Deuteronomy 5:17 - 6th Commandment Part 4
Deuteronomy 5:17 forbids murder, not all killing, and the Westminster Larger Catechism identifies three exceptions: public justice, lawful war, and necessary defense. This sermon, the fourth in a series on the sixth commandment, examines the scriptural warrant for lawful war, moving from Old Testament legislation governing warfare and holy war through New Testament evidence of a consistently favorable view of the military. The argument concludes that Romans 13 authorizes civil government to wield the sword against both criminal offenders and foreign invaders, that this function is wholly consistent with the personal ethic of Matthew 5 and Romans 12, and that criteria derived from Augustine, Aquinas, and Turretin provide a biblical framework for distinguishing just from unjust war.
A Defense of Self-Defense
Matthew 5:38–42, the fourth antithesis of the Sermon on the Mount, is frequently invoked to condemn self-defense, capital punishment, and military service — yet a careful reading reveals that Jesus is not contradicting the lex talionis of the Mosaic civil code but rather correcting the Pharisaic habit of applying that courtroom principle to personal, day-to-day relationships. The contrast is not Jesus versus Moses but Jesus versus bad hermeneutics: what the civil magistrate is authorized to do with the sword (Romans 13:1–4) stands entirely intact, and Exodus 22:2–3's legitimization of self-defense is nowhere repealed. The sermon works through Jesus' four illustrations — insult, property disputes, conscription, and benevolence — to show that Christ is calling his disciples to a disposition of patience and forbearance in ordinary life, not to a pacifism that would render them incapable of functioning in civil society.
The 6th Command, Part 2
The sixth commandment's prohibition against murder extends far beyond the physical act of killing to encompass the internal disposition of the heart — unwarranted anger, bitterness, and character assassination. Drawing from Exodus 20:13, Matthew 5:21-26, Leviticus 19:17-18, and the Westminster Larger Catechism, this study traces the biblical distinctions between murder and lawful homicide (capital punishment, just war, and self-defense), demonstrates that all human beings at every stage of life bear the image of God and therefore possess inviolable dignity, and applies the commandment's positive duty to preserve life. Hearers are called to deal faithfully with relational sin rather than harbor grudges, to resist the culture of abortion and euthanasia as violations of the image of God, and to understand the civil use, pedagogical use, and normative use of this commandment.
The 6th Commandment
Exodus 20:13 — 'You shall not murder' — is one of the briefest commands in the Decalogue, yet it carries profound theological and legal weight. This expository Bible study examines the precise Hebrew terminology that distinguishes murder from other forms of killing, establishes the internal disposition (hatred, unrighteous anger, character assassination) as equally condemned by the sixth commandment alongside the external act, and then surveys three exceptions to the prohibition: capital punishment, just war, and self-defense. Each exception is grounded in both Old and New Testament texts, with sustained attention to the Noahic Covenant, Romans 13, and Exodus 22, demonstrating that the civil magistrate's sword is a God-ordained instrument of justice rather than a violation of the commandment.
The Wisdom of Little Things
Proverbs 30:24–28 presents four creatures — ants, conies, locusts, and a spider or lizard — each marked by inherent weakness yet possessing a compensatory wisdom that enables them to thrive. Expounding Agur's numerical proverb, this sermon draws out four corresponding virtues for the people of God: industry in preparation, caution before danger, unity in cooperation, and persistence under adversity. Both temporal and spiritual dimensions of each lesson are developed — from Sabbatarian labor ethics and self-defense to readiness for the day of judgment and the endurance of the Christian race. The whole is gathered under a call to honest self-awareness: to know one's limitations, refuse indolence and complaint, and by grace overcome through wisdom.
The Sixth Commandment
The sixth commandment, 'You shall not murder,' forbids not only the external act of taking innocent life but also the internal dispositions of hatred, unwarranted anger, and character assassination that flow from the same malicious heart. The sermon distinguishes murder from three lawful forms of killing — capital punishment, just war, and self-defense — grounding each in the abiding authority of Scripture from the Noahic Covenant through the New Testament. The image of God in every human being is the theological foundation for the commandment's reach across abortion, euthanasia, and the neglect of capital punishment. Hearers are called to clarity on the law's three uses, to renounce internal murder within the church, and to find in the gospel the only remedy for sinners who have violated this commandment in heart or deed.
The Sixth Commandment
The sixth commandment, 'You shall not murder' (Deuteronomy 5:17), rests upon the foundation of the imago Dei — the conviction that every human being, from the pre-born to the elderly, bears the image of the Creator, and that to assault an image-bearer is to assault God himself. The sermon distinguishes murder from lawful killing, arguing from Genesis 9, Exodus 22, and Romans 13 that capital punishment, self-defense, and just war are not violations of the commandment but are grounded in the same principle that makes murder heinous: the sanctity of human life. Modern applications — abortion, euthanasia, and the neglect of capital punishment — are examined in light of both Old and New Testament texts, and the sermon closes by directing those who have participated in these sins to the pardoning grace of Christ.
2 Samuel 13:23-39
2 Samuel 13:23–39 narrates the premeditated murder of Amnon by Absalom, the flight of Absalom to Geshur, and David's paralysis as father and king. The passage exposes how unaddressed sin compounds — David's failure to punish Amnon's rape of Tamar creates the conditions for Absalom's vigilante vengeance, fulfilling Nathan's prophetic word that the sword would not depart from David's house. Absalom's two years of nursed hatred illustrate Paul's warning in Ephesians 4 that unresolved anger gives place to the devil, and the passage ends by pointing the faithful forward to the promised Messiah, the son of David who will reign with the righteousness and justice no merely human king can sustain.
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 Death Penalty
Romans 13:1–4 grounds the civil magistrate's authority to execute criminal offenders not in political theory but in the creational ordinance of Genesis 9:6 and the delegated wrath of God. The sermon traces a biblical theology of capital punishment from the Noahic covenant through the Mosaic economy into the New Testament, demonstrating that the sword Paul assigns to the magistrate in Romans 13 is no metaphor but a mandate. Common objections — drawn from Exodus 20:13, Matthew 5:38–42, and John 8 — are answered exegetically, and pragmatic objections (racial disparity, deterrence, forgiveness) are answered from Scripture and reason. The hearer is called to submit to governing authorities as God's ordained ministers of justice, to renounce private vengeance, and — if an unbeliever — to flee to Christ before facing the ultimate Judge whose assessment of the heart no magistrate can anticipate.
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 Bible and Abortion, Part 2
Scripture consistently treats the unborn as image-bearers of God, and this sermon works through four questions designed to test that conviction: whether abortion is ever lawful, how to handle hard cases such as rape and incest, how to avoid abortion altogether, and what the church is called to do. Drawing on the biblical categories of lawful killing — self-defense, legitimate war, and capital punishment — the sermon demonstrates that abortion satisfies none of these conditions and therefore remains sin without exception. The hard cases do not alter the status of the conceived, and Deuteronomy 22 establishes that in rape the criminal, not the child, bears the penalty. The church's answer is the whole counsel of God: law that restrains sin and gospel that offers genuine hope to those who have already committed it.
