Either the author of the Book of Hebrews is confused, or you are confused.
Christ's Sacrifice Once for All (from eSword)
Heb 10:1 For the law, having a shadow of the good things to come, and not the very image of the things, can never with these same sacrifices, which they offer continually year by year, make those who approach perfect.
Heb 10:2 For then would they not have ceased to be offered? For the worshipers, once purified, would have had no more consciousness of sins.
Heb 10:3 But in those sacrifices there is a reminder of sins every year.
Heb 10:4 For it is not possible that the blood of bulls and goats could take away sins.
Heb 10:5 Therefore, when He came into the world, He said: "SACRIFICE AND OFFERING YOU DID NOT DESIRE, BUT A BODY YOU HAVE PREPARED FOR ME.
Heb 10:6 IN BURNT OFFERINGS AND SACRIFICES FOR SIN YOU HAD NO PLEASURE.
Heb 10:7 THEN I SAID, 'BEHOLD, I HAVE COME—IN THE VOLUME OF THE BOOK IT IS WRITTEN OF ME—TO DO YOUR WILL, O GOD.' "
Heb 10:8 Previously saying, "SACRIFICE AND OFFERING, BURNT OFFERINGS, AND OFFERINGS FOR SIN YOU DID NOT DESIRE, NOR HAD PLEASURE IN THEM" (which are offered according to the law),
Heb 10:9 then He said, "BEHOLD, I HAVE COME TO DO YOUR WILL, O GOD." He takes away the first that He may establish the second.
Heb 10:10 By that will we have been sanctified through the offering of the body of Jesus Christ once for all.
Heb 10:11 And every priest stands ministering daily and offering repeatedly the same sacrifices, which can never take away sins.
Heb 10:12 But this Man, after He had offered one sacrifice for sins forever, sat down at the right hand of God,
Heb 10:13 from that time waiting till His enemies are made His footstool.
Heb 10:14 For by one offering He has perfected forever those who are being sanctified.
Heb 10:15 But the Holy Spirit also witnesses to us; for after He had said before,
Heb 10:16 "THIS IS THE COVENANT THAT I WILL MAKE WITH THEM AFTER THOSE DAYS, SAYS THE LORD: I WILL PUT MY LAWS INTO THEIR HEARTS, AND IN THEIR MINDS I WILL WRITE THEM,"
Heb 10:17 then He adds, "THEIR SINS AND THEIR LAWLESS DEEDS I WILL REMEMBER NO MORE."
Heb 10:18 Now where there is remission of these, there is no longer an offering for sin.
Is the Atonement to remove sin or is the Atonement to remove the Law?
The Law was just rules. The sacrifices did not remove sin. The sacrifices removed the punishment for breaking the Law.
The Atonement was for sin. Having a future law without sin does not need sin to make it stronger. It was the Law that made sin stronger. An iron rule can have a Law and sacrifices and have nothing to do with sin at all. Sin existed prior to the Law, so neither need each other. Sin did not need the Law, the Law just made sin stronger. The Law does not need sin, it only is a set of rules.
12 Here is how it works: it was through one individual that sin entered the world, and through sin, death; and in this way death passed through to the whole human race, inasmuch as everyone sinned.
13 Sin was indeed present in the world before
Torah was given, but sin is not counted as such when there is no
Torah.
14 Nevertheless death ruled from Adam until Moshe, even over those whose sinning was not exactly like Adam’s violation of a direct command. In this, Adam prefigured the one who was to come.
Adam violated a direct command prior to sin. Paul said death ruled over those before the Law and sin was different than Adam's disobedience. Why does the Torah change things (but sin is not counted as such when there is no
Torah)? Because death was a natural occurrence at any time. The Law gave humans a right to punishment, even death, allegedly before one's naturally appointed time. The strength of sin by the Law was death, or an economy of control (sacrifices). Humans could use the Law to control sin and others because they naturally sinned. Thus compounding sin.
Take away sin. There is still control and a Law, and the economy of a law, sacrifices. Death is determined by God, who knows even the thoughts we have. Incorruptible bodies, does not preclude no one can think any more. Incorruptible bodies are there because no more decay and death. Sin is removed to remove the slave aspect nature of sin. Christ is the ruler, because, no mention of human thought police. The natural tendency would be to avoid even rebellion in one's thoughts. Why is rebellion as the sin of witchcraft?
“Does
Adonai take as much pleasure
in burnt offerings and sacrifices
as in obeying what
Adonai says?
Surely obeying is better than sacrifice,
and heeding orders than the fat of rams."
“For rebellion is like the sin of sorcery,
stubbornness like the crime of idolatry.
Because you have rejected the word of
Adonai,
he too has rejected you as king.”
The literal interpretation is Saul made the excuse of his disobedience to make a sacrifice. The point is still clear. Obedience is better than the sin the sacrifice covers. Rebellion is not a sin in as much as breaking a single law. Obedience is much better than sin and breaking a law, thus avoiding the sacrifice altogether. Witchcraft is giving one's self to Satan to thwart the whole Law itself.
Yes the Atonement did away with the Law, in regards to the economy. It even covered sin and the punishment of death. That does not mean God cannot remove sin, and have 1,000 years of life without sin. Nor will having a Law and sacrifices change the fact sin is gone or needed.
Remember Cain and Abel in the Garden? Sacrifices did not atone for sin, there was no sin. It was outside the door. They were an offering to God, without sin as a factor. A limited economy where Cain could have made a trade with Abel and offered up the same sacrifices.
Revelation 7:15
“Day and night they serve him in his Temple"
What is the service in a Temple? This is the Garden of Eden. There is still an alter there.
Who is claiming God is bringing back the Law of Moses? That is no longer necessary, because we have the Law of Christ, even with an iron rod. The Law of Moses only worked under sin.
