Thank you for asking Yeshua. Having come out of a line of Jews, this topic is especially close to me, now that I understand it.
If you have entered in to the land of rest in full belief and full faith, then you are in the Rest of the Lord

While here, I do righteousness

(Mat 12:12) ...--so that it is lawful on the sabbaths to do good.'
Here's just a few places where we can comprehend what the O.T. shadow type of the seventh day Sabbath pointed forward to mean in it's glory that we now enjoy always;
(Mar 2:24) And the Pharisees said unto him, Behold, why do they on the sabbath day that which is not lawful?
(Mar 2:25) And he said unto them, Did ye never read what David did, when he had need, and was an hungred, he, and they that were with him?
(Mar 2:26) How he entered into the house of God when Abiathar was high priest, and did eat the shewbread, which it is not lawful to eat save for the priests, and gave also to them that were with him?
(Mar 2:27) And he said unto them, The sabbath was made for man, and not man for the sabbath:
(Mar 2:28) so that the Son of man is lord even of the Sabbath.
We aren't to be as those who "didn't believe";
(Heb 3:7) Wherefore, even as the Holy Ghost saith, Today if ye shall hear his voice,
(Heb 3:8) Harden not your hearts, as in the provocation, Like as in the day of the temptation in the wilderness,
(Heb 3:9) Wherewith your fathers tempted
me by proving
me, And saw my works forty years.
(Heb 3:10) Wherefore I was displeased with this generation, And said, They do alway err in their heart: But they did not know my ways;
(Heb 3:11) As I sware in my wrath, They shall not enter into my rest.
(Heb 3:12) Take heed, brethren, lest haply there shall be in any one of you an evil heart of unbelief, in falling away from the living God:
(Heb 3:13) but exhort one another day by day, so long as it is called Today; lest any one of you be hardened by the deceitfulness of sin:
The writer to the Hebrews makes the crucial point, that this has to do with us Christians, and to look at that example of the non-believers;
(Heb 3:14) for we are become partakers of Christ, if we hold fast the beginning of our confidence firm unto the end:
He pretty much says it again;
(Heb 3:16) For who, when they heard, did provoke? nay, did not all they that came out of Egypt by Moses?
(Heb 3:17) And with whom was he displeased forty years? was it not with them that sinned, whose carcases fell in the wilderness?
(Heb 3:18) And to whom sware he that they should not enter into his rest, but to them that were disobedient?
(Heb 3:19) And we see that they were not able to enter in because of unbelief.
He goes into even more in the next chapter, explaining how that we are in that Sabbabth Rest now, because the "type" back then wasn't the "fulfillment", but in light of that past "provocation", that Rest is ours now, as long as we don't "unbelieve";
(Heb 4:1) Let us fear therefore, lest haply, a promise being left of entering into his rest, any one of you should seem to have come short of it.
This is already a long post... I could go on and on about it, because I love the Sabbath Rest in the Holy Land in Christ. But there is enough there to whet one's whistle if one wanted to continue looking at how we now Remain in that Rest through Faith in Christ Jesus, Israel's Messiah, our Lord and our God!
(Heb 4:3) For we which have believed do enter into that rest; even as he hath said...
(Heb 4:9) there doth remain, then, a sabbath rest to the people of God,
(Heb 4:10) for he who did enter into his rest, he also rested from his works, as God from His own.
Though the seventh day "type" is abolished, this True Sabbath Remains and is Eternal and is so much more Glorious. It isn't just "one day" we keep holy now. It is Every Day! In fact, we are Eternally in "The Great and Notable Day of the Lord"! (Acts 2)
Fun huh
