Many are making this more difficult and harder than it really is.
Nadine, you had it right.
Simply put the Sabbath is remembering Jesus and everything he done for all of us.
Below are two articles you can read that may help.
Question: 'How is Jesus our Sabbath Rest?'
Answer: The key to understanding how Jesus is our Sabbath rest is the Hebrew word sabat, which means 'to rest or stop or cease from work.' The origin of the Sabbath goes back to Creation. After creating the heavens and the earth in six days, God 'rested on the seventh day from all His work which He had made'(Genesis 2:2). This doesn’t mean that God was tired and needed a rest. We know that God is omnipotent, literally 'all-powerful.' He has all the power in the universe, He never tires, and His most arduous expenditure of energy does not diminish His power one bit. So, what does it mean that God rested on the seventh day? Simply that He stopped what He was doing. He ceased from His labors. This is important in understanding the establishment of the Sabbath day and the role of Christ as our Sabbath rest.
God used the example of His resting on the seventh day of Creation to establish the principle of the Sabbath day rest for His people. In Ex 20:8-11 and Deut 5:12-15, God gave the Israelites the fourth of His Ten Commandments. They were to 'remember' the Sabbath day and 'keep it holy.' One day out of every seven, they were to rest from their labors and give the same day of rest to their servants and animals. This was not just a physical rest, but a cessation of laboring. Whatever work they were engaged in was to stop for a full day each week. The Sabbath day was established so the people would rest from their labors, only to begin again after a one-day rest.
The various elements of the Sabbath symbolized the coming of the Messiah, who would provide a permanent rest for His people. Once again the example of resting from our labors comes into play. With the establishment of the Old Testament Law, the Jews were constantly “laboring” to make themselves acceptable to God. Their labors included trying to obey a myriad of do’s and don’ts of the ceremonial law, the Temple law, the civil law, etc. Of course they couldn’t possibly keep all those laws, so God provided an array of sin offerings and sacrifices so they could come to Him for forgiveness and restore fellowship with Him, but only temporarily. Just as they began their physical labors after a one-day rest, so, too, did they have to continue to offer sacrifices. Hebrews 10:1 tells us that the law 'can never, by the same sacrifices repeated endlessly year after year, make perfect those who draw near to worship.' But these sacrifices were offered in anticipation of the ultimate sacrifice of Christ on the cross, who 'after He had offered one sacrifice for sins forever, sat down on the right of God' (Hebrews 10:12). Just as He rested after performing the ultimate sacrifice, He sat down and rested—ceased from His labor of atonement because there was nothing more to be done, ever. Because of what He did, we no longer have to 'labor' in law-keeping in order to be justified in the sight of God. Jesus was sent so that we might rest in God and in what He has provided.
Another element of the Sabbath day rest which God instituted as a foreshadowing of our complete rest in Christ is that He blessed it, sanctified it, and made it holy. Here again we see the symbol of Christ as our Sabbath rest—the holy, perfect Son of God who sanctifies and makes holy all who believe in Him. God sanctified Christ, just as He sanctified the Sabbath day, and sent Him into the world (John 10:36) to be our sacrifice for sin. In Him we find complete rest from the labors of our self-effort, because He alone is holy and righteous. 'God made him who had no sin to be sin for us, so that in him we might become the righteousness of God' (2 Corinthians 5:21). We can now cease from our spiritual labors and rest in Him, not just one day a week, but always.
Jesus can be our Sabbath rest in part because He is 'Lord of the Sabbath' (Mat 12:8). As God incarnate, He decides the true meaning of the Sabbath because He created it, and He is our Sabbath rest in the flesh. When the Pharisees criticized Him for healing on the Sabbath, Jesus reminded them that even they, sinful as they were, would not hesitate to pull a sheep out of a pit on the Sabbath. Because He came to seek and save His sheep who would hear His voice (John 10:3,27)and enter into the Sabbath rest He provided by paying for their sins, He could break the Sabbath rules. He told the Pharisees that people are more important than sheep and the salvation He provided was more important than rules. By saying, 'The Sabbath was made for man, not man for the Sabbath'(Mark 2:27), Jesus was restating the principle that the Sabbath rest was instituted to relieve man of his labors, just as He came to relieve us of our attempting to achieve salvation by our works. We no longer rest for only one day, but forever cease our laboring to attain God’s favor. Jesus is our rest from works now, just as He is the door to heaven, where we will rest in Him forever.
Hebrews 4 is the definitive passage regarding Jesus as our Sabbath rest. The writer to the Hebrews exhorts his readers to 'enter in' to the Sabbath rest provided by Christ. After three chapters of telling them that Jesus is superior to the angels and that He is our Apostle and High Priest, he pleads with them to not harden their hearts against Him, as their fathers hardened their hearts against Jehovah in the wilderness. Because of their unbelief, God denied that generation access to the holy land, saying, 'They shall not enter into My rest' (Hebrews 3:3:11). In the same way, the writer to the Hebrews begs them—and us—not to make the same mistake by rejecting God’s Sabbath rest in Jesus Christ. 'There remains, then, a Sabbath-rest for the people of God; for anyone who enters God's rest also rests from his own work, just as God did from his. Let us, therefore, make every effort to enter that rest, so that no one will fall by following their example of disobedience'(Hebrews 4:9-11).
There is no other Sabbath rest besides Jesus. He alone satisfies the requirements of the Law, and He alone provides the sacrifice that atones for sin. He is God’s plan for us to cease from the labor of our own works. We dare not reject this one-and-only Way of salvation (John 14:6. God’s reaction to those who choose to reject His plan is seen in Numbers 15. A man was found gathering sticks on the Sabbath day, in spite of God’s plain commandment to cease from all labor on the Sabbath. This transgression was a known and willful sin, done with unblushing boldness in broad daylight, in open defiance of the divine authority. 'And Jehovah said to Moses, ‘The man shall surely be put to death' (v. 35). So it will be to all who reject God’s provision for our Sabbath rest in Christ. 'How shall we escape if we neglect so great a salvation?' (Heb 2:3).
Question: "Does God require Sabbath-keeping of Christians?"
Answer: In Colossians 2:16-17 , the apostle Paul declares, 'Therefore do not let anyone judge you by what you eat or drink, or with regard to a religious festival, a New Moon celebration or a Sabbath day. These are a shadow of the things that were to come; the reality, however, is found in Christ.' Similarly, Romans 14:5 states, 'One man considers one day more sacred than another; another man considers every day alike. Each one should be fully convinced in his own mind.' These Scriptures make it clear that, for the Christian, Sabbath-keeping is a matter of spiritual freedom, not a command from God. Sabbath-keeping is an issue on which God’s Word instructs us not to judge each other. Sabbath-keeping is a matter about which each Christian needs to be fully convinced in his/her own mind.
In the early chapters of the book of Acts, the first Christians were predominantly Jews. When Gentiles began to receive the gift of salvation through Jesus Christ, the Jewish Christians had a dilemma. What aspects of the Mosaic Law and Jewish tradition should Gentile Christians be instructed to obey? The apostles met and discussed the issue in the Jerusalem council (Acts 15). The decision was, 'It is my judgment, therefore, that we should not make it difficult for the Gentiles who are turning to God. Instead we should write to them, telling them to abstain from food polluted by idols, from sexual immorality, from the meat of strangled animals and from blood' (Acts 15:19-20). Sabbath-keeping was not one of the commands the apostles felt was necessary to force on Gentile believers. It is inconceivable that the apostles would neglect to include Sabbath-keeping if it was God’s command for Christians to observe the Sabbath day.
A common error in the Sabbath-keeping debate is the concept that the Sabbath was the day of worship. Groups such as the Seventh Day Adventists hold that God requires the church service to be held on Saturday, the Sabbath day. That is not what the Sabbath command was. The Sabbath command was to do no work on the Sabbath day (Ex 20:8-11). Nowhere in Scripture is the Sabbath day commanded to be the day of worship. Yes, Jews in Old Testament, New Testament, and modern times use Saturday as the day of worship, but that is not the essence of the Sabbath command. In the book of Acts, whenever a meeting is said to be on the Sabbath, it is a meeting of Jews, not Christians.
When did the early Christians meet? Act 2:46-47 gives us the answer, 'Every day they continued to meet together in the temple courts. They broke bread in their homes and ate together with glad and sincere hearts, praising God and enjoying the favor of all the people. And the Lord added to their number daily those who were being saved.' If there was a day that Christians met regularly, it was the first day of the week (our Sunday), not the Sabbath day (our Saturday) (Acts 20:7;1 Corinthians 16:2). In honor of Christ’s resurrection on Sunday, the early Christians observed Sunday not as the 'Christian Sabbath', but as a day to especially worship Jesus Christ.
Is there anything wrong with worshiping on Saturday, the Jewish Sabbath? Absolutely not! We should worship God every day, not just on Saturday or Sunday! Many churches today have both Saturday and Sunday services. There is freedom in Christ (Romans 8:21; 2 Corinthians 3:17; Galatians 5:1). Should a Christian practice Sabbath-keeping, that is, not working on Saturdays? If a Christian feels led to do so, absolutely, yes (Romans 15:5). However, those who choose to practice Sabbath-keeping should not judge those who do not keep the Sabbath (Colossians 2:16). Further, those who do not keep the Sabbath should avoid being a stumbling block (1 Corinthians 8:9) to those who do keep the Sabbath. Galatians 5:13-15 sums up the whole issue: 'You, my brothers, were called to be free. But do not use your freedom to indulge the sinful nature; rather, serve one another in love. The entire law is summed up in a single command: ‘Love your neighbor as yourself.’ If you keep on biting and devouring each other, watch out or you will be destroyed by each other.'
Matthew 7
21 'Not everyone who says to Me, ‘Lord, Lord,’ shall enter the kingdom of heaven, but he who does the will of My Father in heaven. 22 Many will say to Me in that day, ‘Lord, Lord, have we not prophesied in Your name, cast out demons in Your name, and done many wonders in Your name?’ 23 And then I will declare to them, ‘I never knew you; depart from Me, you who practice lawlessness!’
Those who fall short are those who "practice lawlessness" i.e. those who do not follow the Law. Do we want to be in this group on that Day? I think not...
You're very good at only highlighting the last part, but you're forgetting the main part. Which is only he who does the will of My Father in heaven shall enter the Kingdom of God.
Now we must ask what is the will of the Father? It's easy. 'So then they said to him, 'What must we do to accomplish the deeds God requires?' Jesus replied, 'This is the deed God requires – to believe in the one whom he sent.' (John 6:28-29).
All throughout the NT, salvation is as simple as believing Jesus is God in the flesh who died in our place. I don't feel like copying quotes all day long to prove that point, but if you disagree, I can give you a link that will make my case.
Also, it is impossible to follow the law perfectly, there is only one who ever has and ever will.
'There is not a righteous man on earth who does what is right and never sins.' (Ecc 7:20) 'for all have sinned and fall short of the glory of God,' (Romans 3:23) 'For whoever keeps the whole law and yet stumbles at just one point is guilty of breaking all of it.' (James 2:10)
Also, 'For as many as are of the works of the law are under the curse: for it is written, Cursed is every one that continueth not in all things which are written in the book of the law to do them. But that no man is justified by the law in the sight of God, it is evident: for, The just shall live by faith. And the law is not of faith: but, The man that doeth them shall live in them. Christ hath redeemed us from the curse of the law, being made a curse for us: for it is written, Cursed is every one that hangeth on a tree' (Galatians 3:10-13)
'For all the law is fulfilled in one word, even in this; Thou shalt love thy neighbour as thyself.' (Galatians 5:14)
All we can do is accept that we are sinners, and thank God Almighty for sending his one and only BEGOTTEN Son do die in our place. After knowing and believing that who wouldn't love God and love others as we love ourselves.
