God’s pure nature requires perfect balance. Another way of saying balance is rest, justice, righteousness, a fulfilled purpose.
When we think or do things contrary to God’s perfect will, then we offset that perfect balance. To reset the scales of balance, we must submit an act of counter balance. That is what the Law is all about.
God was perfectly clear that if Man disobeyed, their life would be required. The Torah is perfectly clear that the life is in the blood. Before Man sinned, he was perfect. Afterwards, he was not. Therefore, a perfect man’s life Or blood could not be offered to counter balance the scales.
To start man’s path back to God, God gave them an object lesson to show them true Torah, True Balance. When man sinned, they attempted to cover their shame with natural things, God showed them that an innocent and perfect entity will need to be sacrificed for their shame to be covered.
Therefore, he gave them skins of an animal to show that innocent blood was required, to cover. That is what the Law is all about...to constantly remind mankind of God‘s perfection and that it is naturally unattainable.
