Two considerations, and even more if you remember everybody else's doctrine of divisions in this while world.
But these two for now, is Sabbath and the law ended, or does it continue in faith ?
In the Levitical priesthood, the Sabbath was important, but there was a change of both the priesthood and the High Priest and the law.
The law made nothing perfect ( Sabbath keeping was while under a curse, it did nothing at all therefore....
Hebrews 7:11 If therefore perfection were by the Levitical priesthood, (for under it the people received the law,) what further need was there that another priest should rise after the order of Melchisedec, and not be called after the order of Aaron?
12 For the priesthood being changed, there is made of necessity a change also of the law.
Hebrews 7:18 For there is verily a disannulling of the commandment going before for the weakness and unprofitableness thereof.
19 For the law made nothing perfect, but the bringing in of a better hope did; by the which we draw nigh unto God.
We understand the bringing in of the better hope made all perfect ( Jesus did not teach at all about the Sabbath to be included to be doing perfectly, but even resisted against Israel who defended the Sabbath and Jesus not keeping it)
But this High Priest became us ( we are in the priesthood) to be holy, by being harmless, undefiled...
Hebrews 7:26 For such an high priest became us, who is holy, harmless, undefiled, separate from sinners, and made higher than the heavens;
The new covenant occurs when the old one decays, and vanishes away, it is when our sins are forgiven through the faith of Christ..
Hebrews 8:12 For I will be merciful to their unrighteousness, and their sins and their iniquities will I remember no more.
13 In that he saith, A new covenant, he hath made the first old. Now that which decayeth and waxeth old is ready to vanish away.
The first covenant had this fault, it made no conscience perfect.
Now the spotless blood of Christ purges the ( dead) conscience to serve the LIVING GOD..
Hebrews 9:9 Which was a figure for the time then present, in which were offered both gifts and sacrifices, that could not make him that did the service perfect, as pertaining to the conscience;
Hebrews 9:13 For if the blood of bulls and of goats, and the ashes of an heifer sprinkling the unclean, sanctifieth to the purifying of the flesh:
14 How much more shall the blood of Christ, who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God?
Then the drawback again, the comers never could be perfect, their conscience still remembers sins, and still had evil conscience therefore.
Then the sacrifice of Christ perfects forever in sanctification, and all goes into the heart, as the heart has a good conscience now..
Hebrews 10:1 For the law having a shadow of good things to come, and not the very image of the things, can never with those sacrifices which they offered year by year continually make the comers thereunto perfect.
2 For then would they not have ceased to be offered? because that the worshippers once purged should have had no more conscience of sins.
3 But in those sacrifices there is a remembrance again made of sins every year.
Hebrews 10:14 For by one offering he hath perfected for ever them that are sanctified.
15 Whereof the Holy Ghost also is a witness to us: for after that he had said before,
16 This is the covenant that I will make with them after those days, saith the Lord, I will put my laws into their hearts, and in their minds will I write them;
Now we draw near to God with that true heart, it is the faith, and our hearts are sprinkled from the evil conscience, and washed with pure water ( by the Word of Christ in our heart)..
Hebrews 10:22 Let us draw near with a true heart in full assurance of faith, having our hearts sprinkled from an evil conscience, and our bodies washed with pure water.
23 Let us hold fast the profession of our faith without wavering; (for he is faithful that promised
This is the difference between the ordinances of men, and the ordinances of Heaven, it is now written in the heart which is conscience ( that is the Holy Ghost) and our conscience bears witness, and the END OF THE COMMANDMENTS IS CHARITY OUT OF A PURE HEART AND OF A GOOD CONSCIENCE, BUT THEY GOING ABOUT TO ESTABLISH THEIR OWN RIGHTEOUSNESS, HAVE NOT SUBMITTED THEMSELVES UNTO THE RIGHTEOUSNESS OF GOD, FOR CHRIST IS THE END OF THE LAW FOR EVERYONE THAT BELIEVES....
Romans 2:15 Which shew the work of the law written in their hearts, their conscience also bearing witness, and their thoughts the mean while accusing or else excusing one another
1 Timothy 1:5 Now the end of the commandment is charity out of a pure heart, and of a good conscience, and of faith unfeigned:
Romans 10:3 For they being ignorant of God's righteousness, and going about to establish their own righteousness, have not submitted themselves unto the righteousness of God.
4 For Christ is the end of the law for righteousness to every one that believeth.
Man now believes with that heart and conscience, to righteousness ( all that Christ did, not the Sabbath, or the law, but laying His life down and the kindness of God and longsuffering, all are not of the law at all) But Israel polluted the Sabbaths, and worshipped Idols, and God gave them statutes not good, and judgments whereby they do not live ( which is the love of God in them/that good conscience/ the Holy Spirit) nobody lives by Sabbaths, they live by laying their life down for others , just as baptism is the answer of a good conscience to God by the resurrection of Jesus Christ ( now the Sabbath keepers can try to answer how their rule keeping is the Gospel of Jesus Christ)..
Ezekiel 20:24 Because they had not executed my judgments, but had despised my statutes, and had polluted my sabbaths, and their eyes were after their fathers' idols.
25 Wherefore I gave them also statutes that were not good, and judgments whereby they should not live;
Romans 10:9 That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.
10 For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.
1 Peter 3:21 The like figure whereunto even baptism doth also now save us (not the putting away of the filth of the flesh, but the answer of a good conscience toward God,) by the resurrection of Jesus Christ:
