapter 23 - Of Lawful Oaths and Vows
Lawful oaths and vows, treated in 1689 London Baptist Confession chapter 23, are grounded in the third and ninth commandments and constitute genuine acts of religious worship — invoking God's omniscience, omnipresence, and vindictive justice as witness and judge. The confession distinguishes oaths (promises made to men before God) from vows (promises directed to God himself), insisting both require solemn care and plain sincerity without equivocation or mental reservation. Against Anabaptist denial and Roman Catholic abuse, the sermon defends the legitimacy of lawful oaths in matters of weight and moment, refutes the reading of Matthew 5 as a suspension of oath-taking, and condemns popish monastical vows — perpetual celibacy, professed poverty, and regular obedience — as superstitious snares without scriptural warrant. Hearers are called to prize truth-telling as a reflection of the character of God and to take every solemn oath with a full awareness of its theological gravity.
2LCF Chapter 23 - Of Lawful Oaths and Vows
What makes an oath lawful, and what does the Bible say about vows? Working through Chapter 23 of the 1689 London Baptist Confession of Faith, this study distinguishes between oaths (solemn promises made before God to men) and vows (solemn promises made directly to God), and defends the lawfulness of both against the Anabaptist refusal to swear. The Confession's four characteristics of lawful oaths — their nature as acts of worship, their sanctity as sworn in God's name alone, their solemnity requiring due consideration of weightiness, and their sincerity requiring plain speech without equivocation — are traced through Scripture and illustrated with examples ranging from courtroom testimony to marriage vows. The study closes by warning against rashly multiplying vows and condemning the Roman Catholic tradition of monastic vows as superstitious snares that mistake asceticism for holiness.
1 Samuel 21:1-15
David's flight from Saul in 1 Samuel 21 traces a fugitive's desperate stops at Nob, Gath, the cave of Adullam, and Moab — each one a theater of divine providence operating through human weakness, foreign enemies, and ancient familial arrangements stretching back to Ruth. The narrative neither excuses David's deception nor leaves him without bread; God sustains his anointed man not because of David's faithfulness but because of Yahweh's grace, planned long beforehand. Christ, the greater David, stands behind every detail: he is the captain of the distressed, the indebted, and the discontented, and his people are called to see their own trials as the very means by which God conforms them to the image of his Son.
Deuteronomy 19
Deuteronomy 19 addresses three domains of civil and judicial justice under the Mosaic law: the cities of refuge for accidental homicide, the prohibition against moving a neighbor's landmark, and the law governing witnesses and perjury. The cities of refuge reveal that God's law is concerned equally with punishing the guilty and protecting the judicially innocent — unexecuted murder and the execution of an innocent man both bring blood guilt upon the land. The law of witnesses, culminating in the lex talionis applied to the false witness, demonstrates that God does not take perjury lightly, and that biblical judicial procedure builds in structural safeguards against abuse.
The Third Commandment: Oath-Taking
Jesus' instruction in Matthew 5:33–37 is not a universal prohibition against oath-taking but a condemnation of the Pharisaic practice of swearing by created things — heaven, earth, Jerusalem, one's own head — as a device to lend apparent solemnity to speech while evading accountability to God. The sermon exposes this abuse by tracing the Old Testament's positive teaching on oaths, demonstrating from Christ's own submission to adjuration in Matthew 26 and from Paul's sworn affirmations that lawful oath-taking remains valid. The corrective Jesus offers is the kingdom ethic of simple truthfulness: the citizen of Christ's kingdom needs no oath to be believed, because his yes is yes and his no is no, and any compulsion to pad speech beyond this reveals the depraved bent traced ultimately to the father of lies. The Sermon on the Mount, rightly understood, drives the hearer to the cross, where Christ — who honored every commandment and swore to his own hurt — provides the righteousness no oath-keeper can supply for himself.
A Biblical View of Lying
The ninth commandment — 'You shall not bear false witness' — reaches far beyond the courtroom to govern every form of speech: perjury, slander, backbiting, gossip, tailbearing, and religious hypocrisy. The command is grounded in the character of God as the Lord of truth and in the practical necessity of social order, which collapses when confidence between persons is destroyed. The sermon closes by directing the hearer not to resolve moral reformation but to flee to Christ, whose sinless tongue and atoning death are the only ground on which the tongue-defiled sinner may stand.
