Galatians
A fierce defence of the gospel of grace, calling the church to live in the freedom secured by Christ alone.
About This Book
Galatians is written into a moment of gospel crisis. Churches founded through Paul’s preaching are being unsettled by teachers who insist that faith in Christ must be completed by obedience to the law. Paul writes urgently to defend the truth of the gospel and to protect believers from a message that would rob them of assurance, joy, and freedom.
The letter moves from Paul’s defence of his apostolic calling and gospel message (chs.1 to 2), through a tightly reasoned argument for justification by faith alone (chs.3 to 4), and into the lived implications of freedom in Christ (chs.5 to 6). The burden throughout is pastoral. Paul is not merely winning an argument but labouring to see Christ formed in his people, so that they live as free sons and daughters rather than fearful slaves.
Galatians trains the church to stand firm in the grace of God, refusing every rival gospel and living by faith in the Son of God.
Preach Galatians with clarity and courage. Keep the gospel stakes visible, resist softening Paul’s warnings, and show how grace alone produces both assurance and a transformed life.

- The cross, boasting is excluded except in the cross that creates a new creation.
Recommended Commentaries
Galatians rewards careful study because its argument is dense and its pastoral implications are profound. A clear primary commentary will help trace Paul’s reasoning, while a second voice can assist with the Old Testament background and theological connections.

Preaching and Teaching Helps
Galatians is short but demanding. Faithful preaching requires close attention to argument and careful pastoral application.
- Keep the gospel centre clear, repeatedly define what Paul means by faith, law, and grace.
- Trace the argument, avoid preaching isolated paragraphs without showing how they serve the whole letter.
- Handle warnings honestly, Paul’s strong language is meant to awaken, not to crush tender consciences.
- Explain Old Testament connections, Abraham, promise, and law are central to Paul’s case.
- Show the fruit of freedom, make clear how grace leads to Spirit shaped obedience, not moral drift.
This Book in the Story of Scripture
Galatians stands as a decisive witness to the gospel announced in the Gospels and proclaimed in Acts. It clarifies how the saving work of Christ fulfils God’s promises and establishes a people who belong to him by grace alone, apart from the works of the law.
The letter shapes assurance and holiness together. It forms believers who rest confidently in Christ’s finished work, walk by the Spirit in newness of life, and resist every attempt to ground their standing with God in performance rather than promise.
United to Christ by faith, the church lives in the freedom of grace, bearing the fruit of the Spirit as it awaits the fullness of the new creation.
