How do we know Christ is the fulfillment of the Passover?

In 1 Corinthians 5:7, Paul explicitly states that 'Christ, our Passover, has been sacrificed.' This connection emphasizes that Jesus embodies the true meaning of the Passover lamb. Just as the original lamb was to be without blemish, Jesus lived a sinless life, making Him the perfect sacrifice. The observance of the Passover foreshadowed His sacrificial death on the cross, where His blood was shed—not merely to cover sins temporarily, but to remove them entirely for those who believe. Thus, the type finds its fulfillment in the antitype, which is Christ Himself, rendering the need for the Passover obsolete in light of His completed work.
