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.
Judges 11:1-28
Judges 11:1–28 presents Jephthah as an unlikely deliverer — a man born of a harlot, expelled from his father's house by his half-brothers, who nonetheless rises to lead Israel against Ammonite aggression. The passage is read in two parts: first, the character and commissioning of Jephthah as a figure who typifies Christ in rejection and subsequent exaltation; second, Jephthah's remarkable diplomatic appeal to the king of Ammon, in which he dismantles the Ammonite territorial claim through history, theology, and legal precedent. The session closes with the observation that Israel's pattern of approaching God only in distress — mirrored in Gilead's approach to Jephthah — is a warning against a manipulative, technique-driven relationship with God, calling hearers instead to faithful, consistent submission to His lordship.
Capital Punishment, Part 2
Capital punishment is examined through Scripture, addressing both biblical and pragmatic objections to the state's God-ordained authority to execute criminal offenders. Drawing on Genesis 9:6, Romans 13:1–4, and several New Testament texts, the study demonstrates that the sixth commandment prohibits murder — not all killing — and that covenant theology maintains continuity between the Testaments on this point. Matthew 5:38–42 and John 8 are answered in turn, showing that neither the call to personal forbearance nor Christ's compassion toward the adulterous woman overturns the civil magistrate's duty to execute justice. Christians are called to govern their interpersonal relationships by a spirit of longsuffering while trusting God-appointed authorities to bear the sword faithfully.
Exclusive Commitment to God
Joshua 24 presents a covenant ratification ceremony at Shechem in which Joshua calls Israel to exclusive, whole-soul commitment to Yahweh on the basis of what God has done — not what Israel has merited. The sermon works through the chapter in two movements: a review of covenant history that highlights the grace, pace, ways, and power of God, and the demand for covenant commitment that is at once logical, exclusive, and serious. The sobering counter-intuitive move of Joshua — telling an eager people 'you cannot serve the Lord' — exposes the blathering self-confidence of emotional religion and drives the hearer back to dependence on divine grace from first to last.
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.
