The SABBATH GO's BACK TO creation, Not to MOSES Hand writings, Which was a shadow, But the SABBATH is HOLY unto the LORD, And We will even KEEP it in the NEW HEAVEN AND THE NEW EARTH,ISAIAH 66:22-23, I HOPE GOD straighten you out ON walking on HIS HOLY SABBATH DAY, GOD made it HOLY and it is STILL HOLY, AND THERES IS NOTHING YOU CAN DO TO MAKE IT UNHOLY, BUT FOR yourself, GOD blessed it and it will remain BLESSED, PRAISE GOD FOR HIS SABBATH DAY. Isaiah 56:2 BLESSED IS THE MAN, NOT JEWS THAT receives HIS SABBATH, The Sabbath was before there was JEWS, JESUS says that the Sabbath was for MAN, Again man and not JEWS.
GOD bless as HE sees fit
In regards to Isaiah 66:22-23, this merely teaches that from month to month and from week to week, God’s people will worship Him. In the new heaven and the new earth, we read there will have no need of the sun or moon, there will be no night there, but one perpetual day and the glory of God will illuminate it. (Revelation 21:23-25). How then could there be a cycle of seven days that would allow for literally keeping the weekly sabbath day under the law? The Isaiah passage simply means that God’s people will perpetually worship Him in contrast to keeping the weekly sabbath day under the law.
Furthermore, if you insist on sabbath observances based on Isaiah 66:23, then you also need to observe
new moons as well. Yet from what I hear, most Sabbatarian’s don’t observe new moons, which is inconsistent. New moons require night, hence Sabbatarians have night in heaven, yet there is no day and night cycles in heaven. You cannot have "new moon to new moon" or "sabbath days" without day and night, so your argument is moot. Will there be Levital priests in the new heaven? If Isaiah 66:23 teaches that we will keep the sabbath day in the new heaven, then it also teaches in Isaiah 66:21 that the Levitical priests will be in the new heaven, because it is also mentioned. What happened to the Levitical priesthood under the new covenant terms?
Priesthood changed so did the law. Hebrews 7:12 - For when the priesthood is changed, the law must be changed also.
*The old and new covenants do not mix.
In regards to Isaiah 56:2, foreigners were to "join themselves to the Lord;" and "love the name of the Lord;" and "be his servants;" and "take hold of God's covenant." The OLD COVENANT. But to do this they had to be circumcised, for God said: “No foreigner uncircumcised in heart and uncircumcised in flesh, of all the foreigners who are among the sons of Israel, shall enter My sanctuary." (Ezekiel 44:9). When Gentiles thus "joined themselves to the Lord" they CEASED BEING GENTILES and became proselytes to the Jewish religion. They kept the Sabbath AS JEWISH PROSELYTES, NOT as Gentiles.
But WHERE ARE GENTILES as Gentiles ever commanded to keep the Sabbath? Furthermore, if the Sabbath was of universal application, why were the Gentiles called "strangers?" The apostle Paul, speaking of the Gentiles during the Jewish age, says they were
"strangers from the covenants of promise, having no hope, and without God in the world?" (Ephesians 2:12).
And when God gave the Sabbath commandment at Sinai, why did he make it binding ONLY on "the stranger that is within your gates?" (Exodus 20:10). Where is the passage that proves the Sabbath was binding on the Gentile OUTSIDE the gates? All this shows the Sabbath was NOT universally applied. If it had been, there would have been no "strangers from the covenants of promise."
*The Word of God makes it quite clear that Sabbath observance was a
sign between God and Israel:“The Israelites are to observe the Sabbath, celebrating it for the generations to come as a lasting covenant. It will be a
sign between me and the Israelites forever, for in six days the Lord made the heavens and the earth, and on the seventh day he abstained from work and rested” (Exodus 31:16-17).
*In Deuteronomy 5, Moses restates the Ten Commandments to the next generation of Israelites. Here, after commanding Sabbath observance in verses 12–14, Moses gives the reason the Sabbath was given to the nation Israel:
“Remember that you were slaves in Egypt and that the Lord your God brought you out of there with a mighty hand and an outstretched arm. Therefore the Lord your God has commanded you to observe the Sabbath day.” (Deuteronomy 5:15)
