Terry, you are wrong in several ways that come readily to mind. First, you'd have to be God yourself in order to negate what God says is Just, him being the ultimate standard of JUSTICE.
Yes, but, why establish your STANDARD...enforce that standard without exception and then, suddenly, throw up your hands and say: "Only kidding!"
Second, the payment model for crimes isn't unheard of in our justice system. Your own mother tried to take your punishment for you when you went to prison for not accepting alternate military service. This is a characteristic of a loving parent, which God is and without doubt you mom was as well.
Comparing human justic to Perfect Divine justice doesn't wash. My mother thought it was UNjust for a devout religious boy (I was 20) to go to prison. Her offer was a response to the INJUSTICE. Presumably, Jehovah did not suddenly view HIS OWN justice as UNjust?
Thirdly, the terms of the New Testament Contract require the DEATH of BOTH PARTIES.
Silly and wrong-headed! DEATH cancels all contracts. All values begin and end with LIFE not death.
Believers seal their end of the bargain when they die to themselves, give up their rights to themselves and sincerely can pray to God, "Do with me as you wish". When they FINALLY experience the separation of the soul from the body, they do indeed die. I have explained this to you over and over, yet you continue mischaracterizations of the Atonement.
Platonic greek "soul" mythology crept in to Judaism and tainted their soul-is-body theology. Jews believed life is precious because it ends. World Repair is the object of our lives. Just because you repeat your assertions does not make them any more credible.
The substitutionary atonement is not a free for all. It is very costly. It is a blood covenant to the death. It is designed so that "whosoever" can avoid JUDGMENT not the penalty for sin. Get it?
When you go to court and pay a fine instead of jail time either/both ARE a JUDGEMENT. You avoid nothing. The way the law is written determines the alternatives. In Jehovah's law given to Israel the penalty for sin is death. Where is the "substitute a perfect man and you get off free" clause???
Each human since Adam has created their own SIN DEBT. Jews had rituals of atonement from year to year. Gentiles did what was right in their own eyes.
No offer of life EVERLASTING had ever been extended to humanity since Eden as part of a JUST LAW. Blessings were for future generations of descendants, not the principle founder of a family line.
