2)What did this blood pay for?
It looks like I was replaced and even bartered for. His life for my life. Makes me think of slavery. We were in the garden of Eden, we broke the law and lost dominion over this planet. It would seem that Adam and Eve were under the jurisdiction of the new ruler of this world. We seem to be in double trouble. Left alone we are slaves to the devil who wants our homage and zero access to the tree of life so death looks to be an inevitability. Because we are all related to Adam, we all bear his death marked, Satan bondaged existence. The verse says that we are REDEEMED. Who set the price tag to be blood? God or Satan? Did Jesus redeem us from the Devils Dominion or death?
1) Why blood as a payment method?
We have all owed someone at one time or another. The cost is usually equivalent to the value of the item exchanged. We joke about something costing an arm or a leg. It's all fun and games until the price tag says O+. When does it ever really come down to that though? I have heard of people selling organs. I have even heard of the mafia killing someone because they were not able to cover the cost monetarily so it was taken out of them quite literally. The two methods aforementioned are usually done out of profit-making or vengeance. Why does God require blood to pay for something I did wrong. Is that an equal exchange? Is what I did so heinous? I can't imagine God's reason to be anything remotely close to our reasons for requiring blood. God does exhibit emotional expression, and some would probably say that his thirst for blood is accurate based on some of the seemingly harsh or judgments he is made in the Old Testament.
