Why are the Passover and its sacrifice important for Christians?

In Exodus 34:25, God commands that the blood of the Passover lamb, which was a type of sacrifice, must not contain leaven, symbolizing purity and the singular sufficiency of Christ's sacrifice. This reflects the doctrine that Jesus, as our Passover, fulfills the sacrificial system by offering Himself completely, without any human works interfering in God's redemptive plan. The Passover signifies not only deliverance from physical bondage but also represents the spiritual salvation afforded through Christ’s atoning work. This sacrificial imagery highlights important themes of substitution and redemption central to Christian faith.
