Galatians 3
Chapter overviewAI-generated
Overview. This chapter centers on the contrast between justification by faith and justification by the works of the law, urging the Galatians to remember that their reception of the Spirit and their standing before God came through faith, not law-keeping. Paul anchors his argument in the example of Abraham, the nature of God’s covenant promise, and the purpose of the law, showing that the law never annulled the promise but served a temporary, preparatory role until Christ came.
Flow.
- Paul begins with sharp pastoral concern, questioning how the Galatians received the Spirit—by law or by faith—and challenges their shift toward legalism.
- He appeals to Abraham’s example: righteousness came through faith, not law, making believers the true children of Abraham.
- Paul explains that the law, given later, cannot nullify God’s earlier promise; rather, its purpose was to expose sin and act as a guardian until Christ.
- The chapter culminates in the declaration that in Christ, all believers are united as one people of God, no longer under the law’s supervision, but heirs according to promise.
Connections. Following chapter 2, where Paul defends the gospel of grace and his own apostolic authority against judaizing influences, chapter 3 deepens the theological foundation of that gospel by rooting it in Scripture and the Abrahamic covenant. It prepares the way for chapter 4, which develops the metaphor of sonship and inheritance, showing how believers move from slavery under elemental principles to adoption as God’s children through Christ.
What it teaches. The chapter teaches that sinners are justified by faith alone, as demonstrated in Abraham’s belief being counted for righteousness (WCF 11.1, HC LD 7). The law, given 430 years after the promise, was not intended to replace or supplement faith as the means of salvation, but to reveal transgression and drive people to Christ (WCF 19.3, HC LD 19). Christ bore the curse of the law to redeem those under it, so that both Jews and Gentiles might receive the promised Spirit through faith (WCF 8.5, HC LD 15). The law’s temporary, tutelary role ends with the coming of faith in Christ, and all who belong to Him—regardless of ethnicity, status, or gender—are united as one and become heirs according to promise (WCF 26.1, HC LD 23).
Apply. Trusting in Christ alone unites us to Him, clothes us with His righteousness, and makes us part of the promised family of Abraham.
