Knowing that you must be supporting the false tradition of God imputing our sins to His Son on the cross, I have to question your use of imputed 'personal' sin.Furthermore, nobody here is claiming God imputed personal sin to Christ.
Is this another way of trying to separate God imputing His Son with sin, but not calling Him a sinner? He imputed 'our' personal sins to Jesus, but not any 'personal' sin of His own?
If so, then it still denies the truth of Scripture, that God Himself only imputes any sin, to the personal soul that sinned.
Eze 18:20
The soul that sinneth, it shall die.
Since God only imputes the personal sin of the person that sins, then if God imputes any sin to any person, then that person must be the one sinning; Else God is breaking His own word of promise and judgment, that only the soul that sins, it shall be imputed with sin by God, and die by their own sinning.
Pro 8:36
But he that sinneth against me wrongeth his own soul: all they that hate me love death.
Furhtermore, the promise that God does not impute sin of any parent to any offspring, nor offspring to parent, means that God cannot rightly impute any sin of another to His own Son, nor the Son to His own Father:
Eze 18:20
The soul that sinneth, it shall die. The son shall not bear the iniquity of the father, neither shall the father bear the iniquity of the son: the righteousness of the righteous shall be upon him, and the wickedness of the wicked shall be upon him.
We notice how God's words are specifically intended to counter the prophesied lie of any sinner, that would impute their own sins to God's own Son: Bearing the iniquity of another, cannot be God having the sin of the one that sinned, imputed to another than sinned not.
And so, not only by Scriptural record, but also by Scriptural law of sin and death, God Himself never had any sin imputed to His own beloved Son, who sinned not and so had no sin. But only sinful men imputed Jesus with sin and unlawful killed Him in the name of God.
And only the unbelievers in His resurrection as Son of God, still believe with His false accusers, that He was lawfully accused and condemned by God's law.
And not only they, but also any person that believes that lie, that has since been made into a false tradition of men, for sinners to be justified by killing Him on the cross, and likewise blaming it on God Himself.
1Co 12:3
Wherefore I give you to understand, that no man speaking by the Spirit of God calleth Jesus accursed:
So, you must be trying to impute Jesus with the personal sins of others, and separate that from being imputed by any personal sin of His own, as though God could do so, and yet not judge His own Son a sinner...Isaiah never says the Servant became a sinner.
Which is just another myriad of 'mystery' doctrines, used to cover the false tradition and lie, that God imputed His Son with any sin at all.
There's the mystery of the Godhead and gospel of Jesus Christ, that was hidden from the foundation of the world, and is now revealed by the prophesies and fulfillment of Scriptures.
And then there's the mysterious doctrines of men, that are magically produced out of Scriptures, that God never said nor did Himself.
The former lawfully forgives and delievers from sinning, any that repent of our own sinning against Jesus Christ, who was nailed to a tree by us that sinned against Him.
The latter unlawfully justifies the sinning of people, who still believe the lie of the devil, that God the Father imputed our own sins to the person of His dear Son, who knew no sin Himself, and yet mysteriously and devilishly made His own personal soul guilty unto death for our sinning against Him.
2Th 2:7
For the mystery of iniquity doth already work:
Rev 2:24
But unto you I say, and unto the rest in Thyatira, as many as have not this doctrine, and which have not known the depths of Satan, that they speak;
There is no Scripturally doctrional, prophetic, nor lawful way for the righteous God and the Father, to impute and condemn God the Son, Jesus Christ the righteous, with any sin at all.
Nor is their any true mystery way of imputing the soul of any person, without imputing them with personal sin, and judging them a sinful person.
