The Transition from Darkness to Life, Part 2
Ephesians 5:8–14 calls blood-bought believers to walk as children of light because they have been transferred out of darkness, not merely instructed to avoid it. The sermon traces the Pauline pattern of indicative preceding imperative: the cross does not follow obedience as its reward but precedes and enables it as its ground. The fruit of the light — goodness, righteousness, and truth — is the positive obligation of the justified, while the unfruitful works of darkness are to be actively exposed through the proclamation of God's law and gospel, with the certain confidence that Christ himself guarantees the triumph of that light.
The Conduct of the New Man, Part 3
Ephesians 5:1–2 concludes Paul's extended exhortation on the conduct of the new man (Ephesians 4:17–5:2), calling believers to be imitators of God as dear children and to walk in love. The basis for this imitation is theological: God is definitionally love (1 John 4:8, 16), believers have been adopted into his family by sovereign election and effectual grace, and family membership carries both privilege and responsibility. The motivation for walking in love is the penal substitutionary atonement of Christ, whose self-offering was an acceptable sacrifice to the Father — the antitype of the Old Testament burnt offering — and whose love supplies both the standard and the ground for all Christian love toward God and neighbour.
The Conduct of the New Man, Part 2
Ephesians 4:29–32 calls believers to put off corrupt speech and bitter dispositions and to put on edifying words and a forgiving heart — not as conditions for salvation, but as conduct that flows necessarily from it. The sermon exposits the structure of Paul's exhortations: a prohibition, a positive exhortation, and a motivation in each subsection. Corrupt speech grieves the Holy Spirit, who has sealed believers for the day of redemption; and bitterness, wrath, clamor, and evil speaking are symptoms of the old man that must be mortified. The sermon closes with the ground of all Christian forgiveness: God in Christ has already forgiven us, and that forgiveness is the cause, not the goal, of our forgiveness toward others.
The Manifestation of God's Grace
Titus 2:11–15 presents God's grace not merely as the ground of salvation but as the very teacher of holy living. This exposition traces four aspects of grace in the passage: its appearance in the incarnation and atoning work of Christ, its instruction toward denial of ungodliness and worldly lusts and pursuit of sober, righteous, and godly life, its demonstration in the deity of the returning Christ and the definite redemption he accomplished, and its proclamation through authoritative gospel ministry. The controlling hermeneutical key is the grammatical and theological priority of the indicative over the imperative: believers obey not in order to be saved but because they have been saved, and inverting that order collapses the gospel into moralism.
Be Imitators of God
Ephesians 5:1–21 confronts believers with a single pressing question: what is truly honorable and acceptable in the sight of God rather than in the sight of men? Working through three consecutive imperatives — walk in love, walk in light, and walk in wisdom — the sermon grounds each in the indicative of redemption: because the Father has predestined, adopted, and redeemed a people through Christ's perfect and acceptable sacrifice, they must imitate God as dear children. The practical implications range from the mortification of sexual sin and covetousness to the filling of the Spirit expressed in mutual speech, psalmody, thanksgiving, and submission, all of which flow from what Christ alone accomplished as the only sweet-smelling offering acceptable to the Father.
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.
The Cost of Discipleship
Matthew 8:18–22 presents two case studies in discipleship: a scribe who too eagerly volunteers to follow Jesus without counting the cost, and a disciple who hesitates, asking to bury his father first. Working through the first case, this exposition presses the meaning of Christ's self-identification as the Son of Man — drawing on Isaiah 53 and Daniel 7 — to show that discipleship entails not earthly prosperity or ease but rejection, deprivation, and willing loss of temporal goods. The sermon closes by locating the ground of discipleship in the indicative of the gospel: God accepts sinners through Christ, and it is from that acceptance that the costly call to follow flows.
Beware of Forgetting God in the Land
Deuteronomy 8:6–20 presents Israel on the plains of Moab receiving Moses' final warning before entering Canaan: the land of promise will itself become the land of temptation. The abundance of water, food, and mineral wealth that God graciously provides carries within it the seed of self-sufficiency — the prideful declaration of verse 17, 'my power and the might of my hand have gained me this wealth.' The sermon traces the anatomy of spiritual forgetfulness, showing that disobedience is its inevitable symptom, idolatry its destination, and covenantal destruction its consequence. The appointed remedy is remembrance: to rehearse God's redemptive acts, receive his gifts with thanksgiving, and live by the indicative of grace as the foundation for all obedience.
The Command to Walk in Christ
Colossians 2:6–7 presents what Paul considers the heart and substance of the entire epistle: a command to walk in Christ, grounded entirely in the prior reception of Christ by faith. This sermon works through three particulars of that command — the indicative basis (what God has already accomplished in salvation), the imperative itself (walking in Him), and the attendant circumstances (being rooted, built up, established in the faith, and abounding in thanksgiving). The believer's walk is not a self-generated moral effort but a response to sovereign grace, sustained by the same divine power that accomplished the initial rooting in Christ.
From Alienation to Reconciliation
Colossians 1:21–23 sets before the reader a stark before-and-after portrait of what redemption accomplishes: sinners who were actively alienated from God and enemies in their minds, now reconciled through the physical death of Christ and destined to stand holy, blameless, and above reproach before the judgment seat. The passage distinguishes sharply between the reason for reconciliation and its purpose — God does not reconcile because we are holy, but in order to present us holy, grounding justification entirely in imputed righteousness rather than moral attainment. The sermon works through four movements in the text — the previous state of alienation, the present condition of reconciliation, the future destiny of vindication at judgment, and the present duty of grounded, steadfast perseverance in the faith — with the doctrine of the perseverance of the saints serving as the practical crown of the exposition.
