How do we know Christ is the true sacrifice?

The depiction of Christ as the sacrificial Lamb correlates directly with the Passover lamb prescribed in the Old Testament, which had to be without blemish and slaughtered at a specific time. During the Last Supper, He identifies the bread as His body and the wine as His blood, illustrating His impending sacrifice. The nature of His death and the specific events surrounding it were not arbitrary; they were orchestrated to fulfill the divine purpose established before time. This legislation of sacrifices in the law points to the necessity of a perfect and ultimate sacrifice, which Christ embodies.
