Galatians 2:15-16 Justification by Faith (Part 3): OT Witness (November 16, 2025 AM, Dr. Michael Grasso)

"Is justification by faith really taught throughout the whole Bible—or is it just a “Pauline doctrine”? In Galatians 2:15–16, Paul insists that “we who are Jews know that a person is not justified by works of the law but through faith in Jesus Christ.” Why does he assume that every faithful Jew already knew this truth? Because the Old Testament itself proclaimed it.

In this sermon, we explore the historical witness to justification by faith:

Why justification by faith is the only way God’s justice can be upheld

How Psalm 143:2 shows that no one can be justified by works before God

Why the sacrificial system and atonement point to salvation by grace, not merit

How Abraham, David, Habakkuk, and the Prophets all taught justification by faith

Why Christ himself is called “The Lord our Righteousness” (Jer. 23:6)

From Genesis to the Prophets, from the Psalms to the Gospel, the entire Bible proclaims the same message: no one can be declared righteous by works of the law. Our only hope is Christ, whose perfect righteousness is freely imputed to us through faith alone.

This is the gospel Paul defended with all his strength—the same gospel proclaimed by Moses, David, Isaiah, Jeremiah, and fulfilled in Christ.
