It still doesn't make sense. We were talking about justice, and now you shift the goal posts and bring in sacrifice. How does the death of Jesus benefit mankind? All attempted explanations, like yours, rely on arguments that accept the concepts that you're trying to defend.
Those concepts come from the Bible. If you leave the Bible's explanation out of the equation, nothing makes sense.
It would be like trying to explain color to someone born blind.
Again, the arguments only make sense to those who are predisposed to accept them. What has the legal system of ancient Israel go to do with anyone else? Also, how do the laws of debt relate to "sin"? If I owe some-one money, obviously a benefactor can step in and pay my debt. But if I have committed a crime, then punishing some-one else is the antithesis of justice!
We can become debtors in many ways....not just with money.The Bible uses it because people understand that kind of debt.
I will give you an example of how a "debt" can be passed on to children without their consent and with no way to cancel it. Genetically inherited disease. Do children ask for these diseases to be passed down from an afflicted parent, like a bad debt? Do parents bring these children into the world knowing the risks, but hoping their children won't be too badly affected? Sometimes they do. At other times they will take the responsible step of remaining childless. Adoption isn't always an option when a parent knows that their condition is progressive and terminal. In the big scheme of things we are all dying anyway.....all suffering from the same terminal illness. No one wants to die....so if there was a cure for death, wouldn't we grab it?
When Adam and his wife withdrew from their Creator, they virtually unplugged themselves from his 'life support', thinking that they could breath quite well on their own....but their sin created a genetic mutation of some sort that was inheritable. It made them susceptible to all manner of physical breakdown, affecting every cell in their body. They had no control over this and neither did their offspring...it was a natural consequence of their own actions.....all of them inherited the same defect.
The Great Physician said that this genetic condition could only be remedied by someone donating their unique DNA, which would restore everyone to perfect health.....but in doing so they would forfeit their own life. That person volunteered willingly, even though the procedure would be painful. Would you not welcome the generosity and self-sacrifice of such a person, giving up their life to save everyone who lined up to accept their donation?
In all parts of creation we see equal opposites. They are a natural part of the way things are.
The Creator required an equal opposite to pay for what Adam denied his children. A perfect sinless life was lost...and a perfect sinless life had to be given, to balance the scales of justice.
There is no other way to describe what transpired. Israel's redemption laws explain it well.
If it makes no sense to you then it makes no sense......not much we can do about that. You cannot convince someone who isn't prepared to be convinced, nor can you "make a silk purse out of a sow's ear"...as the saying goes. To God's people, it all makes perfect sense because his spirit is what is opening up their understanding. Those "outside" will just never get it....no amount of explaining will do.
We tried......
