The story in the Old Testament of the Passover lamb as the Hebrews fled Egypt links to Jesus, our Passover Lamb in the New Testament. As the Hebrews were saved by the blood of the lamb, so we are saved by the blood of Jesus, who sacrificed Himself for us on the Cross that we might be redeemed. All we have to do to gain that salvation is to feed on Christ in our hearts and absorb Him into our body by faith.
