Jason you have taken the above scripture out of CONTEXT. I hope you do not mind I hope to show why in this post only sent as a help. The verse you have quoted says nowhere that God's Sabbath is no more.
The OLD COVENANT included both God's eternal law (10 Commandments) and the shadow laws from the Mosaic book of the covenant (Exodus 34:26; Exodus 24:7) together they made up the OLD COVENANT and God's plan of salvation. The Shadow laws from the BOOK of the law *Deuteronomy 31:26, held a different pupose to the 10 Commandments. God's LAW was the KNOWLEDGE of GOOD and Evil; SIN and RIGHTOUSNESS (Romans 3:20; Psalms 19:7-9) while the Shadow laws from the BOOK of the COVENANT provided the laws for remission of sin [FORGIVENESS] if God's eternal law was broken (Leviticus 16; sin offerings). You mix up the Shadow laws from the BOOK of the covenant with God's eternal laws (10 Commandments).
Now let's look at the scripture context you left out of the scripture you posted above from Hebrews 10:9 to examine what is the topic of conversation?
HEBREWS 10:1-12
[1], 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 ones approaching perfect.
Note: CONTEXT. What law are we talking about here? It is it God's 10 Commandments or the Mosaic shadow laws from the MOSAIC book of the law (Deuteronomy 31:26; Leviticus 16)? It is the Shadow laws from the Moasiac book of the covenant * EXODUS 24:7
[2], For then would they not have ceased to be offered? because the worshipers once purged should have had no more consciousness of sins.
[3], But in those sacrifices there is a remembrance again made of sins every year [Great day of Atonemen (Leviticus 23:27-32).
[4], For it is not possible that the blood of bulls and of goats should take away sins. [Leviticus 16 from the Mosaic book of the laws for remission of sin]
[5], Therefore when he comes into the world, he says, Sacrifice and offering you desired not, but a body have you prepared me:
[6], In burnt offerings and sacrifices for sin you have had no pleasure.
[7], Then said I, Lo, I come (in the volume of the book it is written of me,) to do your will, O God.
Note: we are not talking about God's eternal law (10 Commandments) here it is what is written in the VOLUME OF THE BOOK in relation to the Shadow laws v1 of the MOSAIC BOOK OF THE COVENANT (Exodus 24:7; Heberws 10:1)
[8], Above when he said, Sacrifice and offering and burnt offerings and offering for sin you desired not, neither had pleasure in them; which are offered by the law; [What law? Leviticus 16 from the Mosaic book of the law (Covenant) Exodus 24:7]
[9], Then said he, Lo, I come to do your will, O God. He takes away the first, that he may establish the second.
Note: CONTEXT considered so far, what is being taken away here? The SHADOW LAWS from the MOSAIC BOOK of the COVENANT that are fulfilled and pointed to JESUS in the NEW COVENANT. NOT THE 10 COMMANDMENTS! contunues...
[10], By the which will we are sanctified through the offering of the body of Jesus Christ once for all.
[11], And every priest stands daily ministering and offering frequently the same sacrifices, which can never take away sins:
[12], But this man, after he had offered one sacrifice for sins forever, sat down on the right hand of God;
..............
CONCLUSION: Yep no more sin offerings from the Shadow laws from the MOSAIC BOOK OF THE COVENANT (Exodus 24:7) This is not talking about God's eternal law (10 Commandments) being taken away. It is talking about the SHADOW laws from the volume of the book that was written about him. The MOSAIC BOOK OF THE COVENANT. No more animal sacrifices that pointed to Jesus and God's plan of salvation in the NEW COVENANT.
Can you see the context you left out trying to apply this to God's 10 commandments (4th Commandment Sabbath Exodus 20:8-11)? The above is in reference to the shadow laws for remission of sin [forgiveness] under the MOSAIC BOOK of the OLD COVENANT. Not any of God's 10 Commandments.
Hope this helps Jason.
