The Characteristics of the New Man
Ephesians 4:17–24 sets before believers a stark contrast between the darkened, alienated mind of the spiritual Gentile and the renewed mind of the new man in Christ. The sermon argues that verses 22–24 are not imperatives commanding believers to transform themselves, but indicatives declaring what God has already accomplished in regeneration: the old man has been put off, the mind is being renewed, and the new man has been put on. These realities — rooted in the second Adam reversing what the first Adam forfeited — form the doctrinal foundation upon which the ethical commands of Ephesians 4:25–6:24 rest. Believers are therefore called to walk in a manner consistent with what they already are in Christ, using the ordained means of gospel preaching, Scripture, and prayer to pursue sanctification.
Exodus 10
Exodus 10 records the eighth plague of locusts and the ninth plague of darkness, both of which expose Pharaoh's hardened pride and vindicate the sovereignty of God over Egypt, its rulers, and its gods. The hardening of Pharaoh's heart is examined not as a capricious act but as a judicial act of divine justice against a man and a dynasty already guilty of enslaving and murdering God's people. The passage carries forward two covenantal purposes: the public declaration of God's supremacy and the transmission of that knowledge to successive generations within the covenant community. Believers are called to pray for God's glory above all earthly concerns, to refuse embarrassment over God's justice, and to trust his sovereignty even in prolonged seasons of affliction.
Bible Study - Exodus 4
Exodus 4 continues the call narrative begun in chapter 3, tracing Moses' repeated reluctance to accept the commission to deliver Israel from Egypt and God's patient, sovereign response to each objection. God confirms Moses' authority through three authenticating signs — the rod becoming a serpent, the leprous hand, and water turned to blood — not as ends in themselves but as instruments to authenticate Moses as God's spokesman, consistent with the function of signs throughout Scripture. The chapter's second half traces Moses' return to Egypt, including the judicial hardening of Pharaoh's heart as an act of divine justice rather than injustice, Israel's identification as God's firstborn, and the concluding scene of Israel's elders bowing in worship upon receiving Moses and Aaron's testimony. The sermon calls hearers to find comfort in the absolute sovereignty of God over nature, disease, human speech, and pagan rulers, and to let that knowledge shape reverent, joyful corporate and private worship.
The Christian Husband/Father
The duties of the Christian husband and father are examined through the book of Proverbs, with Proverbs 4:1–9 as the anchor text and wide-ranging support from Deuteronomy and the New Testament. The sermon sets forth the godly husband as one who fears the Lord, deals with sin, provides for his household, protects his wife, communicates faithfully, and maintains sexual purity. The Christian father is then treated under four heads — being a godly man, loving his children, instructing them in word and life, and disciplining them with both verbal correction and, when necessary, the rod — all exercised in love rather than anger or indulgence. The closing application calls fathers to confess sin before their households, pray for and preach law and gospel to their children, and rest not in their own performance but in the imputed righteousness of Christ.
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 Rejection of Heretics
Titus 3:9–15 closes Paul's letter to Titus with a sharp command to avoid unprofitable disputes and to reject the divisive man — a command the broader pastoral epistles and the apostolic witness consistently reinforce. The sermon distinguishes heresy from damnable heresy, identifying denial of the Trinity, the hypostatic union, and justification by faith alone as the errors that condemn, while pressing the church not to confuse the struggling saint with the proud, self-serving false teacher. Church discipline for doctrinal error is treated with the same gravity as discipline for moral sin, and the concluding emphasis on good works is grounded in the confession that such works are the fruits and evidences of a true and lively faith, not the grounds of justification.
Stephen's Defense, Part 6
Acts 7:37–43 records Stephen's appeal to the wilderness generation as the climax of his defense before the Sanhedrin, demonstrating that Israel's persistent idolatry — not Stephen's teaching — represents the true rejection of Moses and of God. Stephen cites Deuteronomy 18:15 to show that Moses himself predicted the coming of Christ, the prophet like Moses, so that the council's rejection of Jesus is simultaneously a rejection of Moses and of the living God who sent him. The sermon traces Israel's descent from refusing Moses' word, to fashioning the golden calf, to God judicially giving them over to worship the host of heaven, drawing a direct line from Exodus 32 through Amos 5 to the very council Stephen addresses. The practical summons is double: flee idolatry in all its forms, whether tangible or inward, and flee to the God who, even in righteous judgment, remains ready to pardon.
The First Petition of the Lord's Prayer
The first petition of the Lord's Prayer, 'Hallowed be Your name' (Matthew 6:9), confronts the creature's instinctive self-centeredness with the prior claim of God's glory. The sermon unfolds the meaning of God's name — his triune being, his attributes, and his word — before explaining that the petition does not pray God into holiness but calls the creature to recognize and reflect holiness that already belongs to God essentially. Five practical particulars for praying this petition are drawn out: knowing, professing, depending on, esteeming, and promoting the divine name — with the sobering insistence, drawn from John Owen, that he who prays as he ought will endeavor to live as he prays.
The World According to Haggai
Haggai 2:10–23 confronts a people whose neglect of God's house exposed a deeper failure: they had made comfort and self-interest primary while relegating God to an afterthought. The sermon traces two movements in the text — a promise of blessing conditioned on restored covenant faithfulness (vv. 10–19), and a messianic announcement centering on Zerubbabel as an ancestor of Christ (vv. 20–23). Defilement, unlike holiness, is contagious, and the unbuilt temple was not merely a construction failure but a declaration that God was an unwanted resident. The governing application, drawn from Matthew 6:33, is the imperative to seek first the kingdom of God and his righteousness in every domain of life — worship, work, evangelism, and devotion.
