The promise of grace is affirmed through Scripture and the work of Christ, which assures believers of their salvation.
The assurance of the promise of grace is grounded in the historical and redemptive work of Christ as unfolded in Scripture. In Galatians, Paul clarifies that the law serves to lead us to Christ, and in Him, we find the fulfillment of God's promise. Luther emphasizes that the promise provides comfort in the conscience, which is vital for believers who often struggle with sin. Therefore, believers can trust in the promise of grace because it is anchored in God's unchanging character and the redemptive work of Jesus.
