Hebrews 8:1-6 AV:
1 Now of the things which we have spoken this is the sum:
We have such an high priestJesus the Man, who is set on the right hand of the throne of the Majesty in the heavens;
2 A minister of the sanctuary, and of the true tabernacle, which the Lord pitched, and not man.
3 For every high priest is ordained to offer gifts and sacrifices: wherefore it is of necessity that this man have somewhat also to offerHis Blood.
4 For if he were on earth, he should not be a priest, seeing that there are priests that offer gifts according to the law:
5 Who serve unto the example and shadow of heavenly things, as Moses was admonished of God
when he was about to make the tabernacle: for,
See, saith he, that thou make all things according to the pattern shewed to thee in the mount.(Ex. 25:17,40)6 But now hath heJesus obtained a more excellent ministryas our High Priest, by how much also he is the mediator of a better covenantthe New,
Blood sacrifices of substitutionally accepted innocent animals were made by sinful God-seeking, confessing, repenting, Jehovah-obeying men from the time of Adam and Eve's first Sin and Fall. But through Abraham, Isaac, and Jacob God selected a particular family of people to be his priests, and show to the watching world the only process by which His righteous demands had to be satisfied so that He might again extend the invitation of fallible human beings into His fellowship and that of His Son (1 Cor. 1:9) as friends.
So under the law and its provisions established through Moses, God unilaterally instructed them how the atonement for their committed sins must be performed. All of this involved both blood sacrifices and plant-based sacrifices. The purpose of the scheme of sin-atonement under the Law was to illustrate what God required, and that is death of the human for any sin committed, of which the proof would be the exsanguination of the criminal. But under the Law, God showed the particularized method by which the substitutionary sacrifices could be made, culminating in an offering of animal blood, placed on the Mercy Seat that covered The Ark of the covenant, which was permanently placed in the Holy of Holies of the Tabernacle, pursuant to the explicit instructions given to Moses, and written down for their meticulous replication.
One feature of this process was that the Priest of all priests, the High Priest, was to perform this sacrifice of blood, but even then, only once a year, every year, as long as the Mosaic Covenant lasted.
Please note that however long this intermediate reign of the Law was permitted, still it was only temporary, and it was done temporally, and used symbols representing the True Sacrifice and Final Accountability that must eventually and finally be resolved, in the Presence of Almighty God, in His Place of Residence, in the Holy of Holies of Heaven itself.
Thus though in the world Jesus of Nazareth, slated from before the creation of the earth to be the Sacrificial Lamb of God, did complete the task of being born as a human, living a sinless life, and dying a substitutionary death on the part of all mankind, of which He was one, was perfectly finished, that opus in itself did not suffice to save other humans from death and Hell. His Work had to be reviewed, approved, and accepted by The God the Judge of all, with verdict pronounced.
That He shed the totally acceptable sacrificial Human Blood, though required, that submission to blood-letting was not sufficient, either.
What was necessary is that, in truth, as shown by the yearly rehearsal of the fallible earthly high priests of old on Yom Kippur, He as the Ultimate, Final, and Permanent Human High Priest should take His Shed Blood, enter the Heavenly Holy of Holies with it, and place it upon the Heavenly Mercy Seat for the assessment of the Mighty God and Judge of all men, awaiting His final verdict.
That Jesus The Man and High Priest did perform, and thus received the verdict and commendation from the Father, "Well done, Thou Good and Faithful Servant." By it God the Judge was propitiated, His Wrath slaked, His Anger stilled; whereupon He The Father was proactively willing to reconcile His created subjects to Himself.
It is that One-Time Offering of Jesus' Blood that completed His Heavenly Duties; and without that,the transaction of the Sin Debt being paid and accepted by the Mighty God, with Reconciliation being offered to such other humans as would accept the terms, would not have been finalized.
You were not aware of this?
Yup; but what simple point are you trying to make?
Of that; I am NOT aware.
