The framework which Yahweh provided for His offering to the world was provided through His self-giving to His “covenant” people Israel. As He brought them out of bondage in Egypt He instituted, through the Mosaic Covenant, the means by which humanity (and in particular, His “covenant people”) might have a relationship with Him. His holiness required that sinful people have their sin’s “covered” by the shedding of blood (for the “life is in the blood”). In His provision, and by way of foreshadowing His ultimate sacrifice (by offering Himself as the “Lamb of God who takes away the sins of the world” Jn. 1:29) He instituted the sacrificial system. The animal became the “substitution” for the Israelite people, it died instead of the people — that is if they were to have a “relationship” with their Holy God (without the shedding of blood there is no remission of sins). The following passage from Leviticus sets up how this framework of substitution worked: See Leviticus 16:4-11.
This kind of sacrificial practice was reinstated last passover by some ‘Orthodox Jews’ in Jerusalem. Here is a rather graphic video that shows what was commonplace and necessary for the Jews so long ago: Here it is .
It is unfortunate that many Jews have failed to recognize that Jesus is indeed our ‘Passover Lamb’:
7Cleanse out the old leaven that you may be a new lump, as you really are unleavened. For Christ, our Passover lamb, has been sacrificed. (I Corithians 5:7)
But what this video does illustrate is that sacrifice and substitution involves a very real and bloody thing. So often we Christians santize and domesticate the reality of what Jesus has done for us. We wear crosses around our necks, and make signs across our body (if we are of that kind of “tradition”). What Jesus did was and is intensley real, it recognizes humanities’ real problem (death); and does not try to gloss over the “rawness” of such existence. What Jesus did, as our sacrifice, penetrates deeper than ‘joints and marrow’; it delves into the depths of human rebellion by putting it to death. Unlike the blood of “bulls and goats,” what Jesus did is not “provisional” or “typical;” instead it is “ultimate” and “everlasting.” It deals with our real problem, not with our ‘outward behavior’ (which is just a symptom); but with the root issue, and that is our “self-love” and soloptic rebellion toward God!
