Sort of like keeping the spirit of the 6th commandment which allows you to be a serial killer? So long as you don't get angry, therefore you can ignore the letter of the law?
That wouldn't be the spirit of the law, but the opposite. And the writer is not meaning spirit like the essence of the law, but as lead by the Holy
Spirit. Can you do that with the 4th commandment without being taught the rules? No. You know it is only by the letter of the law. But Jeremiah 31:31-34 shows us that no man needs to be taught. Why? Because it is the Royal laws that are written on our hearts, the la. James 2:8
As Phoneman says below...we are to rest on Sabbath as God did.
God can't get tired. That is not the Spirit of the law. It was the first thing that God created to later point to the Redeemer from before the foundation of the world. It then became a ceremonial law given only to the Jews, but the substance always pointed to Christ. There is no record of anyone before being taught to keep the Sabbath. Not even Abraham, Isaac or Jacob who both obeyed His voice as did Enoch and Noah. Only the Children of Israel was God's chosen nation predestined as His.
Where is the text that says God unblessed the Sabbath day? See 1 Chron. 17:27
1 Chron. 17:27 has to do with David's kingdom and his heir Jesus Christ. It has nothing to do with the Sabbath. It appears that your whole focus is on a Day, and mine is on the Substance.
b. Luke, in writing his gospel decades later says in
Luke 23:56 "according to the commandment". How come they kept and observed the Sabbath according to the commandment if it was no longer a commandment?
"55 And the women who had come with Him from Galilee followed after, and they observed the tomb and how His body was laid. 56 Then they returned and prepared spices and fragrant oils. And they rested on the Sabbath according to the commandment."
Hebrews 9:16
For where there
is a testament, there must also of necessity be the
death of the testator.
If you are mentioned in a will, when can you claim the money? Answer: when the will is read. It was read on the Day of Pentecost, not before, so the women were doing nothing wrong as they were still under the Old Covenant.
c. Why is it that none of the gospel writers, every one of whom penned their work decades after the resurrection, know less about the covenants and the law than you do seeing none of them spoke of any new day of worship or the abolition of the Sabbath day?
They were writing to people who were living the first century beliefs. You would think that if the Sabbath LAW was changed to Sunday as LAW it would be written about wouldn't you? But you don't understand that it was no longer a LAW to be kept by the letter so was not part of Christianity. Remember, In fact, they met DAILY.
Acts of the Apostles 2:46-47
46 So continuing daily with one accord in the temple, and breaking bread from house to house, they ate their food with gladness and simplicity of heart, 47 praising God and having favor with all the people. And the Lord added to the church daily those who were being saved.
d. If the old covenant law that needed to be replaced because it was faulty, are you saying the Tec Commandments which God Himself wrote on stone, was faulty?
Anything that God wrote is holy. But God wrote them to be kept by a faulty flesh like to kindergartners. But the flesh made them always fumble on the one law of the heart, the 10th. So they could never be as holy as the One who wrote them. That experience is in Romans 7:7-25.
They were fashioned after the Royal Law, but basically dumbed down because of our sin nature. That is why Paul wrote:
Romans 3:
23 for all have sinned and fall short of the glory of God, 24 being justified freely by His grace through the redemption that is in Christ Jesus, 25 whom God set forth
as a propitiation by His blood, through faith, to demonstrate His righteousness, because
in His forbearance God had passed over the sins that were previously committed, 26 to demonstrate at the present time His righteousness, that He might be just and the justifier of the one who has faith in Jesus.
Now we can be holy as the Father is holy. Hebrews 12:14.
You didn't actually respond to any of the points I've been making, but simply regurgitating your own, so maybe you could answer the above with some semblance of Biblical relevance?
I hope I've been plain enough for you to finally understand and graduate to the New Covenant.
