From Persecutor to Preacher, Part 2
Paul's early Christian career in Galatians 1:15–24 demonstrates that his apostolic commission and gospel were received directly from God, not derived from or validated by any human authority. His separation from the womb, effectual calling by grace, and the revelation of Christ in him establish divine sovereignty over his entire ministry — from persecutor to preacher. The sermon engages the 'new perspective on Paul,' arguing that the Reformation reading rightly identifies individual sin and grace as the heart of Paul's theology, not merely the corporate sociological question of Jew-Gentile relations. The hearer is pressed to trust in Christ alone, whose blood atones for great and invincible sins, and to see every human supplement to that atonement as an assault upon the cross itself.
From Persecutor to Preacher
Paul's autobiography in Galatians 1:11–24 is not self-promotion but a defense of the divine origin of his gospel and apostolic authority. Working through Paul's former conduct as a practitioner, persecutor, and professor of Judaism, the sermon argues that no man so deeply invested in Judaism would have invented or received the gospel of free and sovereign grace from merely human sources — it came by direct revelation of Jesus Christ on the Damascus road. The conversion of Saul of Tarsus is thus a monument to sovereign, particular grace: God saved His chief enemy and commissioned him to preach the very gospel he had tried to destroy. The sermon calls the unconverted to see in Paul's transformation the sufficiency and willingness of Christ to save the most wretched sinners, and summons believers to tenacious defense of justification by faith alone.
Introduction to Galatians
Paul's letter to the Galatians stands as a polemic defence of justification by faith alone — a truth so foundational that its corruption, however subtle, constitutes the destruction of the gospel itself. This introductory exposition surveys the authorship, dating, and destination of the epistle, arguing for the South Galatian theory and an early date of AD 48–49, while tracing the theological threads that run through the letter: the integrity of the gospel, justification sola fide, the atoning work of Christ, and Paul's apostolic authority. The Judaizing error that provoked Paul's letter is shown to be perennially recurring — in Roman Catholic merit theology, in the New Perspective on Paul, in Federal Vision, and in the subtler forms of works-righteousness embedded in church culture. Hearers are called to rest their entire standing before God on the imputed righteousness of Christ received through faith alone, and to contend earnestly for that doctrine as Paul did.
Greetings and Final Instructions
Colossians 4:7–18 closes Paul's letter not with abstraction but with names — real men whose faithfulness, failure, restoration, and apostasy illuminate the pastoral realities of gospel ministry. The passage reveals Paul not as a theology machine but as a suffering apostle sustained by the fellowship of Jewish and Gentile brothers alike, directing the advance of Christ's kingdom from a Roman prison cell. The sermon draws from each figure a single defining lesson — faithfulness, restoration, saving grace, apostasy, and strategic kingdom labor — while closing with an exhortation to guard against heresy by making much of the supremacy of Christ.
