Exodus 29:14
"But the flesh of the bullock, and his skin, and his dung, shalt thou burn with fire without the camp: it is a sin offering."
I seriously doubt that we will ever understand the sacrifice Christ made to save us from our sins. When you look at the sacrifices God commanded the children of Israel to observe, you get a small picture of the sacrifice Christ made for mankind. The sacrifice that He made shows the great love that He has for every person.
