From Antiquity (Isaiah 56:1-8), the Sabbath (eSHABBAT), holy day of Jesus (Matthew 12:8; Mark 2:28; Luke 6:5), has been affirmed to have been made for all willing men to observe (Numbers 15:15-16, Leviticus 18:1-5). And it has indeed been kept in every city by the believing foreigners who joined the Jews, according to Acts 15:21.

From the book of Genesis, the sabbath day is a fixed day which starts in the evening (not at nightfall) at a specific clock time and not from a moving seasonal sunset time that falls at different times depending on the season. Jesus says that a day has 12 hours (John 11:9). Read the illustration of the use of the 12 hours in Matthew 20, in the parable of the vineyard.

The Biblical (sabbath) day is not from sunset to sunset time because a day in the book of Genesis is 'an evening and a morning', not a movable time. Sunset marks a later point in time (nightfall or darkness) as the day already started long ago in the evening at 4 PM (5 PM DST) in Jerusalem (tabulate John 19:14 versus Mark 15:25, 33).

Therefore, in the world a biblical day or sabbath day begins in the evening daylight portion before darkness announces the night fall and night portion of the day.

Keep in mind that there are some geographical areas where seasonally nightfall takes time to come, where at midnight it is still bright outside (for example in Dillingham, AK).

Do you reject the sabbath because you mistakenly claim it to be a law or that the law has been abolished or that you are not under the law? Romans 2:13 says you will not be justified before God. 

WE CAN not ESCAPE observing THE SABBATH commandment per Romans 2:12-13!

Romans 2:12-13 ASV
(12) For as many as have sinned without law shall also perish without the law: and as many as have sinned under the law shall be judged by the law;
(13) for not the hearers of the law are just before God, but the doers of the law shall be justified:

Or Do you reject the sabbath because you claim it to be a commandment not for you? One commandment less renders you guilty of all of them (James 2:10). We may not separate the COMMANDMENTS.


There is no valid argument to escape keeping the sabbath!

James 2:10 ASV
(10) For whosoever shall keep the whole law [Torah], and yet stumble in one point, he is become guilty of all.


Ezekiel 33:13 ASV
(13) When I say to the righteous, that he shall surely live; if he trust to his righteousness, and commit iniquity, none of his righteous deeds shall be remembered; but in his iniquity that he hath committed, therein shall he die.

The SABBATH (rest) day is also for foreigners, man, and son of man

ISAIAH 56:1-8 is the evidence that GOD (JESUS) appeals to each generation on earth to remember His Shabbat | Sabbath. From the declaration of Jesus in Matthew 5:17-18 and the dogma found in James 2:10, anyone who ignores anything in the Law of Moses, willfully and unknowingly (Romans 2:12-13) will not be saved. Before God became Jesus in the flesh, no one was exempt from keeping the Law of Moses, according to Isaiah 56:1-8 and Luke 15:21). 

(1) Thus saith Jehovah, Keep ye justice, and do righteousness; for my salvation is near to come, and my righteousness to be revealed.  (2)  Blessed is the man that doeth this, and the son of man that holdeth it fast; that keepeth the sabbath from profaning it, and keepeth his hand from doing any evil.  (3)  Neither let the foreigner, that hath joined himself to Jehovah, speak, saying, Jehovah will surely separate me from his people; neither let the eunuch say, Behold, I am a dry tree.  (4)  For thus saith Jehovah of the eunuchs that keep my sabbaths, and choose the things that please me, and hold fast my covenant:  (5)  Unto them will I give in my house and within my walls a memorial 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 foreigners that join themselves to Jehovah, to minister unto him, and to love the name of Jehovah, to be his servants, every one that keepeth the sabbath from profaning it, and holdeth fast my covenant;  (7)  even them will I bring to my holy mountain, and make them joyful in my house of prayer: their burnt-offerings and their sacrifices shall be accepted upon mine altar; for my house shall be called a house of prayer for all peoples.  (8)  The Lord Jehovah, who gathereth the outcasts of Israel, saith, Yet will I gather others to him, besides his own that are gathered. Isaiah 56:1-8 ASV


Advice:
Do you belong to Yeshua (Revelation 18:4)? IF YOU DO, obey Him FULLY!
YOU BELONG TO SATAN (Adversary) WHEN YOU DISAGREE WITH ANYTHING IN MOSES (John 14:21-23, Matthew 5:17-18), including the sabbath commandment (Isaiah 66:17).


The flock of Jesus may not host lawbreakers in the like the Serpent who takes a rebellious stand against any of the eternal commandments in the Bible because Jesus is not a Minister of sin, according to Galatians 2:17, and because we are called to a holy and blameless calling (Ephesians 1:4) and not to a rebellious calling (1 Samuel 15:22).

John 10:14-16 LITV
(14) I am the Good Shepherd, and I know those that are Mine, and I am known by the ones that are Mine. (15) Even as the Father knows Me, I also know the Father; and I lay down My life for the sheep. (16) And I have other sheep which are not of this fold. I must also lead those, and they will hear My voice; and there will be one flock, one Shepherd.

Those who can hear the voice of Jesus do keep ONLY the 7TH DAY Shabbat AND NOT THE OTHER OBSOLETE Sabbaths


REPETITION OF WARNING:
If we are missing just ONE commandment in our belief system, we will not be saved because we are not without sin, that is, we are not holy. The grace of Jesus is for the holy ones, according to Ezekiel 33:13-20.

Ezekiel 33:13 ASV
(13)  When I say to the righteous, that he shall surely live; if he trust to his righteousness, and commit iniquity, none of his righteous deeds shall be remembered; but in his iniquity that he hath committed, therein shall he die.
