True Jesus is our rest but prove from the bible that we no longer need to on the sabbath as God has asked us to.
Heb 4:1 Let us therefore fear, lest, a promise being left us of entering into his rest, any of you should seem to come short of it.
Heb 4:2 For unto us was the gospel preached, as well as unto them: but the word preached did not profit them, not being mixed with faith in them that heard it.
Heb 4:3 For we which have believed do enter into rest, as he said, As I have sworn in my wrath, if they shall enter into my rest: although the works were finished from the foundation of the world.
Heb 4:4 For he spake in a certain place of the seventh day on this wise, And God did rest the seventh day from all his works.
Heb 4:5 And in this place again, If they shall enter into my rest.
Heb 4:6 Seeing therefore it remaineth that some must enter therein, and they to whom it was first preached entered not in because of unbelief:
Heb 4:7 Again, he limiteth a certain day, saying in David, To day, after so long a time; as it is said, To day if ye will hear his voice, harden not your hearts.
Heb 4:8 For if Jesus had given them rest, then would he not afterward have spoken of another day.
Heb 4:9 There remaineth therefore a rest to the people of God.
Heb 4:10 For he that is entered into his rest, he also hath ceased from his own works, as God did from his.
Heb 4:11 Let us labour therefore to enter into that rest, lest any man fall after the same example of unbelief.
You can say this is just talking about finding rest in Jesus but there is too many references to the sabbath day and the rest that God had at creation to ignore.
that's easy enough
6Therefore, just as you have received Christ Jesus as Lord, continue to walk in Him,
7rooted and built up in Him, established in the faith as you were taught, and overflowing with thankfulness.
8See to it that no one takes you captive through philosophy and empty deception, which are based on human tradition and the spiritual forces of the world rather than on Christ.
9For in Christ all the fullness of the Deity dwells in bodily form.
10And you have been made complete in Christ, who is the head over every ruler and authority.
11In Him you were also circumcised, in the putting off of your sinful nature, with the circumcision performed by Christ
b and not by human hands.
12And having been buried with Him in baptism, you were raised with Him through your faith in the power of God, who raised Him from the dead.
13When you were dead in your trespasses and in the uncircumcision of your sinful nature, God made you alive with Christ. He forgave us all our trespasses,
14having canceled the debt ascribed to us in the decrees that stood against us. He took it away, nailing it to the cross!
15And having disarmed the powers and authorities, He made a public spectacle of them, triumphing over them by the cross.
16Therefore let no one judge you by what you eat or drink, or with regard to a feast, a New Moon, or a Sabbath.
17These are a shadow of the things to come, but the body that casts it belongs to Christ.
c 18Do not let anyone who delights in false humility and the worship of angels disqualify you with speculation about what he has seen. Such a person is puffed up without basis by his unspiritual mind.
19He has lost connection to the head, from whom the whole body, supported and knit together by its joints and ligaments, grows as God causes it to grow.
20If you have died with Christ to the spiritual forces of the world, why, as though you still belonged to the world, do you submit to its regulations:
21“Do not handle, do not taste, do not touch!”?
22These will all perish with use, because they are based on human commands and teachings.
23Such restrictions indeed have an appearance of wisdom, with their self-prescribed worship, their false humility, and their harsh treatment of the body; but they are of no value against the indulgence of the flesh.
Colossians 2
I'm sure we can discuss that further. Hebrews has nothing to do with instructions on keeping the Sabbath
the purpose of Hebrews was to exhort Christians in the face of persecution...not exhorting them to keep the Sabbath. you have to understand that it was revolutionary for Jewish people to commit to following Christ and understand that salvation is through Him alone, see Colossians 2 above (and of course many other passages)
it is interesting and yet sad, that so many seem to want to revert to the law, or think they should keep parts of it, and of course the 'Sabbath keeping' is the easiest thing in the world to follow. no effort at all...just change days and declare that you are keeping the Sabbath when nothing we do can earn or keep us saved. all of Christianity is through faith and in that regard, Hebrews is actually a book famous for its examples of faith.
Letter to the Colossians (church at Colossae) by Paul to admonish them as he had heard they were falling into serious error
the New Testament contains nothing at all about how we are to keep the law, parts of the law or special days. Christ is all. He is our High Priest whose sinless blood is on the altar and no more sacrifices are needed and no 'works' on our part
