I understand we enter into the heavenly Holy of Holies ... the true tabernacle the Lord pitched and not man ... and we come boldly before the throne of grace that we may obtain mercy, and find grace to help in time of need.
The new covenant also states (from your Post #15):
"I will make with the house of Israel after those days, saith the Lord; I will put my laws into their mind, and write them in their hearts."
What laws does God put into the mind and write in the heart of the born again one?
And how does that truth square with 1 Tim 1:9 where God tells us knowing this, that the law is not made for a righteous man, but for the lawless and disobedient?
Throughout the Old Testament a temporary atonement for sins had been made available by way of the death of animals sacrificed annually by the High Priest. He was the only one allowed to enter into the holiest part of the Temple that symbolized the very heart of God’s presence. The High Priest would make the atonement with blood for the sin offering upon the horns that were on the altar in the most sacred chamber of the Temple. It was the holiest ceremony performed annually and carried out in service to the Lord.
Hebrews 9:8-9
The Holy Ghost this signifying, that the way into the holiest of all was not yet made manifest, while as the first tabernacle was yet standing:
Which
was a figure for the time then present, in which were offered both gifts and sacrifices, that could not make him that did the service perfect, as pertaining to the conscience;
The offering of the animals under the Old Testament Law had only temporary effects, and thereby had to be offered year after year. In the new covenant, we are sanctified through the offering of the body of Jesus Christ, who entered into the holy of holies, the glorious presence of God’s heart once and for all.
Hebrews 9:10
Which stood only in meats and drinks, and divers washings, and carnal ordinances, imposed
on them until the time of reformation.
Hebrews 9:11-14
But Christ being come an high priest of good things to come, by a greater and more perfect tabernacle, not made with hands, that is to say, not of this building;
Neither by the blood of goats and calves, but by his own blood he entered in once into the holy place, having obtained eternal redemption
for us.
For if the blood of bulls and of goats, and the ashes of an heifer sprinkling the unclean, sanctifieth to the purifying of the flesh:
How much more shall the blood of Christ, who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God?
Hebrews 9:15-21
And for this cause he is the mediator of the new testament, that by means of death, for the redemption of the transgressions
that were under the first testament, they which are called might receive the promise of eternal inheritance.
For where a testament
is, there must also of necessity be the death of the testator.
For a testament
is of force after men are dead: otherwise it is of no strength at all while the testator liveth.
Whereupon neither the first
testament was dedicated without blood.
For when Moses had spoken every precept to all the people according to the law, he took the blood of calves and of goats, with water, and scarlet wool, and hyssop, and sprinkled both the book, and all the people,
Saying, This
is the blood of the testament which God hath enjoined unto you.
Moreover he sprikled with blood both the tabernacle, and all the vessels of the ministry.
Hebrews 9:22
And almost all things are by the law purged with blood; and without shedding of blood is no remission.
It's the blood that was used on the altar to make the atonement for their souls because the life of the flesh is in the blood. And since the covenant with Israel was a covenant of blood that made the atonement for the soul, it put Israel into the category where God said He would protect them, and He would not be the one who would break the covenant of blood. There are certain universal immutable laws that were established by God for the legal requirement of the shedding of blood for redemption. Since human blood had become corrupt, it was necessary that blood be shed for remission of sin, and this is why it's a legal requirement set forth in God’s Word.
Hebrews 9:23-10:4
It
was therefore necessary that the patterns of things in the heavens should be purified with these; but the heavenly things themselves with better sacrifices than these.
For Christ is not entered into the holy places made with hands,
which are the figures of the true; but into heaven itself, now to appear in the presence of God for us:
Nor yet that he should offer himself often, as the high priest entereth into the holy place every year with blood of others;
For then must he often have suffered since the foundation of the world: but now once in the end of the world hath he appeared to put away sin by the sacrifice of himself.
And as it is appointed unto men once to die, but after this the judgment:
So Christ was once offered to bear the sins of many; and unto them that look for him shall he appear the second time without sin unto salvation.
For the law having a shadow of good things to come,
and not the very image of the things, can never with those sacrifices which they offered year by year continually make the comers thereunto perfect.
For then would they not have ceased to be offered? because that the worshippers once purged should have had no more conscience of sins.
But in those
sacrifices there is a remembrance again
made of sins every year.
For
it is not possible that the blood of bulls and goats should take away sins.
Righteousness could have come by the Old Testament Law if there had been a law given that would have given life. But the Bible clearly teaches that everyone was under sin, without God and without hope, until “the promise” that came by the faith of Jesus Christ was made available to us who believe. God never really had any pleasure in burnt offerings and sacrifices, but there was just no other way at the time to cover up for the nature of human sin.
But now in the new covenant, we are not just covered up, but we are sanctified through the offering of the body of Jesus Christ, who entered into the holy of holies, the glorious presence of God’s heart once and for all. Jesus Christ in being the ultimate sacrificial lamb had only to fulfill God’s specifications for the Passover.
The High Priest was the head of the priesthood, functioning as the head of the Temple, and the official representative between God and Israel. To carry out such a responsibility he was forbidden any impure contact that might defile him. Only he could enter once a year in the innermost part of the sanctuary of the Temple, known as the holy of holies where the sacred Ark of the Covenant was kept, to proclaim divine revelations, having the exclusive privilege of consulting God directly. Appeal to him could be made in any matter because he exercised supreme authority over the worship and the Temple, as the mediator between God and Israel.
Jesus Christ is the perfect High Priest, who took upon himself the sins of the entire world, and is the mediator of the new covenant between God and us. The Temple was a temporary place where one would go for divine blessing in building form, but now it is in Christ, who is a permanent place, where one needs to go for divine blessing because of the new covenant God has with Christ.
In the new covenant, we are sanctified through the offering of the body of Jesus Christ, who entered into heaven itself to appear in the holy of holies, the sacred chamber of the heart of God’s glorious presence for us. Jesus Christ is the promised seed and faithful High Priest, who fulfilled all the law, and is set between God and us—because he is connected to both sides, and thereby he is able to work with God and with us. My mind boggles over God’s heart of love, His compassion, and the tenderness to have Jesus Christ, who is the greatest food of all time, the bread of life, to establish a true and vital spiritual relationship between God and us.
