Our current culture is so rich that we live in a hyper-rich bubble unique to all of human history. We no longer suffer the great diseases and famines of the past. We travel vast distances and have cell phones that give us access to all human knowledge. But we lack the intimate knowledge of hardship and death that our ancestors saw in their villages and in Nature all around them. Safe within our bubble, we just don't understand Life in the raw, Life unfiltered. Evil causes death. It was a clear cause and effect relationship that our ancestors understood. Animal sacrifice was regarded as something that could reverse this inevitability. Perhaps the death of an animal would cover over human evil. Furthermore, those who sacrificed themselves could, in certain situations, protect the entire village. Though it's becoming harder for us hyper-rich people to see, the sacrifice of Christ is best viewed within this framework of our impoverished ancestors. It is the death of the obedient son to erase evil and grant life to others.
