We know that a central part of the passover as instituted by God in Exodus 12 and 13 is the sacrifice of the passover lamb. We also know that Christ's death on the cross ended the sacrificial law because He became the passover lamb (1 Co 5:7), so that no further atonement can be made by sacrifice (Heb 6:6). Just like God led the Israelites out of Egypt, out of the house of bondage, Christ's sacrifice has led us out of bondage to sin, if we keep His commandments. So the divine work and ordinance has stayed the same.

But let us have a closer look at what a sacrifice was meant to be and meant to do for the people, in order to understand better what Christ did for us.

According to God's Law, a sin or a trespass offering was needed whenever atonement had to be made. Atonement is put together from the words "at" and "one", so it was meant to make one again with God the person or people who had sinned. The atonement sacrifice had to be unblemished, always. The sacrifice procedure was ritualistic, and usually the priests were the ones making atonement in the person's or people's stead. For the whole sacrificial law, including offerings that were not in connection with atonement, like burnt offerings or meat offerings, have a look at Leviticus 1-7. There are other sacrifices mentioned throughout the Law, but Leviticus 1-7 gives a good idea of what the principles behind sacrifices were. The Hebrews mostly offered animals, like the passover lamb, the blood of which was a token for the Israelites so that the angel of God would spare the firstborns of Israel (Exo 12:13), in short, the blood of the lamb saved their firstborns from death.

So the basic idea behind a sacrifice is the reconciliation between God and men, to restore the relationship between God and men. This is exactly what Christ's death and resurrection do for those that love God and keep His commandments. We are all sinners, the Law convicts us all (Rom 7:7-26), and so we all are in need of atonement to restore our relationship with God. Paul also explains that Jesus died for us when we were yet sinners, to reconcile us with God, and by rising from the dead to make salvation possible for us (Rom 5:8-11), like the blood of the passover lamb saved Israel's firstborns. This sacrifice on the cross was made once and for all, and cannot be repeated (Heb 9:24-28; 10:10).
