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

The New Testament reveals that Jesus Christ is the ultimate fulfillment of Old Testament types and shadows. For instance, in the events surrounding the Passover in Exodus, we see a foreshadowing of Christ's sacrificial death. The blood of the lamb applied to the doorposts signified protection and deliverance from death (Exodus 12:13), which is fulfilled in Christ's atoning sacrifice. He is the true Passover Lamb whose blood secures salvation for His people, illustrating that every aspect of the Exodus narrative prefigures His redemptive work.
