What if the entire Bible is telling one unified story through two intertwined threads—God’s plan for glory in Christ and His plan to redeem sinners? In this sermon from Isaiah 42, “Centuries of Witness,” we trace how God has progressively revealed His eternal counsel “bit by bit” across the Law, the Psalms, and the Prophets. We explore the “eternal purpose” thread—God’s plan to place all authority in heaven and earth under Jesus Christ—and the “redemptive” thread—God’s answer to sin and death through the promised Seed. From Genesis to the Davidic covenant, through the Psalms and key prophetic passages, we see how themes of kingdom, dominion, resurrection, and worldwide blessing increasingly converge on the person of Christ.

The message then walks through specific Old Testament prophecies that sharpen into remarkable detail: the virgin birth (Isaiah 7), the birthplace of the Messiah (Micah 5), His identity as God in the flesh and eternal King (Isaiah 9), and His atoning sufferings and substitutionary death (Isaiah 53). Along the way, we consider how these “former things” and “new things” validate God’s word, anticipate Christ’s cross and resurrection, and prepare for the final revelation of “the mystery” given to Paul. The sermon closes by urging us to read Scripture with this big-picture lens, to understand where we fit in God’s unfolding purpose, and to respond with the contrite, believing heart God looks for today.
