Commandment to Adam not to eat from the tree, commandment to Noah to build the ark, commandment to Abram to leave his country and to move to another one, commandment to Israel to keep Sabbath... There are many commandments of God that do not apply today.
We are to keep the commandments that are given to us. And we are not given any commandment to observe the Sabbath or to keep the Mosaic Law.
Why are you isolating the Sabbath commandment, when God did not? Yes God gave a command to Noah to build an ark and its a silly comparison to compare that to God not wanting His people to profane HIS holy day and part of God's eternal commandments written in stone by His own finger now in the hearts and minds of His people. Hebrews 8:10
If the Sabbath goes all of God's commandments go because
God said, we cannot add or subtract to His commandments Duet 4:2. God placed together this unit of Ten, these are His works Exodus 32:16 and specifically blessed the Sabbath commandment and no man can reverse Numbers 23:20, no matter how much they want to
How many other commandments are we free to break from God's unit of Ten? The Ten Commandments are not suggestions or multiple choice. If you break one you break them all. James 2:10-12
God made individual covenants with His people, but made a Nation-wide covenant with Israel His chosen people, God never made a covenant with Gentiles and if we are in Christ we are grafted into God's chosen people through our faith Gal 2:26-28.
Exodus 20
And God spoke all these words, saying:
2 “I
am the Lord your God, who brought you out of the land of Egypt, out of the house of bondage.
3 “You shall have no other gods before Me.
4 “You shall not make for yourself a carved image—any likeness
of anything that
is in heaven above, or that
is in the earth beneath, or that
is in the water under the earth; 5 you shall not bow down to them nor serve them. For I, the Lord your God,
am a jealous God, visiting the iniquity of the fathers upon the children to the third and fourth
generations of those who hate Me, 6
but showing mercy to thousands, to those who love Me and keep My commandments.
7 “You shall not take the name of the Lord your God in vain, for the Lord will not hold
him guiltless who takes His name in vain.
8 “Remember the Sabbath day, to keep it holy. 9 Six days you shall labor and do all your work, 10 but the seventh day
is the Sabbath of the Lord your God.
In it you shall do no work: you, nor your son, nor your daughter, nor your male servant, nor your female servant, nor your cattle,
nor your stranger who is within your gates. 11 For
in six days the Lord made the heavens and the earth, the sea, and all that
is in them, and rested the seventh day. Therefore the Lord blessed the Sabbath day and hallowed it.
12 “Honor your father and your mother, that your days may be long upon the land which the Lord your God is giving you.
13 “You shall not murder.
14 “You shall not commit adultery.
15 “You shall not steal.
16 “You shall not bear false witness against your neighbor.
17 “You shall not covet your neighbor’s house; you shall not covet your neighbor’s wife, nor his male servant, nor his female servant, nor his ox, nor his donkey, nor anything that
is your neighbor’s.”
