How do we know that Jesus is our Passover Lamb?

In Christian theology, Jesus is referred to as the Passover Lamb because He fulfills the typology established in the Old Testament. Exodus 12 illustrates how the blood of a lamb protected the Israelites from judgment, serving as a foreshadowing of Christ's ultimate sacrifice. John the Baptist proclaimed, 'Behold the Lamb of God,' indicating that Jesus would be the sacrificial substitute for sinners. Through His death and resurrection, He not only delivers from physical death but secures eternal life for all who believe, as seen in Exodus 12:13 where God promises to pass over those covered by the blood.
