How do we know that Jesus is the true Passover lamb?

The assertion that Jesus is the true Passover lamb is grounded in His characteristics and the redemptive work He accomplished on the cross. Like the Passover lamb described in Exodus 12, Jesus was without blemish and perfect, as noted in 1 Peter 2:22. Furthermore, Hebrews 9:12 states that by His own blood, He entered the holy place once for all, securing eternal redemption. Thus, the parallels between the sacrificial system established in the Old Testament and Jesus' sacrificial death confirm His role as the Passover lamb, who takes away the sin of the world.
