How do we know that Jesus fulfilled Old Testament prophecies?

The fulfillment of Old Testament prophecies by Jesus is evidenced through multiple New Testament affirmations where early Christians and Apostles explicitly connect Jesus' actions and experiences with specific prophecies. For instance, Paul declares in 1 Corinthians 15:3-4 that Christ died for our sins according to the Scriptures and was raised on the third day, which correlates with prophetic writings. Furthermore, Jesus Himself engages the Scriptures to demonstrate that His mission was rooted in their fulfillment, affirming their continuity and His role as the Messiah.
