How do we know Christ is the true Passover lamb?

The Apostle Paul explicitly states in 1 Corinthians 5:7 that Christ is our Passover lamb who has been sacrificed. This revelation connects the Old Testament Passover lamb, which protected the Israelites from judgment, with Jesus’ sacrifice on the cross. The parallels draw a clear line from the blood marked on the doorposts during the Exodus to the sacrificial blood of Christ, signifying once and for all the completion of God's redemptive plan through Christ's atonement. Thus, it is through faith in Christ that we receive the benefits of this sacrifice and are saved from judgment.
