How do we know that Jesus is the fulfillment of the promises made to David?

The promises made to David are inherently linked to the messianic expectations outlined throughout Scripture. In particular, God’s covenant with David ensures that his lineage would endure, ultimately culminating in Christ, who is referred to as the true David. This is articulated in passages such as 2 Samuel 7:12-16, where God assures David that his throne would be established forever. In the New Testament, these promises are affirmed through the genealogies presented in Matthew and Luke, which trace Jesus’ lineage back to David.

Furthermore, Jesus directly fulfills the prophetic expectations of David's greater son, evidenced by His miraculous works, teachings, and ultimately, His resurrection. Through His ministry, Jesus establishes an eternal kingdom, as foretold. This kingdom is not just limited to Israel but extends to all nations, illustrating the global scope of redemption promised to David. Thus, believing in Jesus as the fulfillment showcases the coherence of God's redemptive plan through history, reflecting the assurance that unlike David's earthly reign, Christ's kingdom will never end.
