How do we know Jesus is the fulfillment of the promise to Judah?

The New Testament presents Jesus as the fulfillment of the promises made to Judah, particularly seen in Hebrews 7:14, which notes that our Lord sprang out of Judah. The lineage and the prophetic blessings spoken over Judah in Genesis 49 reflect the coming Messiah's authority and role as our Savior. Judah's prerogatives—as depicted through his victory over enemies—point to the ultimate victory of Christ over our spiritual adversaries, affirming the sovereign grace theology that asserts that salvation and deliverance come through Christ alone.
