Paul's First Missionary Journey
Acts 13 records Paul's sermon in Pisidian Antioch, the first extended exposition of the gospel in the New Testament missionary narrative, and provides the historical backdrop for understanding why Paul wrote the epistle to the Galatians. Paul's address in the synagogue moves from Israel's redemptive history through the Davidic promise to its fulfillment in Christ's death and resurrection, culminating in a declaration that justification comes by faith alone, apart from the law of Moses — the very claim the Judaizers would later attack. The sermon also establishes that the local church, not para-church organizations or individual initiative, is the God-ordained sending structure for gospel missions, and that divine sovereignty in election (Acts 13:48) underlies every evangelistic endeavor.
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.
