How do we know that Jesus is the fulfillment of the Old Testament?

Throughout Scripture, Jesus is presented as the fulfillment of the Old Testament promises and types. In Hebrews 1:2, we see that He is the heir of all things and the one through whom God made the worlds. Furthermore, every Old Testament prophecy regarding the coming Messiah points to Jesus's life, death, and resurrection. John 1:45 indicates that the apostles recognized Jesus as the one whom Moses and the Prophets spoke of. This fulfillment goes beyond mere prophecy; it encompasses the entirety of biblical typology, where events, characters, and institutions in the Old Testament prefigure and lead to Christ's redemptive work. This understanding solidifies the Christian faith as one rooted in the totality of God's revelation throughout history.
