It's not a "strawman argument". Over and over again "God cannot justify the unjust" as a proof God had to punish the sins of the wicked in exclusion of the second part of the verse.
It seems to me that it is your view that has this problem not my view. For example, death, the white seat judgement throne and Gehenna are incontrovertible proofs that God's view of justice is inseparable from not only His Law but in satisfying the full demands of His Law against sinners for their sins through retributive justice.
So, with some sinners and their sins you must have the moral nature of God and His view of Justice expressed and satisfied inseparable from retributive justice. However,with other sinners and their sins you veiew would have the moral nature of God and His view of justice expressed and satisfied apart from retributive justice. So it is your view that divides God's moral nature and view of justice into two contradictory expressions with regard to justifying the unjust. My view is consistent, and makes God view of justice consistent with sinners and sin. A more fuller explanation is given below.
It is assumed God not justifying the wicked means the wicked must be punished rather than conversion.
Again, the disconnect and division with God's nature rests with your theory not mine. Your theory demands that God has two different kinds of moral nature with regard to defining and satisfying justice for the very same kind of sinners and sins.
Let me explain. I hope you will agree that God's view of justice is based upon and determined by God's moral nature is it not? I hope you will agree that with all who remain unjustified before God that God's moral nature is expressed in a view and definition of justice that can only be satisfied by punitive retributive justice as evidenced by the Great White Seat Judgement and Gehenna. Hence, this view of justice must be consistent with God's moral nature or there would be no death, judgement day, and Gehenna. No rational Bible student can deny that self-evident truth as death, the Great White seat judgement and Gehenna are incontrovertible evidences of this view of justice.
However, it is your view of the atonement demands that God's moral nature and sense of justice can be fully satisfied with regard to the very same kind of sinners and sins BUT without that same moral nature based definition of justice administered to the non-elect. Hence, in the instance of some sinners and sins there is no satisfaction without retributive justice while in the instance of other sinners and sins there is satisfaction without retributive justice. So, in one instance the moral nature of God which defines his sense of justice cannot be satisfied against sinners and sins apart from retributive justice administered, while in another instance the moral nature of God which defines his sense of justice can be satisfied against sinners and sins without retributive justice.
Now, remember you have repeatedly stated that justification for sinners and sins under your system of the atonement is "apart from the law" which does demand retributive justice. Remember, also that it is the moral nature of God that defines God's view of justice. We know that God's view of justice is consistent with retributive justice and the Law of God but your system demands it is consistent with a view of justice that does not demand retributive justice for the very same kind of sinners and sins.
In direct contrast, my system is consistent throughout with sinners and sins in requiring retributive justice to satisfy the moral nature of God. I hope you can see why the conflict with God's nature rests in your camp not mine as you have two conflicting views of justice and yet we agree that it is the moral nature of God that defines God's view of justice.
I realize how you attempt to justify this contradiction of moral nature based justice systems. You use the terms "love" and "obedience" with regard to Christ as the basis for satisfaction. However, neither terms have any meaning apart from the law of God in its PRINCIPLE form and once that is understood your system simply falls apart.
This is why I said your view logically and Biblicly repudiates the cross of Christ.
