Of all the words of Jesus on earth, only 4 references are made of the sabbath.
    Matthew 12.8 - For the Son of man is Lord even of the sabbath day
    Matthew 24.20 - But pray ye that your flight be not in the winter, neither on the sabbath day:
    Mark 2.27-28 - 27  And he said unto them, The sabbath was made for man, and not man for
the sabbath: 28  Therefore the Son of man is Lord also of the sabbath.
    Luke 6.5 - And he said unto them, That the Son of man is Lord also of the sabbath.

3)
The old Jewish sabbath was part of the contract between God and Israel and a token and a sign of that covenant.
    Exodus 20.8-11 - 8  Remember the sabbath day, to keep it holy. 9  Six days shalt thou labour, and do all thy work: 10  But the seventh day is the sabbath of the LORD thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, thy manservant, nor thy maidservant, nor thy cattle, nor thy stranger that is within thy gates: 11  For in six days the LORD made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the LORD blessed the sabbath day, and hallowed it.
    Exodus 31.13-18 - 13  Speak thou also unto the children of Israel, saying, Verily my sabbaths ye shall keep: for it is a sign between me and you throughout your generations; that ye may know that I am the LORD that doth sanctify you. 14  Ye shall keep the sabbath therefore; for it is holy unto you: every one that defileth it shall surely be put to death: for whosoever doeth any work therein, that soul shall be cut off from among his people. 15  Six days may work be done; but in the seventh is the sabbath of rest, holy to the LORD: whosoever doeth any work in the sabbath day, he shall surely be put to death. 16  Wherefore the children of Israel shall keep the sabbath, to observe the sabbath throughout their generations, for a perpetual covenant. 17  It is a sign between me and the children of Israel for ever: for in six days the LORD made heaven and earth, and on the seventh day he rested, and was refreshed. 18  And he gave unto Moses, when he had made an end of communing with him upon mount Sinai, two tables of testimony, tables of stone, written with the finger of God.
    Ezekiel 20.12-20 - 12  Moreover also I gave them my sabbaths, to be a sign between me and them, that they might know that I am the LORD that sanctify them. 13  But the house of Israel rebelled against me in the wilderness: they walked not in my statutes, and they despised my judgments, which if a man do, he shall even live in them; and my sabbaths they greatly polluted: then I said, I would pour out my fury upon them in the wilderness, to consume them. 14  But I wrought for my name’s sake, that it should not be polluted before the heathen, in whose sight I brought them out. 15  Yet also I lifted up my hand unto them in the wilderness, that I would not bring them into the land which I had given them, flowing with milk and honey, which is the glory of all lands; 16  Because they despised my judgments, and walked not in my statutes, but polluted my sabbaths: for their heart went after their idols. 17  Nevertheless mine eye spared them from destroying them, neither did I make an end of them in the wilderness. 18  But I said unto their children in the wilderness, Walk ye not in the statutes of your fathers, neither observe their judgments, nor defile yourselves with their idols: 19  I am the LORD your God; walk in my statutes, and keep my judgments, and do them; 20  And hallow my sabbaths; and they shall be a sign between me and you, that ye may know that I am the LORD your God.
The contract was not made with men before Moses,
    Deuteronomy 5.2-3 - 2  The LORD our God made a covenant with us in Horeb. 3  The LORD made not this covenant with our fathers, but with us, even us, who are all of us here alive this day.
or with Gentiles and the Church.
    Romans 2.14 - For when the Gentiles, which have not the law, do by nature the things contained in the law, these, having not the law, are a law unto themselves:
    Deuteronomy 4. 7-10 - 7  For what nation is there so great, who hath God so nigh unto them, as the LORD our God is in all things that we call upon him for? 8  And what nation is there so great, that hath statutes and judgments so righteous as all this law, which I set before you this day? 9  Only take heed to thyself, and keep thy soul diligently, lest thou forget the things which thine eyes have seen, and lest they depart from thy heart all the days of thy life: but teach them thy sons, and thy sons’ sons; 10  Specially the day that thou stoodest before the LORD thy God in Horeb, when the LORD said unto me, Gather me the people together, and I will make them hear my words, that they may learn to fear me all the days that they shall live upon the earth, and that they may teach their children.
The sabbath was not for them.

4)
The 4th commandment was the only one of the ten that was a ceremonial, and not a moral law. Its sole purpose was to commemorate the deliverance from Egyptian bondage when Israel had no rest.
    Deuteronomy 5.15 - And remember that thou wast a servant in the land of Egypt, and that the LORD thy God brought thee out thence through a mighty hand and by a stretched out arm: therefore the LORD thy God commanded thee to keep the sabbath day.
It was only a type of future and eternal rest.
    Colossians 2.14-17 - 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; 15  And having spoiled principalities and powers, he made a shew of them openly, triumphing over them in it. 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: 17  Which are a shadow of things to come; but the body is of Christ.
    Hebrews 4.1-11 - 1  Let us therefore fear, lest, a promise being left us of entering into his rest, any of you should seem to come short of it. 2  For unto us was the gospel preached, as well as unto them: but the word preached did not profit them, not being mixed with faith in them that heard it. 3  For we which have believed do enter into rest, as he said, As I have sworn in my wrath, if they shall enter into my rest: although the works were finished from the foundation of the world. 4  For he spake in a certain place of the seventh day on this wise, And God did rest the seventh day from all his works. 5  And in this place again, If they shall enter into my rest. 6  Seeing therefore it remaineth that some must enter therein, and they to whom it was first preached entered not in because of unbelief: 7  Again, he limiteth a certain day, saying in David, To day, after so long a time; as it is said, To day if ye will hear his voice, harden not your hearts. 8  For if Jesus had given them rest, then would he not afterward have spoken of another day. 9  There remaineth therefore a rest to the people of God. 10  For he that is entered into his rest, he also hath ceased from his own works, as God did from his. 11  Let us labour therefore to enter into that rest, lest any man fall after the same example of unbelief.
    Hebrews 10.1 - For the law having a shadow of good things to come, and not the very image of the things, can never with those sacrifices which they offered year by year continually make the comers thereunto perfect.
It was natural for the sabbath to be left out of the new contract when the reality of rest came, of which it was a shadow.
    Matthew 11.28-29 - 28  Come unto me, all ye that labour and are heavy laden, and I will give you rest. 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.
    Colossians 2.14-17 - 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; 15  And having spoiled principalities and powers, he made a shew of them openly, triumphing over them in it. 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: 17  Which are a shadow of things to come; but the body is of Christ.
The physical and spiritual benefits of a rest can be realized on any other day as well as on Saturday or Sunday!

5)
The 4th commandment was the only one that could degenerate into a mere form without affecting the morals of men. All others concern moral obligations of men. It is the only one of the ten that could be done away with, and still leave a moral law for men.

6)
God foretold and promised He would do away with the old Jewish sabbath.
    Hosea 2.11 - I will also cause all her mirth to cease, her feast days, her new moons, and her sabbaths, and all her solemn feasts.
    Isaiah 1.10-15 - 10  Hear the word of the LORD, ye rulers of Sodom; give ear unto the law of our God, ye people of Gomorrah. 11  To what purpose is the multitude of your sacrifices unto me? saith the LORD: I am full of the burnt offerings of rams, and the fat of fed beasts; and I delight not in the blood of bullocks, or of lambs, or of he goats. 12  When ye come to appear before me, who hath required this at your hand, to tread my courts? 13  Bring no more vain oblations; incense is an abomination unto me; the new moons and sabbaths, the calling of assemblies, I cannot away with; it is iniquity, even the solemn meeting. 14  Your new moons and your appointed feasts my soul hateth: they are a trouble unto me; I am weary to bear them. 15  And when ye spread forth your hands, I will hide mine eyes from you: yea, when ye make many prayers, I will not hear: your hands are full of blood.

7)
The prophets predicted that God would abolish the old and make a new covenant.
    Isaiah 42.6 - I the LORD have called thee in righteousness, and will hold thine hand, and will keep thee, and give thee for a covenant of the people, for a light of the Gentiles;
    Isaiah 49.8 - Thus saith the LORD, In an acceptable time have I heard thee, and in a day of salvation have I helped thee: and I will preserve thee, and give thee for a covenant of the people, to establish the earth, to cause to inherit the desolate heritages;
    Isaiah 59.21 - As for me, this is my covenant with them, saith the LORD; My spirit that is upon thee, and my words which I have put in thy mouth, shall not depart out of thy mouth, nor out of the mouth of thy seed, nor out of the mouth of thy seed’s seed, saith the LORD, from henceforth and for ever.
    Jeremiah 31.31-40 - 31  Behold, the days come, saith the LORD, that I will make a new covenant with the house of Israel, and with the house of Judah: 32  Not according to the covenant that I made with their fathers in the day that I took them by the hand to bring them out of the land of Egypt; which my covenant they brake, although I was an husband unto them, saith the LORD: 33  But this shall be the covenant that I will make with the house of Israel; After those days, saith the LORD, I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people. 34  And they shall teach no more every man his neighbour, and every man his brother, saying, Know the LORD: for they shall all know me, from the least of them unto the greatest of them, saith the LORD: for I will forgive their iniquity, and I will remember their sin no more. 35  Thus saith the LORD, which giveth the sun for a light by day, and the ordinances of the moon and of the stars for a light by night, which divideth the sea when the waves thereof roar; The LORD of hosts is his name: 36  If those ordinances depart from before me, saith the LORD, then the seed of Israel also shall cease from being a nation before me for ever. 37  Thus saith the LORD; If heaven above can be measured, and the foundations of the earth searched out beneath, I will also cast off all the seed of Israel for all that they have done, saith the LORD. 38  Behold, the days come, saith the LORD, that the city shall be built to the LORD from the tower of Hananeel unto the gate of the corner. 39  And the measuring line shall yet go forth over against it upon the hill Gareb, and shall compass about to Goath. 40  And the whole valley of the dead bodies, and of the ashes, and all the fields unto the brook of Kidron, unto the corner of the horse gate toward the east, shall be holy unto the LORD; it shall not be plucked up, nor thrown down any more for ever.
    Jeremiah 32.37-44 - 37  Behold, I will gather them out of all countries, whither I have driven them in mine anger, and in my fury, and in great wrath; and I will bring them again unto this place, and I will cause them to dwell safely: 38  And they shall be my people, and I will be their God: 39  And I will give them one heart, and one way, that they may fear me for ever, for the good of them, and of their children after them: 40  And I will make an everlasting covenant with them, that I will not turn away from them, to do them good; but I will put my fear in their hearts, that they shall not depart from me. 41  Yea, I will rejoice over them to do them good, and I will plant them in this land assuredly with my whole heart and with my whole soul. 42  For thus saith the LORD; Like as I have brought all this great evil upon this people, so will I bring upon them all the good that I have promised them. 43  And fields shall be bought in this land, whereof ye say, It is desolate without man or beast; it is given into the hand of the Chaldeans. 44  Men shall buy fields for money, and subscribe evidences, and seal them, and take witnesses in the land of Benjamin, and in the places about Jerusalem, and in the cities of Judah, and in the cities of the mountains, and in the cities of the valley, and in the cities of the south: for I will cause their captivity to return, saith the LORD.
That this referred to the New Testament is clear in:
    Romans 11.25-29 - 25  For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel, until the fulness of the Gentiles be come in. 26  And so all Israel shall be saved: as it is written, There shall come out of Sion the Deliverer, and shall turn away ungodliness from Jacob: 27  For this is my covenant unto them, when I shall take away their sins. 28  As concerning the gospel, they are enemies for your sakes: but as touching the election, they are beloved for the fathers’ sakes. 29  For the gifts and calling of God are without repentance.
    Hebrews 8.8-12 - 8  For finding fault with them, he saith, Behold, the days come, saith the Lord, when I will make a new covenant with the house of Israel and with the house of Judah: 9  Not according to the covenant that I made with their fathers in the day when I took them by the hand to lead them out of the land of Egypt; because they continued not in my covenant, and I regarded them not, saith the Lord. 10  For this is the covenant that I will make with the house of Israel after those days, saith the Lord; I will put my laws into their mind, and write them in their hearts: and I will be to them a God, and they shall be to me a people: 11  And they shall not teach every man his neighbour, and every man his brother, saying, Know the Lord: for all shall know me, from the least to the greatest. 12  For I will be merciful to their unrighteousness, and their sins and their iniquities will I remember no more.
    Hebrews 10.16-18 - 16  This is the covenant that I will make with them after those days, saith the Lord, I will put my laws into their hearts, and in their minds will I write them; 17  And their sins and iniquities will I remember no more. 18  Now where remission of these is, there is no more offering for sin.
    Matthew 26.28 - For this is my blood of the new testament, which is shed for many for the remission of sins.

8)
In no passage is it stated that men should keep the Jewish sabbath to commemorate the old creation rest. It was to commemorate deliverance from Egypt.
    Deuteronomy 5.15 - And remember that thou wast a servant in the land of Egypt, and that the LORD thy God brought thee out thence through a mighty hand and by a stretched out arm: therefore the LORD thy God commanded thee to keep the sabbath day.
This was what they were to "remember"
    Exodus 20.8 - Remember the sabbath day, to keep it holy.

9)
It is the only commandment that could be, and has been broken without breaking a moral law. Israel marched on that day;
    Numbers 33.3 - And they departed from Rameses in the first month, on the fifteenth day of the first month; on the morrow after the passover the children of Israel went out with an high hand in the sight of all the Egyptians.
    Leviticus 23.5-11 - 5  In the fourteenth day of the first month at even is the LORD’S passover. 6  And on the fifteenth day of the same month is the feast of unleavened bread unto the LORD: seven days ye must eat unleavened bread. 7  In the first day ye shall have an holy convocation: ye shall do no servile work therein. 8  But ye shall offer an offering made by fire unto the LORD seven days: in the seventh day is an holy convocation: ye shall do no servile work therein. 9  And the LORD spake unto Moses, saying, 10  Speak unto the children of Israel, and say unto them, When ye be come into the land which I give unto you, and shall reap the harvest thereof, then ye shall bring a sheaf of the firstfruits of your harvest unto the priest: 11  And he shall wave the sheaf before the LORD, to be accepted for you: on the morrow after the sabbath the priest shall wave it.
    Joshua 6.12-16 - 12  And Joshua rose early in the morning, and the priests took up the ark of the LORD. 13  And seven priests bearing seven trumpets of rams’ horns before the ark of the LORD went on continually, and blew with the trumpets: and the armed men went before them; but the rereward came after the ark of the LORD, the priests going on, and blowing with the trumpets. 14  And the second day they compassed the city once, and returned into the camp: so they did six days. 15  And it came to pass on the seventh day, that they rose early about the dawning of the day, and compassed the city after the same manner seven times: only on that day they compassed the city seven times. 16  And it came to pass at the seventh time, when the priests blew with the trumpets, Joshua said unto the people, Shout; for the LORD hath given you the city.
Set up the tabernacle:
    Exodus 40-1-17 - 1  And the LORD spake unto Moses, saying, 2  On the first day of the first month shalt thou set up the tabernacle of the tent of the congregation. 3  And thou shalt put therein the ark of the testimony, and cover the ark with the vail. 4  And thou shalt bring in the table, and set in order the things that are to be set in order upon it; and thou shalt bring in the candlestick, and light the lamps thereof. 5  And thou shalt set the altar of gold for the incense before the ark of the testimony, and put the hanging of the door to the tabernacle. 6  And thou shalt set the altar of the burnt offering before the door of the tabernacle of the tent of the congregation. 7  And thou shalt set the laver between the tent of the congregation and the altar, and shalt put water therein. 8  And thou shalt set up the court round about, and hang up the hanging at the court gate. 9  And thou shalt take the anointing oil, and anoint the tabernacle, and all that is therein, and shalt hallow it, and all the vessels thereof: and it shall be holy. 10  And thou shalt anoint the altar of the burnt offering, and all his vessels, and sanctify the altar: and it shall be an altar most holy. 11  And thou shalt anoint the laver and his foot, and sanctify it. 12  And thou shalt bring Aaron and his sons unto the door of the tabernacle of the congregation, and wash them with water. 13  And thou shalt put upon Aaron the holy garments, and anoint him, and sanctify him; that he may minister unto me in the priest’s office. 14  And thou shalt bring his sons, and clothe them with coats: 15  And thou shalt anoint them, as thou didst anoint their father, that they may minister unto me in the priest’s office: for their anointing shall surely be an everlasting priesthood throughout their generations. 16  Thus did Moses: according to all that the LORD commanded him, so did he. 17  And it came to pass in the first month in the second year, on the first day of the month, that the tabernacle was reared up.
with:
    Leviticus 23.5-11 - 5  In the fourteenth day of the first month at even is the LORD’S passover. 6  And on the fifteenth day of the same month is the feast of unleavened bread unto the LORD: seven days ye must eat unleavened bread. 7  In the first day ye shall have an holy convocation: ye shall do no servile work therein. 8  But ye shall offer an offering made by fire unto the LORD seven days: in the seventh day is an holy convocation: ye shall do no servile work therein. 9  And the LORD spake unto Moses, saying, 10  Speak unto the children of Israel, and say unto them, When ye be come into the land which I give unto you, and shall reap the harvest thereof, then ye shall bring a sheaf of the firstfruits of your harvest unto the priest: 11  And he shall wave the sheaf before the LORD, to be accepted for you: on the morrow after the sabbath the priest shall wave it
Searched Canaan
    Numbers 13.25 - And they returned from searching of the land after forty days.
and made war.
    1 Kings 20.29 - And they pitched one over against the other seven days. And so it was, that in the seventh day the battle was joined: and the children of Israel slew of the Syrians an hundred thousand footmen in one day.
    2 Kings 3.9 - So the king of Israel went, and the king of Judah, and the king of Edom: and they fetched a compass of seven days’ journey: and there was no water for the host, and for the cattle that followed them.
    Joshua 6.12-16 - 12  And Joshua rose early in the morning, and the priests took up the ark of the LORD. 13  And seven priests bearing seven trumpets of rams’ horns before the ark of the LORD went on continually, and blew with the trumpets: and the armed men went before them; but the reward came after the ark of the LORD, the priests going on, and blowing with the trumpets. 14  And the second day they compassed the city once, and returned into the camp: so they did six days. 15  And it came to pass on the seventh day, that they rose early about the dawning of the day, and compassed the city after the same manner seven times: only on that day they compassed the city seven times. 16  And it came to pass at the seventh time, when the priests blew with the trumpets, Joshua said unto the people, Shout; for the LORD hath given you the city.
David and others broke it and were blameless.
    Matthew 12.2-5 - 2  But when the Pharisees saw it, they said unto him, Behold, thy disciples do that which is not lawful to do upon the sabbath day. 3  But he said unto them, Have ye not read what David did, when he was an hungred, and they that were with him; 4  How he entered into the house of God, and did eat the shewbread, which was not lawful for him to eat, neither for them which were with him, but only for the priests? 5  Or have ye not read in the law, how that on the sabbath days the priests in the temple profane the sabbath, and are blameless?

10)
The day early Christians observed, not by commandment but by choice, was the first day, Sunday. However, if Jesus became the Sabbath buy His sacrifice upon the cross, does that not make us obligated to celebrate each and every day? How can we profess Jesus as our Lord, and only visit Him on Sunday mornings and Wednesday nights?
    Romans 14.1-13 - 1  Him that is weak in the faith receive ye, but not to doubtful disputations. 2  For one believeth that he may eat all things: another, who is weak, eateth herbs. 3  Let not him that eateth despise him that eateth not; and let not him which eateth not judge him that eateth: for God hath received him. 4  Who art thou that judgest another man’s servant? to his own master he standeth or falleth. Yea, he shall be holden up: for God is able to make him stand. 5  One man esteemeth one day above another: another esteemeth every day alike. Let every man be fully persuaded in his own mind. 6  He that regardeth the day, regardeth it unto the Lord; and he that regardeth not the day, to the Lord he doth not regard it. He that eateth, eateth to the Lord, for he giveth God thanks; and he that eateth not, to the Lord he eateth not, and giveth God thanks. 7  For none of us liveth to himself, and no man dieth to himself. 8  For whether we live, we live unto the Lord; and whether we die, we die unto the Lord: whether we live therefore, or die, we are the Lord’s. 9  For to this end Christ both died, and rose, and revived, that he might be Lord both of the dead and living. 10  But why dost thou judge thy brother? or why dost thou set at nought thy brother? for we shall all stand before the judgment seat of Christ. 11  For it is written, As I live, saith the Lord, every knee shall bow to me, and every tongue shall confess to God. 12  So then every one of us shall give account of himself to God. 13  Let us not therefore judge one another any more: but judge this rather, that no man put a stumblingblock or an occasion to fall in his brother’s way. 14  I know, and am persuaded by the Lord Jesus, that there is nothing unclean of itself: but to him that esteemeth any thing to be unclean, to him it is unclean.
    Galatians 4.9-11 - 9  But now, after that ye have known God, or rather are known of God, how turn ye again to the weak and beggarly elements, whereunto ye desire again to be in bondage? 10  Ye observe days, and months, and times, and years. 11  I am afraid of you, lest I have bestowed upon you labour in vain.
    Colossians 2.14-17 - 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; 15  And having spoiled principalities and powers, he made a shew of them openly, triumphing over them in it. 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: 17  Which are a shadow of things to come; but the body is of Christ.
    John 20.1 - 1 The first day of the week cometh Mary Magdalene early, when it was yet dark, unto the sepulchre, and seeth the stone taken away from the sepulchre.
    John 20.19 - Then the same day at evening, being the first day of the week, when the doors were shut where the disciples were assembled for fear of the Jews, came Jesus and stood in the midst, and saith unto them, Peace be unto you.
    1 Corinthians 16.2 - Upon the first day of the week let every one of you lay by him in store, as God hath prospered him, that there be no gatherings when I come.

To obey is better than sacrifice,
I want more than Sundays and Wednesday nights.
'Cause if you can't come to me every day,
Then don't bother coming at all!
