The original Passover, people were saved who lived under the blood of an innocent sacrifice spilled on a wooden doorframe. Death passed over them and they were spared, able to escape their slavery and live in freedom. With Jesus, we find life by living under the blood of an innocent sacrifice spilled on a wooden cross. Death has passed over those who believe in faith, and we are free from the slavery of sin, and can live in freedom.
The original Passover was a miraculous and gracious act of God for His chosen people. The Passover through Jesus was a miraculous and gracious act of God for any and all who believe by faith. The original Passover was precious moment in time for those who were present, while Passover of Jesus is a permanent offering for all who believe. Jesus was the fulfillment and perfection of all things!
