Galatians 3:10-12 The Righteous Shall Live By Faith (January 11, 2025 AM, Dr. Michael Grasso)

In Galatians 3:10–12, the Apostle Paul brings his argument for justification by faith to a decisive conclusion. After appealing to the testimony of the Triune God (Christ crucified, the Father giving the Spirit, the Spirit working powerfully) and to the promises made to Abraham, Paul now shows why the law can never justify—because it can only pronounce a curse on sinners.

Paul’s reasoning is careful and often misunderstood. On the one hand, he decisively rejects legalism: any attempt to be justified by works of the law places a person under God’s curse, since the law demands nothing less than perfect obedience. Quoting Deuteronomy 27:26, Paul reminds us that failure at even one point brings condemnation. This leaves every sinner without hope if justification depends on law-keeping.

On the other hand, Paul is not promoting antinomianism. He is not denying the goodness of God’s law or the necessity of obedience in the Christian life. Rather, he is distinguishing between the ground of justification and the fruit of justification. Obedience does not earn righteousness, but true righteousness by faith always produces obedience.

To establish this, Paul appeals to Habakkuk 2:4: “The righteous shall live by faith.” In its original context, this declaration came in the face of impending judgment. Those who would survive God’s wrath would do so not by flawless obedience, but by trusting in the Lord and His provision of atonement. Paul rightly draws out the abiding principle: escape from judgment—both temporal and final—comes only through faith.

Paul then contrasts two fundamentally opposed systems: justification by works and justification by faith. The first rests on human effort and ends in curse; the second rests on Christ’s righteousness and ends in life. When Paul says, “the law is not of faith,” he is not rejecting Moses or the Mosaic covenant as legalistic. Instead, he insists that Moses himself taught that perfect obedience is required by the law—and therefore that sinners must seek salvation outside themselves, in God’s promised Redeemer.

The result is a unified biblical message: Moses and Paul agree. Scripture from beginning to end teaches that justification is by grace through faith alone, and that obedience flows from a heart transformed by that grace.

This passage confronts every hearer with a searching question:

Will you stand before God on the basis of your own obedience—or will you take refuge in Christ alone? The righteous, Paul declares, shall live by faith.
