Paul supports my statement here:
Gal 3:24 Wherefore the law was our schoolmaster to bring us unto Christ, that we might be justified by faith. 25 But after that faith is come, we are no longer under a schoolmaster.
The Old Covenant of Law was given to the Nation of Israel to be their schoolmaster to lead them to Christ.
Someone who disregarded everything that their schoolmaster taught them after they graduated would be missing the whole point of a schoolmaster. In Exodus 33:13, Moses wanted God to be gracious to him by teaching him to walk in His way that he and Israel might know Him, and in Matthew 7:23, Jesus said that he would tell those who are workers of lawlessness to depart from him because he never knew them, so the goal of the law is to graciously teach us how to know God and Jesus by teaching us to walk in His way, which is His gift of eternal life (John 17:3). In other words, goal of God's Word is to lead us to God's Word made flesh because he is the embodiment of it, but it does not lead us to him so that we can then reject everything that he is and go back to being doers of what it reveals to be wickedness. In Matthew 4:15-23, Jesus began his ministry with the Gospel message to repent for the Kingdom of God is at hand, which was a light to the Gentiles, and the Law of God was how his audience knew what sin is (Romans 3:20), so repenting from our disobedience to it is a central part of the Gospel message, which is in accordance with Jesus being sent as the promised seed to bless us by turning us from our wickedness (Acts 3:25-26).
The Old Covenant stipulated that as long as the nation obeyed God's law, they would be acceptable to Him. However, the Nation of Israel had no ability to be obedient to God because they were spiritually marred.
Again, nowhere does nowhere does the Bible say that, but rather it states the opposite. In Romans 10:5-8, Paul referred to Deuteronomy 30 as the word of faith that we proclaim in regard to the righteousness that is by faith proclaiming that the Law of God is not too difficult for us to obey and that obedience to it brings life and a blessing while disobedience brings death and a curse, so choose life! Moreover, there are many example of people in the Bible who did keep the law, such as with those in Joshua 22:1-3, Luke 1:5-6, Revelation 14:12, and Revelation 22:14.
The temple sacrifices were put in place to put a temporary covering over their sins. Christ came to be the permanent sacrifice. In this way, Christ fulfilled the Old Covenant of Law.
In Matthew 5:17-19, Jesus said that he came to fulfill the law in contrast with saying that he came not to abolish it and he warned against relaxing the least part of it, so you should not interpret Jesus fulfilling the law is meaning no, he actually came to abolish or relax parts of it.
But since Christ's sacrifice on the cross did nothing to stop mankind's sinful ways, Christ introduced a new covenant. In that new covenant, Christ will do all the work of making mankind obedient to the laws of God. He does this by spiritually changing mankind by giving each person the free gift of the Holy Spirit. With the Holy Spirit, mankind will be governed by the Spirit and will cease sinning. So yes, the Law of God is not too difficult to obey because Jesus Christ has come and given us the Spirit which causes us to "will and to do". After a person is converted, they will enter into the rest of Christ and will be obeying the Sabbath day law.
Entering God's rest does not involve rejecting God's instructions for how to enter into His rest It does not mean that we should no longer obey God's command to keep the 7th day holy, or to refrain from committing murder, idolatry, adultery, theft, rape, favoritism, kidnapping, or set aside any of God's other commands.
Scriptural repentance is a repentance from works. The other side of that coin is faith. The Old Covenant is works based. The New Covenant is based on faith in Christ to do all the works of making us righteous before God. After a person has been converted, they will be governed by the Spirit and will eventually stop sinning once they have matured to a "man of full age". At that time, the person be like Christ and will have perfect obedience. Their obedience comes from the Spirit and not from themselves. That spiritual change is mankind's salvation.
Scripture never calls us to repent from our obedience to the Law of God, but rather it consistently calls for us to repent from our sin, which is our transgressions of the Law of God. We can't be made righteous before God even as the result of having perfect obedience to the Law of God because it was never given as a way of making us righteous in the first place (Romans 4:1-5), so the position that Christ does all the works of making us righteous before God is a fundamental misunderstanding of how we are made righteous. The concept of faith is not foreign to the OT and it is a fundamental misunderstanding of faith to create that false dichotomy.
The Bible frequently connects our faith in God with our obedience to Him, such as with James 2:17-18 saying that faith without works is dead and that he would show his faith through his works. In Matthew 23:23, Jesus said that faith is one of the weightier matters of the Law of God. In Romans 1:5, we have received grace in order to bring about the obedience of faith. In Romans 3:31, our faith upholds the Law of God. In John 3:16-21, it connect our belief in the Son with our obedience. In Psalm 119:29-30, he chose the way of faith by setting the Law of God before him. In Revelation 14:12, those who kept faith in Jesus are the same as those who kept God's commandments. In Hebrews 11, every example of faith is an example of works, so in the OT had faith just as people in the NT do. In Hebrews 3:18-19, it equates unbelief with disobedience. In Numbers 5:6, it describes breaking the Law of God as breaking faith. And so forth.
You are missing the point I was making. Yes, we are to follow the commandments of God. The Old Covenant is based upon mankind's own ability to follow the Law and the New Covenant is based upon Christ's ability to follow the Law. After a person is converted, Christ will live within them via the Holy Spirit and cause them to "will and to do". This will cause the person to rest from their own works because Christ within them is now doing all the works. When this change occurs within a person, the Sabbath Day law is then spiritually fulfilled within the person. They will then rest 24/7 from their works.
The Law of God was never given as something to be obeyed on our own apart from Christ. Our own works would be works that we do on our own that are completely independent of anything that God has instructed. It is contradictory to think that we can rely on ourselves by relying on God's instructions.
A physical rest from work one day a week is no longer necessary.
That is not stated anywhere in the Bible, but rather it is contrary to it. The reason why Israelites did not under into God's rest is because they were not keeping the 7th day holy, it doesn't work for you to try to use entering into God's rest in order to justify the same disobedience that prevented the Israelites from entering God's rest.
Consider this scripture again:
Heb 4:10 For he that is entered into his rest, he also hath ceased from his own works (24/7), as God did from his (on the 7th day).
The Sabbath Day is based upon God resting on the seventh day after the six days of His creation work. Paul equates that same day with entering into the rest of Christ. This spiritual change within a person fulfills the physical observance of the Sabbath Day law.

Again, in Hebrews 4:9-11, there remains a Sabbath rest for the people of God, we should rest form our work as God rested from his, and we should be careful to enter into God's rest so that no one might fall away by the same sort of disobedience, so we should continue to keep the 7th day holy in accordance with the example that Christ set for us to follow. We can't enter into God's rest instead of following God's instructions for how to do that.
