"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 (New Testament!)
Note the words of Jesus himself in Luke and also Matthew below:
"Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them. I tell you the truth, until heaven and earth disappear, not the smallest letter, not the least stroke of a pen, will by any means disappear from the Law until everything is accomplished."
Matthew 5. (New Testament!)
Here Jesus is quite specifically saying that he has not come to do away with the law or the prophets and that the law shall stand until this present Earth and Universe disappear and all has been accomplished. All is a pretty big word and there can be no mistake about what the Messiah meant with this plain statement of fact. Heaven and Earth are still here! Jesus was saying he had come to fulfill the law, to fill them up or to make clear. If you read through the rest of this chapter Jesus makes very clear what the commandments are about, the true intent of the commandments not just the physical aspect of keeping the commandments but actually what it was all about and why it was so significant.
Jesus confirmed that the Law of Moses The Old Testament and commandments were to be observed and that he had not come to do away with them only to fulfil them.
Jesus was Jewish. The only book and law that Jesus was talking about was the Old Testament [the Tanakh] and the commandments as that is what they had in their hand at the time, the New Testament had not yet been written. Jesus followed the Law during his life all Ten Commandments Gods Law handed down to Moses on Mount Sinai for all nations to abide by and confirmed that nothing would disappear from the law. The New Testament is different because it is for individuals not nations and how they should live their lives as individuals in relation to each other. The Old Testament and New Testament are both 100% valid (the whole bible) and is what Christians should follow.
All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness. 2 Timothy 3:16
The above passage in 2 Timothy confirms that ALL scripture is inspired by God.
Above all, you must understand that no prophecy of Scripture came about by the prophet's own interpretation. 2 Peter 1:20
This confirms that all scripture was not the prophets or mans own interpretation but it was direct from God.
Gods day of rest the Sabbath has never changed, it has always remained the same and occurred from Friday sunset to Saturday sunset.
Sunday worship is not called for anywhere in the Bible. Sunday worship is Church doctrine not what Jesus said or practiced during his life. Christians are commanded to keep the Sabbath day holy (the biblical Sabbath of Friday sunset to Saturday sunset) as kept by Jesus and his disciples during their lifetimes, not any other day. Sunday worship is a false custom. Keeping the Sabbath holy is the true custom of Christ and his followers and is Gods Holy day of rest for all nations and all people who believe in him.
This is more of what Jesus said concerning the Tanakh [Old Testament] in Matthew 5:
"Anyone who breaks one of the least of these commandments and teaches others to do the same will be called least in the kingdom of heaven, but whoever practices and teaches these commands will be called great in the kingdom of heaven. For I tell you that unless your righteousness surpasses that of the Pharisees and the teachers of the law, you will certainly not enter the kingdom of heaven." Matthew 5:19-21 (New Testament!)
What Jesus said was quite clear, that we must keep the Tanakh [Old Testament] and Ten Commandments, that he had not come to abolish them and that unless we obey and keep the Tanakh [Old Testament] and Commandments to a level equal to the priests and teachers of the Law "The Pharisees" then we would not enter the Kingdom of Heaven. He also confirmed that anyone who breaks the least of the Commandments and teaches others to do the same would be called "least" in the Kingdom of Heaven, and that's providing they get there in the first place. This was only if they broke the least of the Commandments! The fourth commandment is to Keep the Sabbath day holy (Friday Sunset to Saturday Sunset).
We know Jesus died for us, but some say that this all changed when he died.
"Then they went home and prepared spices and perfumes." Luke 23:56 (New Testament!)
Here the women are preparing spices and perfume to put on Jesus body. Remember here that Jesus has died.
"But they rested on the Sabbath in obedience to the commandment." Luke 23:56 (New Testament!)
You have to remember that the writer of this book wrote many years after Jesus died, but he is pointing out the Sabbath command right here. And these women who were taught by Jesus while he was alive, they have no new understanding about the Sabbath day. They're continuing to keep the Sabbath that they kept when Jesus was around, which is the biblical Sabbath, the 7th day Sabbath of Friday sunset to Saturday sunset. There is absolutely no change that we see here in your Bible.
You can even find more evidence in the Book of Acts which details the beginning of the New Testament Christian Church. Here in the Book of Acts you can get a look at what they were doing in that New Testament Church after Jesus' death.
"As his custom was, Paul went into the synagogue, and on three Sabbath days he reasoned with them from the Scriptures" Acts 17:2 (New Testament!)
You can argue about this and say that Paul was going into the synagogue here and just dealing with Jewish people and of course the Jews were continuing to keep the Sabbath day, but what this shows is the link between the Sabbath at the beginning of time, the Sabbath at the time of Moses, the Sabbath at the time of Jesus and the Sabbath here in the New Testament time of the Church, and Paul one of the Apostles is continuing to go into the Synagogue on the Sabbath and preach about G-d and about the Scriptures. There doesn't appear to be any break in the Sabbath in the Bible!
You can argue anything you want about history and things that occurred later, but here I am looking at scripture because I am living by the Word of G-d. I believe that this is what followers of Jesus should do, is live by G-ds Word, and the record in the Word of God is that there was no change in the Sabbath. You will see this throughout your Bible from beginning to End, the Sabbath is what the Sabbath is. It continues on and on and one throughout the pages of your Bible without any major change occurring.
"Every Sabbath he reasoned in the synagogue, trying to persuade Jews and Greeks." Acts 18:4 (New Testament!)
The interesting thing about this is that there are some Greeks on the scene here. Paul was in Greece at this time and there may have been Jewish synagogues in Greece, but why were these Greeks going to a Jewish synagogue? Why were they not in a church or something else worshipping G-d, worshipping Christ? It seems like the Greeks are following the Jewish lead here in the keeping of the Sabbath day and going and worshipping G-d on that same day! And Paul was now there in Greece, and he says in black and white that everything is exactly the same as it has been before. He is still keeping the Sabbath Day. He is observing it and also teaching and preaching on the Sabbath Day, the Biblical Sabbath Day.
The Early Christian Church continued to keep the Biblical Sabath. But slowly over time when you get into the later part of the first century of Christianity you find some Christians moving away from the Sabbath to a Sunday observance. Some of the reasoning behind it had to do with the destruction of the Jewish temple in Jerusalem when the Romans came down hard on them. Many of the Christians who were also observing the Sabbath and holy days were also being persecuted because they worshipped in a similar manner to the Jews of that time. And some of them began to move away from the Sabbath because they were not crazy about being persecuted. Most of these people were in the Western Church. The Eastern Church continued to observe Sabbath for a lot longer than those in the Western part of the Kingdom. So when you get into the hundreds plus A.D. you start to see a movement more and more away from G-ds Holy day the Sabbath. But did G-d ever ask you to move away from this Sabbath day? Did Jesus ever say to move away from his Sabbath day? No! Absolutely not. Man said lets move away from the Sabbath and go to Sunday. Then in 325 A.D. Emperor Constantine made it a law that Sunday was the day of worship. Constantine never had any authority though to change the day of worship from G-ds Holy Day the Sabbath to a Sunday.
Throughout history there have been followers of Christ and Christians who have continued to keep the correct day the Sabbath day and there continues to be today.
Below I am quoting to you from Isaiah 66. You might not be convinced by me quoting from the Old Testament but you must realise that when the Apostles and writers of the New Testament were quoting the scriptures the only thing they were quoting from was the Old Testament.
"As the new heavens and the new earth that I make will endure before me," declares the LORD, "so will your name and descendants endure. From one New Moon to another and from one Sabbath to another, all mankind will come and bow down before me," says the LORD." Isaiah 66
Understand the context here, the context of that is the End Times! This is the Kingdom of G-d being set up, and he says that people are going to worship him on his Sabbath Day! What Sabbath is that? It's the Biblical Sabbath of Friday sunset to Saturday sunset, there is absolutely no doubt about it. You see this at the beginning of your bible instituted at creation, you see it with Moses, you see it with Jesus, you see it with the Apostles, we also see it in the future Kingdom! The Sabbath matters. It is the specific day that G-d wants us to observe his rest. So why not do it?
