There are some today who teach that keeping the Seventh-day Sabbath is binding upon Christians today. Are they correct? Should we be worshipping God on the seventh day instead of the first day of the week? Let’s see what the Bible teaches.
Let’s start at the beginning, in Genesis chapter 2.
“By the seventh day God completed His work which He had done, and He rested on the seventh day from all His work which He had done. Then God blessed the seventh day and sanctified it, because in it He rested from all His work which God had created and made.” (Genesis 2:2, 3 NASB)
There is nothing, however, in the biblical record, that says that Jehovah directed Adam to keep the Sabbath himself. In fact, in Deuteronomy 5:15, Israel is told that the Sabbath was given, not to commemorate creation, but their deliverance from Egypt!
“You shall remember that you were a slave in the land of Egypt, and the LORD your God brought you out of there by a mighty hand and by an outstretched arm; therefore the LORD your God commanded you to observe the sabbath day.” (Deuteronomy 5:15 NASB)

In spite of this, many will argue that the Mosaic Law was divided into “moral” and “ceremonial” sections, and that only the ceremonial law was done away. The contents is that the moral law, or Ten Commandments, are still in force and binding on us today. Let’s see if Jesus considered them separate or not in Matthew 5:21-38.
Verse 21: “You have heard that the ancients were told, ‘YOU SHALL NOT COMMIT MURDER’ and ‘Whoever commits murder shall be liable to the court.’ (Part of the Ten Commandments)
Verse 23: Therefore if you are presenting your offering at the altar, and there remember that your brother has something against you, (Not part of the Ten Commandments)
Verse 27: “You have heard that it was said, ‘YOU SHALL NOT COMMIT ADULTERY’; (Part of the Ten Commandments)
Verse 31: “It was said, ‘WHOEVER SENDS HIS WIFE AWAY, LET HIM GIVE HER A CERTIFICATE OF DIVORCE’; (Not part of the Ten Commandments)
Verse 38: “You have heard that it was said, ‘AN EYE FOR AN EYE, AND A TOOTH FOR A TOOTH.’ (Not part of the Ten Commandments)
You see, Jesus mixed the two types of law freely, because in verse 17 he had stated that he came to fulfill the Law, not just a part of it.

So, if the Law is in one piece and not divided, are Christians bound to keep the Ten Commandments? What does Romans 7:6-7 say?
“But now we have been released from the Law, having died to that by which we were bound, so that we serve in newness of the Spirit and not in oldness of the letter. What shall we say then? Is the Law sin? May it never be! On the contrary, I would not have come to know sin except through the Law; for I would not have known about coveting if the Law had not said, “YOU SHALL NOT COVET.” (Romans 7:6, 7 NASB)

Not only does it say that we are released from the Law, but it cites the Tenth Commandment as being part of that Law! And Paul, in 2 Corinthians 3:7-11 writes this:
“But if the ministry of death, written and engraved on stones, was glorious, so that the children of Israel could not look steadily at the face of Moses because of the glory of his countenance, which glory was passing away, how will the ministry of the Spirit not be more glorious? For if the ministry of condemnation had glory, the ministry of righteousness exceeds much more in glory. For even what was made glorious had no glory in this respect, because of the glory that excels. For if what is passing away was glorious, what remains is much more glorious.” (2 Corinthians 3:7-11 NKJV)
Did you catch that? He directly speaks of that which was written in stone (i.e. the Ten Commandments) as that which was “passing away”!

So, since Jesus came to fulfill the Law, how did He fulfill the Sabbath? Hebrews 4:4-11 puts it this way:
“For He has spoken in a certain place of the seventh day in this way: And God rested on the seventh day from all His works ; and again in this place: They shall not enter My rest. Since therefore it remains that some must enter it, and those to whom it was first preached did not enter because of disobedience, again He designates a certain day, saying in David, Today, after such a long time, as it has been said: Today, if you will hear His voice, Do not harden your hearts. For if Joshua had given them rest, then He would not afterward have spoken of another day. There remains therefore a rest for the people of God. For he who has entered His rest has himself also ceased from his works as God did from His. Let us therefore be diligent to enter that rest, lest anyone fall according to the same example of disobedience.” (Hebrews 4:4-11 NKJV)

So what are we resting from now that we, as Christians, are the people of God? Our works! We have ceased trying to show ourselves righteous by our own works, and now have entered into that true sabbath rest by doing God’s work instead. We are created for good works in Christ, and we no longer have to work to somehow earn God’s approval!
And now that we are free from keeping ANY of the Old Law, we can walk in the reality of Christ. We are no longer obligated to keep yearly festivals, monthly new moons, or weekly sabbaths. We can walk in the reality instead of the shadow.
So let no one judge you in food or in drink, or regarding a festival or a new moon or sabbaths, which are a shadow of things to come, but the substance is of Christ. (Colossians 2:16, 17 NKJV)
