The Creepers, The Contenders, and The Keeper
The epistle of Jude addresses a crisis in the early church: ungodly men have crept in unnoticed, turning the grace of God into a license for lewdness and denying the Lord Jesus Christ. This exposition works through Jude's single chapter under three headings — the creeping ones (false teachers characterized by sixfold ungodliness and certain condemnation), the contending ones (the called, sanctified, and preserved who are charged to earnestly defend the faith once for all delivered to the saints), and the one who keeps them (Jesus Christ as keeper, master, eschatological judge, and sender of apostolic messengers). The sermon presses the cessationist and confessional conviction that the canon is closed and the faith delivered once for all, and closes with a call for both unbelievers to flee to Christ and believers to hold fast to gospel doctrine with theological love rather than cold dogmatism.
Gospel Liberty and the Law of Love
Gospel liberty, rightly understood, is not freedom from responsibility but freedom for the service of God and neighbour. Expounding Galatians 5:13–15, this sermon argues that Paul is no antinomian: believers called to liberty are simultaneously called to fulfil the moral law through love, and the gospel of free justification is the very source of genuine sanctification, not its enemy. Four theological implications of Paul's appeal to Leviticus 19:18 are drawn out — Paul's rejection of antinomianism, the threefold distinction in the law, the continuity of the moral law from creation through Sinai into the new covenant, and the complementary rather than antithetical relationship of Spirit and law — before the sermon closes with a sober warning that biting and devouring within the church betrays a failure of gospel-wrought love. The congregation is exhorted to pursue loving service of one another as the God-appointed antidote to both legalism and licentiousness.
The Apostle's Paternal Appeal to the Galatians
Galatians 4:12–20 presents the Apostle Paul's most personal and emotionally charged appeal in the letter — not a doctrinal argument but a pastoral one, grounded in shared history and genuine affection. The sermon expounds two movements in the passage: a reminder of the filial relationship Paul shared with the Galatians on his first visit among them, and a warning against the Judaizers whose zealous courtship of the Galatians serves not the glory of Christ but the aggrandisement of themselves. Throughout, the preacher presses the point that sound doctrine and warm pastoral affection are inseparable — contending for justification by faith alone must be done with the heart of a nursing mother and a grieving father, not merely the pen of a polemicist.
The Example of Abraham
Galatians 3:6–9 presents Abraham as Paul's decisive scriptural witness against the Judaizing demand for circumcision alongside faith. Drawing from Genesis 15:6, Paul demonstrates that Abraham's justification was by faith alone — faith as the instrument, not the ground, by which righteousness was reckoned to his account — and that this same faith-righteousness is the only basis on which anyone, Jew or Gentile, stands as a son of Abraham. The sermon works through four theological implications: imputed righteousness comes through faith alone, sonship to Abraham belongs only to the believing, Scripture itself preached the gospel to Abraham in advance, and the blessing of God falls exclusively on those who share Abraham's faith. Hearers are called to rest in the peace, gratitude, and humility that flow from justification by grace alone through faith alone in Christ alone, and to guard against every system — ancient or modern — that supplements faith with human merit.
Faith, Hope, and Love
Hebrews 10:19–25 brings the great doctrinal section on Christ's high priestly office to its application: two encouragements and three exhortations that together constitute the whole of the Christian life. The believer's boldness to enter the holiest and the possession of a perfect High Priest over the house of God are not abstract truths but the very engine of sanctification — the gospel must be grasped before the commands can be obeyed. The three exhortations — draw near with full assurance of faith, hold fast the confession of hope without wavering, and consider one another to stir up love and good works — are expounded as the expression of faith, hope, and love respectively, against the persistent errors of emotionalism, legalism, and perpetual self-condemnation.
The Defense of Justification by Faith Alone
Galatians 2:17–21 presents one of Paul's sharpest defenses of justification by faith alone, and this exposition works through three movements in the text: the proper and improper uses of the law (vv. 17–19), the personal experience of crucifixion with Christ as the ground of the justified life (v. 20), and the exclusivity of grace that renders any supplementation of the gospel a nullification of Christ's death (v. 21). The sermon exposes the logic of the objection that justification by faith makes Christ a 'minister of sin,' refutes it from the text, and shows that legalism — not antinomianism — is the true transgression of God's law. The central application is that any 'Christ-plus' system, whether formal theology or informal churchly shibboleths, empties Calvary of its meaning and must be resisted.
The Apostle of Christian Liberty
Galatians 2:1–10 presents Paul defending the divine origin of his apostolic gospel against Judaizers who demanded circumcision as a condition of justification. Working through three considerations — Paul's second post-conversion visit to Jerusalem, the case of Titus, and the unity of the apostolic witness — the sermon argues that any addition to the finished work of Christ destroys the gospel rather than completing it. The contrast between Timothy's voluntary circumcision for missional expediency and Paul's refusal to circumcise Titus illustrates the line between cultural accommodation and doctrinal compromise. Hearers are pressed to stand firm against every modern form of the Galatian heresy and to rest their justification on Christ's doing and dying alone, received by faith alone.
Possession, Position, and Privileges of Believers, Part 1
Philippians 3:8–11 sets the apostle Paul's counting of all things as loss against the surpassing worth of knowing Christ Jesus as Lord, and this sermon expounds that text as a sustained defense of justification by faith alone. Working through Paul's commercial language of profit and loss, the preacher distinguishes between Paul's past renunciation of his religious pedigree and his present, continuous counting of all things as rubbish, pressing the congregation to feel the radical reorientation the gospel demands. The heart of the exposition is the doctrine of imputed righteousness in verse 9 — the forensic declaration by which God pardons sins and credits Christ's active and passive obedience to the believer — set in direct contrast with Rome's infusion of righteousness and with modern Protestant departures such as the New Perspective on Paul and the Federal Vision. Because justification is an objective, once-for-all act of God and not a process, assurance is grounded in Christ's faithfulness alone, not in the believer's covenant performance, freeing sanctification to flow from gratitude rather than fear.
The Description of the Heresy
Colossians 2:16–23 exposes a syncretistic heresy threatening the church at Colossae — a blend of Jewish legalism, pagan mysticism, and bodily asceticism — and Paul's response is to anchor the believer's complete standing in Christ alone. The sermon works through three facets of this false teaching: the imposition of dietary laws and calendar observances as religious requirements, the pursuit of angelic visions and experiential 'higher planes' above Scripture, and the self-imposed bodily regulations that, despite their appearance of wisdom, fuel rather than subdue the flesh. The governing principle throughout is that Christ plus anything — legalism, mysticism, or asceticism — is heresy; Christ plus nothing is the gospel.
The Best Defense
Colossians 2:8–10 issues a double-edged call: beware of the spiritual kidnapping of godless philosophy, and rest in the sufficiency of Christ in whom all the fullness of the Godhead dwells bodily. The sermon exposes the 'Christ plus' logic underlying ancient and modern heresy — circumcision, asceticism, angel-veneration, and their contemporary equivalents — as substitutes for what believers already possess completely in Christ. The best defense against false teaching is not vigilance alone but a thoroughly biblical Christology, grounded in the conviction that those who are in Christ are complete in the head of all principality and power.
Redemption Through the Curse Bearer
Galatians 3:10–14 presents two mutually exclusive grounds on which a sinner might attempt to stand before God: the works of the law, which place every performer under a divine curse, or faith in Christ, who became that curse in the place of his people. This sermon expounds the universal and just nature of the curse fallen humanity labors under, the identity and substitutionary work of the Redeemer who bore it, and the nature of redemption as a purchased liberation from condemnation. The parable of the prodigal son in Luke 15 is brought alongside Galatians 3 to press the willingness and joy of Christ in receiving sinners, calling every hearer to look to him in faith rather than to any measure of personal law-keeping.
Paul's Conflict and Concern for the Colossians
Colossians 2:1–5 exposes both the nature of Paul's apostolic struggle and the objectives that drove it: he agonized in prayer for churches he had never visited because the stakes of false teaching are eternal. The sermon traces four objectives of Paul's conflict — that believers be encouraged in heart, united in love, assured in understanding, and consumed with Christ as the sole treasury of wisdom and knowledge — before turning to Paul's concern in verses 4–5, where persuasive words are shown to be the perennial weapon of heresy. The antidote is not rhetorical sophistication but deep, corporate rootedness in the person and sufficiency of Christ, which alone guards the church against the humanistic philosophy, legalism, mysticism, asceticism, and antinomianism Paul will address throughout the epistle.
