The Sabbath was introduced in Exodus chapter sixteen as part of the manna gathering. The Ten Commandments are in Exodus chapter twenty. It's not likely that the Israelites had forgotten about the Sabbath in four chapters. They had been observing it every week as part of their manna gathering. The "remember" does not mean what you are claiming.
Sin before Adam and Eve (transgression of Gods law in heaven - 10 Commandments)
Ezekiel 28:15-16 (talking about Satan here)
15“You were blameless in your ways
From the day you were created
Until unrighteousness was found in you.
16“By the abundance of your trade
You were internally filled with violence,
And you sinned;
Therefore I have cast you as profane
From the mountain of God.
And I have destroyed you, O covering cherub,
From the midst of the stones of fire.
Sin is and has always been transgression of the law
The law is in Heaven ... else how did Satan sin?
1st John 3:4
Where there is no law there is no transgression
Before Sinai
Cain murdered Able .... how was this known to be wrong (sin transgression thou shalt not murder) if not for the law being known.
Genesis 9:6 - (God speaking to Noah)
6 Whoever sheds the blood of man,
by man his blood will be shed;
Genesis 13:13 …..”The men of Sodom were wicked and sinners before the Lord exceedingly.”
2nd Peter 2:7-8 …..”And delivered just Lot, vexed with the filthy conversation of the wicked; for that righteous man dwelling among them, in seeing and hearing, vexed his righteous soul from day to day with their unlawful deeds.”
Genesis 15:16 …..”But in the fourth generation they shall come hither again; for the iniquity of the Amorites is not yet full.
How could the men of Sodom be wicked and sinners if there was no law in place? And how could the Amorites be guilty of iniquity if there was no law? And for the most clear cut Bible verse, have another look at 2nd Peter 2:7-8 above. It says that the people of Sodom did UNLAWFUL deeds. Now how can someone be UNlawful where there is no law? There had to have been a law in place for the people to obey, and that law was the Ten Commandments.
Genesis 26:5 …..”Because that Abraham obeyed My voice, and kept My charge, My commandments, My statutes and My laws.”….. What did Abraham do (before Sinai)? He kept GOD’s commandments.
Matthew 5:18
"For truly I say to you, until heaven and earth pass away, not the smallest letter or stroke shall pass from the Law until all is accomplished.
Does not say except the 4th commandment that is only for the Jews.
Jesus kept the Sabbath .... all the apostles kept the Sabbath.
Some argue ... Jesus was a Jew .... more importantly, Jesus is God!
John 10:30
I and the Father are one."
John 14
9 Jesus replied, “Philip, I have been with you all this time, and still you do not know Me? Anyone who has seen Me has seen the Father. How can you say, ‘Show us the Father’? 10 Do you not believe that I am in the Father and the Father is in Me? The words I say to you, I do not speak on My own. Instead, it is the Father dwelling in Me, performing His works.…
We are called to walk in the footsteps of Jesus.
Where in the Bible does either Jesus or any of the apostles say it is not necessary to keep the 7th day Sabbath? If it was not necessary to keep it ... then why did they keep it?
Even at His death (Jesus) the 7th day Sabbath was kept. If the 7th day Sabbath was nailed to the cross .... why did was the 7th day Sabbath kept even at Jesus' death? Because they were Jews? Were they not followers of Christ .... yes they were and because Jesus kept the Sabbath so did they.
The 7th day Sabbath is different from other "sabbaths" that were kept in regard to ceremonies, ordinances, festivals related to the sacrificial system.
Colossians 2:14
Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross;
Christ fulfilled the obligations of the ceremonial law by becoming the Lamb slain for the sins of the world. He fulfilled the obligation of the law of Ten Commandments by His perfect obedience to its precepts. After His death, the law of ceremonies were discontinued (took about 40 years before completely ceasing, but they did) because it foreshadowed the cross, but the law of Ten Commandments did not change, nor was it done away with. The same law (10 Commandments) is still to be found in the New Testament and those who follow Christ.
Matthew 5:18
"For truly I say to you, until heaven and earth pass away, not the smallest letter or stroke shall pass from the Law until all is accomplished.
All has not yet been accomplished ... the Law stands.
The Law stands ... but because Jesus kept the Law ... through His blood believers in Him will be saved from condemnation of the Law .... that is something quite different than claiming the Law was/is abolished or done away with.
Without the law there would be no knowledge of sin.
When all is done .... those with the Lord will be in perfect harmony with the Law ... the Law does and will stand/exist but the breaking of it (sin) will be gone (we will be changed) with the final outcome being eternal life with God living in perfect harmony with Him and according to and within His Law. We will be given a new nature ... a nature without sin (transgression of the law) and this will be for eternity. AMEN!
Will sabbath be kept in heaven, yes ... all of Gods laws will be kept, naturally.
So, in the meantime, our sin is made known to us (by the law) and with the help of the Holy Spirit He helps us to overcome ... and we stumble at times ... it is a life-long process util all is done.
