Jesus, the perfect expression of God
As God the Son, the Second Divine Person in the Triune Godhead, Who is God, Jesus was United with the Human Body God had Elected and Prepared for Him.
As the Virgin Born Godman, Jesus was the Perfect Expression of God, Who Lived a Perfect Life under the Universal Moral Law of God.
God did not have an innate Attribute of Righteousness which had been Tried and Lived out under His Universal Moral Law, until Jesus was Perfectly Obedient to all the Demands of the Law.
By Living His Life Perfectly under God's Law, Jesus became the End of the Law for Righteousness.
That Righteous Life Jesus Accomplished was what was Sacrificed to God.
The life of the flesh is in the blood.
Jesus Righteous Human Body and Righteous Soul were Made an Offering for sin, that was the sins God's Chosen Elect were guilty of, having broken God's Law and Offended His Holiness.
The Wrathful Rod of Justice for having Infinite sin Charged to the account of His children God Gave Jesus to Save would have Smitted them and been Poured Out as their cup to drink Forever in the Lake of Fire had its Just Satisfaction Accomplished by the Reverse Correllary of the Punishment they deserved Poured Out on the Perfectly Righteous Son of God on the cross.
The Account of the guilt of all the sins of God's Elect were Imputed to Jesus as the Wrathful Rod of Justice Smitted Jesus' Righteous Body and Soul to Death.
The wages of sin was death, when the Lord Laid on Him the Iniquity of us all who were to be Saved, and Jesus Laid Down His Perfectly Righteous Life for His sheep, and Died the Just for the unjust.
Nothing more fully proves Christ's Free and Full Assent and Consent to do the Will of His Father, Proposed in the Doctrine of the Eternal Covenant of Grace, than His actual Performance of it.
Was it God's Will that Jesus should take the Care and Charge of all God's Elect, and lose none? Jesus has Done it, #Joh 17:12.
Was it God's Will that Jesus should Assume Human Nature? the Word has been made flesh, and Dwelt among men, #Joh 1:14.
Was it God's Will that Jesus should Obey the Law? he is become the End of the Law for Righteousness, #Ro 10:4.
Was it God's Will that Jesus should suffer Death, the Penalty of the Law? Jesus has Suffered, the Just for the unjust, to Bring them to God, #1Pe 3:18.
Was it God's Will that Jesus should Make Himself an Offering for sin? He has Given Himself to God, an Offering and a Sacrifice, of a Sweet Smelling Savour, #Eph 5:2.
In a word, Was it God's Will l that Jesus should Redeem His people from all their Iniquities? Yes, Jesus has Obtained an Eternal Redemption for them, by His Resurrection from Death, #Heb 9:12.
With our redemption God addressed the heart, and our rebirth ultimately fulfilled the law.
Jesus' Righteousness He Accomplished by Living Perfectly under the Law of God in a Human Body and Soul, once He was Made the End of the Law for Righteousness, was then Imputed to the lost sinner when they were Regenerated by the Holy Spirit in their New Birth.
Once that saved soul is Imputed with Jesus' Righteous Life, they have no sin which can be Judged by God and are, therefore, Pardoned and Wholly Justified from the Law.
With Jesus' Righteous Redemption of the sinner's deceitful, God hating heart, He addressed them as Hellbound sinners, when Jesus Gave His Righteous Life He had Lived Out under God's Law and became the End of the Law for Righteousness.
God addressed the heart of the sinner who's mind was at emnity against God through Jesus' Redemption because He had a Righteous Life to Give, after JESUS FULFILLED THE LAW.
Your statement skips Jesus having Fulfilled the Law by His Perfect Life, and credits the sinner's New Birth with having Fulfilled the Law, but not before skipping the crediting of the sinful State of sinners to sinners who are without hope, without Jesus the Savior.
