When God asked Abraham to sacrifice his only son, it was a test. This type of sacrifice was a common practice amongst the people (who worshipped idols) where Abraham had lived before God directed him to leave and seek the promised land, so he obviously did not see anything odd in doing this.
Abraham is known as the Father of Faith, so his assurance from God that he would become the father of a great nation was at the forefront of his mind as he climbed the mountain with his beloved son confident that God would not go back on His word.
And He didn’t.
Because Abraham was willing to sacrifice his son for love of Yahweh, at the same time knowing, by faith, that God was about to do something extraordinary, God was willing to sacrifice His Son for the redemption of mankind.
Fast forward to the first Passover.
“Judaism and Christianity are as inseparable as seed and flower or tree and fruit. In the light of the New Testament we obtain a full understanding of the Passover, while the deepest meaning of the Lord’s Supper cannot be fathomed without the historic background of the Jewish Passover.
Israel’s deliverance from Egypt is the central point in Jewish history and worship, even as Calvary is the central point in the Christian faith, for on Calvary the work of redemption was accomplished for every believer.
Passover, the story of deliverance, is the harbinger of a greater redemption yet to come, the vehicle of the undying Messianic hope. It was in the upper room (where Jesus and His disciples celebrated the Passover) that it at last obtained its real meaning and deepest significance”
(Excerpts from “The Gospel in the Feasts of Israel”, by Victor Buksbazen)
Blood sprinkled on the doorposts on the night of the first Passover to save them from the angel of death ~ Jesus’ blood shed for our deliverance from eternal death.
The Passover lamb slaughtered outside camp/city confines ~ Jesus crucified as the Lamb of God at a place called Golgotha, outside of the city of Jerusalem.
All the blood drained from the Passover lamb ~ All Jesus’ blood was shed, for when the soldier pierced His side only water flowed.
Not one bone of the Passover lamb was to be broken ~ Not one bone in Jesus’ body was broken.
There are so many things related to each event, referred to as Types in the Old Testament of things to come.
Finally another word from Mr Buksbazen ~
“Jesus Himself was the final reality of what the Passover lamb sought to convey originally. It is His blood that saves Jew and Gentile alike from the death of sin and eternal condemnation and makes the believer a child of God.”
You can read the account of the Passover in Exodus chapter 12 and the account of Jesus’ death in the Gospels of Matthew chapters 26,27,28 or Mark chapters 14,15,16 or Luke chapters 22,23,24 or John chapters 13-21.
