How do we know Christ is the fulfillment of Old Testament prophecies?

The New Testament treats Christ as the ultimate fulfillment of all Old Testament prophecies, including those spoken by David. The Scriptures establish that Christ is the 'rock' that David referred to in his last words, and His coming was foretold to bring light and salvation. Paul reinforces this in his teachings, highlighting that all covenants made with God's people ultimately point to Christ as the fulfillment of God's redemptive plan. The clarity with which Christ's life and mission align with Old Testament predictions offers profound assurance that He is indeed the promised Messiah.
