Therefore, faith does not begin with Jesus or Paul, but with Abraham. At the foundation of the economy of salvation lies the grace of God. God called Abraham—a "nobody" who did not earn his status—out of obscurity. Abraham’s role was simply to trust, acknowledging and accepting God's blessing through a lifelong commitment of faith. Jesus demonstrated this same faithfulness as the Son of God, revealing God's righteousness to the world (Romans 3:22) and fulfilling the Law and the Prophets rather than destroying them (Matt. 5:17).
Ultimately, the good news belongs to God. It is a single story of history that began with Abraham and finds its fulfillment in Christ (cf. Galatians 3). We must not overlook this vital continuity: the gospel is fundamentally the good news of God. In Galatians, Paul affirms that the root of the gospel lies in God's promise (Gal. 3:1–29).
