Heb 4:
Therefore, since
a promise remains of entering His rest, let us fear lest any of you seem to have come short of it. 2 For indeed
the gospel was preached to us as well as to them; but the word which they heard did not profit them, not being mixed with faith in those who heard
it.
The unfaithful unbelieving in Heb 3 and 4 did not enter Canaan. But the solution is not presented as "
more rebellion against the 4th commandment".
We are put on the same level ground in vs 2 - with the
Gospel preached to BOTH groups. (this is not a condemnation of the OT scriptures by a long shot)
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. 4 For He has spoken in a certain place of the seventh day in this way: “And God rested on the seventh day from all His works”; 5 and again in this place: “They shall not enter My rest.”
This is where Paul switched from the rest of Canaan which they did not have for 40 years - to the rest both groups have in choosing belief, choosing obedience rather than rebellion. It is using the "rest" aspect of the Sabbath to make the point.
So we see in Heb 11 many in the OT given as examples of those in the OT who were men of faith, of belief, of obedience. Who did enter that same rest we have today who also choose obedience, faith,
6 Since therefore it remains that some must enter it, and those to whom it was first preached did not enter because of disobedience,
No we see that even today it "remains that SOME" must enter. So then SOME have not chosen belief it remains for them to enter rather than to choose to disobey the Word of God.
7 again He designates a certain day, saying in David, “Today,” after such a long time, as it has been said:
“Today, if you will hear His voice,
Do not harden your hearts.”
He points us to the REST that was called for at the time of David.
8 For if Joshua had given them rest, then He would not afterward have spoken of another day. 9 There remains therefore a rest for the people of God.
The Sabbath is a good symbol of that rest because the Sabbath remains. Unlike the shadows of sacrifices and offerings that do not remain Heb 10:4-12 "He takes away the first to establish the second" -- the Sabbath remains and is a good symbol for the rest that remains.
10 For he who has entered His rest has himself also ceased from his works as God did from His.
11 Let us therefore be diligent to enter that rest, lest anyone fall according to the same example of disobedience.
The idea that more disobedience against a command of God is what is needed as the remedy - the text specifically tells us to flee disobedience.
12 For the word of God is living and powerful, and sharper than any two-edged sword, piercing even to the division of soul and spirit, and of joints and marrow, and is a discerner of the thoughts and intents of the heart. 13 And there is no creature hidden from His sight, but all things are naked and open to the eyes of Him to whom we must give account.
14 Seeing then that we have a great High Priest who has passed through the heavens, Jesus the Son of God, let us hold fast our confession. 15 For we do not have a High Priest who cannot sympathize with our weaknesses, but was in all points tempted as we are, yet without sin. 16 Let us therefore come boldly to the throne of grace, that we may obtain mercy and find grace to help in time of need.
Heb 3 starts out telling us that scripture - the OT is "THE Holy Spirit says"
Heb 4 ends by reminding us that "the WORD of GOD" is powerful and is to be obeyed. Rebellion against it - is not the solution.
