The claim that the Sabbath was only an Old Covenant institution fails when Scripture's timeline is examined. The Sabbath was not introduced at Sinai. It appears before Israel existed as a nation...Genesis 2:2–3 states: "God blessed the seventh day and made it holy, because on it He rested from all the work of creating that He had done." The Sabbath is rooted in creation itself, not merely the Mosaic covenant...Then, when the Ten Commandments were given, the 4th commandment does not say "create a new Sabbath." It says: "REMEMBER the Sabbath day by keeping it holy." — Exodus 20:8 To remember something means it was already established and known...The commandment connects directly back to creation: "For in six days the LORD made the heavens and the earth... but He rested on the seventh day. Therefore the LORD blessed the Sabbath day and made it holy." — Exodus 20:11...So the biblical sequence is: Creation → Sabbath established → Israel commanded to remember → Sabbath observed. The question is not whether the Sabbath existed under the Old Covenant. It clearly did...The question is whether something established by God at creation and included in the moral law is abolished simply because the Old Covenant reached fulfillment. To also note that marriage as well was also included in the mosaic laws and establish in the days of creation but yet we do not say that marriage is fullfilled. We cant be isolating the Sabbath alone. Jesus said: "The Sabbath was made for man, not man for the Sabbath." — Mark 2:27...Notice He did not say the Sabbath was made only for Israel. The foundation of the Sabbath is creation, the command is remembrance, and its purpose predates Sinai. In the book of Revelations 1:10 “I was in the spirit in the Lord’s day” Jesus said he is Lord over the sabbath day and John is busy addressing Jesus himself when he is talking about his experience on the Lord’s day, the Lord’s day is the day Jesus is Lord over which as he said is the sabbath day thus the Lord’s day is Sabbath.
The Old Testament sabbath only applies to the creation of this earth which was a physical covenant so a physical rest.
The New Testament is a spiritual covenant so a spiritual rest.
Col 2:14 Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross;
Col 2:15 And having spoiled principalities and powers, he made a shew of them openly, triumphing over them in it.
Col 2:16 Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath days:
Col 2:17 Which are a shadow of things to come; but the body is of Christ.
Gal 3:24 Wherefore the law was our schoolmaster to bring us unto Christ, that we might be justified by faith.
Gal 3:25 But after that faith is come, we are no longer under a schoolmaster.
Jesus took the physical ordinances of Israel out of the way nailing them to His cross because they were contrary to us for they had no bearing on salvation.
So they do not apply in the New Testament which includes the sabbath days.
Which let not person judge you concerning the physical ordinances so I will not listen to them.
The ordinances were a shadow of things to come, and the physical laws was a schoolteacher until Christ came and then we are not under a schoolteacher anymore.
Isa 65:17 For, behold, I create new heavens and a new earth: and the former shall not be remembered, nor come into mind.
Rev 21:1 And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away; and there was no more sea.
Joh 14:2 In my Father's house are many mansions: if it were not so, I would have told you. I go to prepare a place for you.
Joh 14:3 And if I go and prepare a place for you, I will come again, and receive you unto myself; that where I am, there ye may be also.
Luk 17:20 And when he was demanded of the Pharisees, when the kingdom of God should come, he answered them and said, The kingdom of God cometh not with observation:
Luk 17:21 Neither shall they say, Lo here! or, lo there! for, behold, the kingdom of God is within you.
Heb 11:13 These all died in faith, not having received the promises, but having seen them afar off, and were persuaded of them, and embraced them, and confessed that they were strangers and pilgrims on the earth.
Heb 11:16 But now they desire a better country, that is, an heavenly: wherefore God is not ashamed to be called their God: for he hath prepared for them a city.
This heaven and earth will pass away and there will be a new heaven and earth which is the place Jesus went away to prepare for the saints.
The saints belong to that heaven and earth and celebrate that.
Isa 28:10 For precept must be upon precept, precept upon precept; line upon line, line upon line; here a little, and there a little:
Isa 28:11 For with stammering lips and another tongue will he speak to this people.
Isa 28:12 To whom he said, This is the rest wherewith ye may cause the weary to rest; and this is the refreshing: yet they would not hear.
Mat 11:28 Come unto me, all ye that labour and are heavy laden, and I will give you rest.
Mat 11:29 Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls.
Mat 11:30 For my yoke is easy, and my burden is light.
In the New Testament it is a spiritual rest yet many will not hear but they want to judge people saying keep the physical sabbath which they do not have to keep.
Mat 19:16 And, behold, one came and said unto him, Good Master, what good thing shall I do, that I may have eternal life?
Mat 19:17 And he said unto him, Why callest thou me good? there is none good but one, that is, God: but if thou wilt enter into life, keep the commandments.
Mat 19:18 He saith unto him, Which? Jesus said, Thou shalt do no murder, Thou shalt not commit adultery, Thou shalt not steal, Thou shalt not bear false witness,
Mat 19:19 Honour thy father and thy mother: and, Thou shalt love thy neighbour as thyself.
Rom 13:8 Owe no man any thing, but to love one another: for he that loveth another hath fulfilled the law.
Rom 13:9 For this, Thou shalt not commit adultery, Thou shalt not kill, Thou shalt not steal, Thou shalt not bear false witness, Thou shalt not covet; and if there be any other commandment, it is briefly comprehended in this saying, namely, Thou shalt love thy neighbour as thyself.
Rom 13:10 Love worketh no ill to his neighbour: therefore love is the fulfilling of the law.
Jesus told the rich man to follow the commandments that have to do with loving people to inherit eternal life for love is the fulfilling of the law and does not mention keep the sabbath day for eternal life.
They had to keep the sabbath while Jesus was on earth for the Old Testament was still in affect.
But after Jesus shed His blood to give salvation we no longer go by the physical sabbath.
The New Testament does not say keep the physical sabbath but says it is taken out of the way.
Mrk 2:27 And he said unto them, The sabbath was made for man, and not man for the sabbath.
Man was not made for the sabbath but the sabbath was made for man so it can change.
Which it changed to a spiritual rest.
Or will you judge and not hear.
