Hi SB, I am not against the 7th day as God's Sabbath Day, because it is His Sabbath day! According to His Word... God work 6 days then Rest on the 7th.
But in Hebrews 3&4, is about God's people Sabbath Day/Rest (the day we enter into God's Sabbath Rest just as He did on the 7th day in creation week)
In Hebrews there are two different rests being referred to, Christ rest and the seventh day Sabbath rest.
Hebrews 4:10
For he who has entered His rest (gospel rest)
has himself also ceased from his works (Sabbath rest) as God did from His. (on the seventh day Hebrews 4:4, Exodus 20:10, Genesis 2:1-3)
God is not a day (the Sabbath day) He gives us rests and blesses us when we obey Him. Isaiah 58:13, Revelation 22:14
Hebrews 4:3..."we who believe enter that Rest"...(here it doesnt say we believe only on the 7th day to enter into His Sabbath Rest but rather either we believe or Not determine our Sabbath Rest)
This is referring to the gospel/spiritual rest and belief and obedience are interchangeable....
Hebrews 4: 3
For we who have believed do enter that rest, as He has said:
“So I swore in My wrath,
‘They shall not enter My rest,’ ”
although the works were finished from the foundation of the world.
Hebrews 4:6 Since therefore it remains that some
must enter it,
and those to whom it was first preached did not enter because of disobedience,
What was it that those who it was first preached was disobedient to?
The Sabbath rest....
Ezekiel 20:13
Yet the house of Israel rebelled against Me in the wilderness; they did not walk in My statutes; they despised My judgments, ‘which,
if a man does, he shall live by them’;
and they greatly defiled My Sabbaths. Then I said I would pour out My fury on them in the wilderness, to consume them.
We are not to follow the same path of disobedience:
Hebrews 4:11
Let us therefore be diligent to enter that rest, lest anyone fall according to the same example of disobedience.
Which is why the Sabbath rest (Sabbath keeping) remains (not changed) for the people of God.
Hebrews 4:9 NIV
There remains, then, a Sabbath-rest for the people of God;
Ezekiel 20:20 hallow My Sabbaths, and they will be a sign between Me and you, that you may know that I
am the Lord your God.’
Ezekiel 20:12 Moreover I also gave them My Sabbaths, to be a sign between them and Me, that they might know that I
am the Lord who sanctifies them.
We cannot sanctify ourselves, we do so through the Truth of God's Word John 17:17 all of God's commandments are Truth Psalms 119:151 and unchanging Deut 4:2
