The penal substitution theory teaches that Jesus suffered the penalty for mankind's sins. Penal substitution derives from the idea that divine forgiveness must satisfy divine justice, that is, that God is not willing or able to simply forgive sin without first requiring a satisfaction for it.
Questions ... and pose some questions of your own as well.
It is said .... the wrath of God was poured out on Jesus who committed no sin ... who was completely innocent .... is that justice?
Was salvation made possible through justice or through Love?
As always please provide scripture.
It is part of the way "transactions" happen or occur in Heaven, that's why the sacrificial system in the OT, but when the one, the only one, came, who was the only one who possibly could, etc, ever could, etc, pay for "all", and "all of it all for all time", etc, then that one did it for us, and did so fully well willingly, etc...
But then even that one was pardoned or forgiven also, etc, shown by the proof of the resurrection, etc, all revealing God's very great and truly loving and forgiving nature before all, etc... But also His justice/judgement first also, but also how His great mercy, love, etc, ultimately triumphs over it all in the end...
That even the scapegoat was even Himself or itself spared or saved, etc...
The scapegoat itself is innocent, but is considered guilty, and is not normally spared or saved, but in this instance He/it was, etc, and God was trying to show us all something by "both", etc...
Which is/was or might have been something having to do with His great justice/judgement first, but also how His great mercy, love, etc, triumphs over it all in the end, etc...
Trying to show us something in "both", by both allowing it to die and/or perish, but and then also, in also sparing it or bringing it back, or back to life in or by the end, etc...
This that He is or was trying to show us by this, I probably don't have "all of all about it all" all figured out yet, etc... But I do know that He (God) is trying to show us something by "both", etc, in both allowing it to perish or die, but then also in bringing it back also, etc...
Maybe others have some thoughts maybe in just what all exactly God is or was trying to show us by all of this maybe, etc...?
God Bless!
