Has God ever exempted the aliens from keeping the Sabbath before and after Jesus? The Scriptures are clear that any converted alien must keep the Sabbath because God does not make any difference between the Jews and the Aliens (Numbers 15:15). Here are some verses that prove that God requires the observance of the Sabbath from all mankind in each generation.
(15) For the assembly, there shall be one statute for you, and for the stranger that sojourneth with you, a statute for ever throughout your generations: as ye are, so shall the stranger be before the LORD.
Isaiah 58:13 LEB
If you hold your foot back from the Sabbath, [from] doing your affairs on my [JESUS] holy day, if you call the Sabbath a pleasure, the holy [day] of Yahweh honorable, if you honor him more than doing your ways, than finding your affairs and speaking a word,
Isaiah 56:1-8 MKJV
(1) So says Jehovah, Keep judgment and do justice; for My salvation is near to come, and My righteousness to be revealed.
(2) Blessed is the man who does this, and the son of man who lays hold on it; keeping the sabbath, from defiling it; and keeping his hand from doing any evil.
(3) And do not let the son of the stranger, who has joined himself to Jehovah, speak, saying, Jehovah has utterly separated me from His people. And do not let the eunuch say, Behold, I am a dry tree.
(4) For so says Jehovah to the eunuchs who keep My Sabbath, and choose things that please Me, and take hold of My covenant;
(5) even to them will I give within My house and within My walls a hand and a name better than of sons and of daughters; I will give them an everlasting name that shall not be cut off.
(6) Also the sons of the stranger, who join themselves to Jehovah to serve Him, and to love the name of Jehovah, to be His servants, everyone who keeps from defiling the Sabbath, and takes hold of My covenant;
(7) even them I will bring to My holy mountain, and make them joyful in My house of prayer. Their burnt offerings and their sacrifices shall be accepted on My altar; for My house shall be called a house of prayer for all peoples,
(8) says the Lord Jehovah who gathers the outcasts of Israel, Yet I will gather beside him his gathered ones.
Who claims ownership of the Sabbath in the New Testament? Not God the Father.
So, EVEN FOREIGNERS TO JUDAISM WERE REQUIRED TO OBSERVE THE SABBATH DAY. JESUS WHO CREATED THE SABBATH REST AT CREATION DID NOT COMMAND ANYONE TO KEEP ANOTHER DAY, NO MATTER WHAT TWIST OF THE CROSS THE PEDDLERS OR CORRUPTORS OF THE WORD MAY USE TO TRY TO TOPPLE JESUS'S SABBATH DAY (Read Matthew 12:8).
ANYONE WHO PREACHES AGAINST THE SABBATH DAY IS A PEDDLER OR CORRUPTOR OF THE WORD BECAUSE, from the beginning, NO ONE WHO CONVERTED TO JUDAISM (CHRISTIANITY PER MATTHEW 5:17-18) WAS ever EXEMPTED FROM KEEPING THE SABBATH DAY (ISAIAH 56:1-8) AND BECAUSE 'there is no difference between Jew and Greek, for the same Lord of all is rich to all who call upon Him. Romans 10:12 EMTV'.
