The first sacrifice for mankind was an animal in the garden to provide clothing for him. Adam and Eve would see death as a result of their new condition of survival, the animals would be sacrifice as food, as clothing, their life would be intertwined with death, nothing would be able to escape the death sentence. Most heart piercing would be the violent, senseless death, mankind killing each other. Death as a consequence of sin would put an end to the natural elements but would be unable to penetrate the supernatural elements of being created in the image and likeness of God. Mankind would live without the natural until restored by God in the new Eden he will proclaim over this earth. The animals we have hope God will restore for their uniqueness and personalities in his ability to bring forth life out of stones should he choose to, nothing would be impossible for him. Death and sin will be hurled into the abyss, a far greater warning and punishment for those who would choose to continue with the serpent in disobedience. We all experience the first death, we will not all experience the second death, complete detachment from God, from life, from love, from good, from creation. God has clothed us in our nakeness and it was a sacrifice, God has restored us in his Son and it was a sacrifice, we caused the sacrifice, the least we should do is add our sacrifice to that of God's. We learn from God and we live with God, a way of life now and forever.
