Well. it is okay if we don't agree on everything. If you do not recognize the typology of Christ in the Sabbath you may not see Him as the Tree of Life in the Garden, the Lamb of sacrifice in the Law, the Pattern of the entire Tabernacle of Moses and etc)- none of this would affect your salvation so it is of lessor importance. To me enter the rest of Christ is no waste of time, the priesthood (believers) can and do work: God fore-ordained works for us but they are His works not ours - like Jesus in His earth walk this is how we are to operate only at the Holy Spirit's leading, only the Father's will and Words, and only in the Holy Spirit's power. One who walks in the Spirit is led of the Spirit and needs no written instruction in pleasing God or walking righteously as the Holy Spirit leads us in all truth.
As far as the commandments- we could never keep them in true spirit or motive and keeping them otherwise was no more than filthy rags and Pharaseeism . As far as redemption- it was always desperately needed and the Law was given to show man's inability to please God. The Law was in fact given to show man his utter helplessness and his total need for salvation. The came and sin was imputed to man:
Rom 5:13 (For until the law sin was in the world: but sin is not imputed when there is no law.
If one recognizes his desperate state (inability to please God in his own strength and effort) then he will lean all the more on the Spirit of God . While there are multiple scriptures that declare a believer (born again son of God) to be free from the Law there is not one saying he should break the Law. The one and only difference is this: those who try to walk the Law will fail, those who by faith walk in the Spirit will not seek to fulfill the lusts of the flesh and will always walk in a way pleasing to God. That way is love against which there is no law (or Law) and love does not transgress. Only Christ in us, only the power of the Holy Spirit of God can lead us in true righteousness.

Rom 7:5 For when we were in the flesh, the motions of sins, which were by the law, did work in our members to bring forth fruit unto death.
Rom 7:6 But now we are delivered from the law, that being dead wherein we were held; that we should serve in newness of spirit, and not in the oldness of the letter.
Rom 7:7 What shall we say then? Is the law sin? God forbid. Nay, I had not known sin, but by the law: for I had not known lust, except the law had said, Thou shalt not covet.
Rom 7:8 But sin, taking occasion by the commandment, wrought in me all manner of concupiscence. For without the law sin was dead.
Rom 7:9 For I was alive without the law once: but when the commandment came, sin revived, and I died.
Rom 7:10 And the commandment, which was ordained to life, I found to be unto death.
Rom 7:11 For sin, taking occasion by the commandment, deceived me, and by it slew me.
Rom 7:12 Wherefore the law is holy, and the commandment holy, and just, and good.
Rom 7:13 Was then that which is good made death unto me? God forbid. But sin, that it might appear sin, working death in me by that which is good; that sin by the commandment might become exceeding sinful.
Rom 7:14 For we know that the law is spiritual: but I am carnal, sold under sin.
Rom 7:15 For that which I do I allow not: for what I would, that do I not; but what I hate, that do I.
Rom 7:16 If then I do that which I would not, I consent unto the law that it is good.
Rom 7:17 Now then it is no more I that do it, but sin that dwelleth in me.
Rom 7:18 For I know that in me (that is, in my flesh,) dwelleth no good thing: for to will is present with me; but how to perform that which is good I find not.
Rom 7:19 For the good that I would I do not: but the evil which I would not, that I do.
Rom 7:20 Now if I do that I would not, it is no more I that do it, but sin that dwelleth in me.
Rom 7:21 I find then a law, that, when I would do good, evil is present with me.
Rom 7:22 For I delight in the law of God after the inward man:
Rom 7:23 But I see another law in my members, warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members.
Rom 7:24 O wretched man that I am! who shall deliver me from the body of this death?
Rom 7:25 I thank God through Jesus Christ our Lord. So then with the mind I myself serve the law of God; but with the flesh the law of sin.
Gal 4:1 Now I say, That the heir, as long as he is a child, differeth nothing from a servant, though he be lord of all;
Gal 4:2 But is under tutors and governors until the time appointed of the father.
Gal 4:3 Even so we, when we were children, were in bondage under the elements of the world:
Gal 4:4 But when the fulness of the time was come, God sent forth his Son, made of a woman, made under the law,
Gal 4:5 To redeem them that were under the law, that we might receive the adoption of sons.
Gal 4:6 And because ye are sons, God hath sent forth the Spirit of his Son into your hearts, crying, Abba, Father.
Gal 4:7 Wherefore thou art no more a servant, but a son; and if a son, then an heir of God through Christ.
As far as the insistence of some on separation of Ceremonial Law and the Ten Commandment given Moses : There is no more direct biblical support or verse(s) to substantiate a lack of Christ giving us freedom from trying to fulfill the commandments on our own than there is for us to still slay goats in sacrifice.
Note in the following scriptures are not addressing Ceremonial Law but moral thought and actions which are clearly related to the Ten Commandments of the Law of Moses:
Red Emphasis Mine
Gal 5:18 But if ye be led of the Spirit, ye are not under the law.
Gal 5:19 Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness,
Gal 5:20 Idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies,
Gal 5:21 Envyings, murders, drunkenness, revellings, and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall not inherit the kingdom of God.
Gal 5:22 But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith,
Gal 5:23 Meekness, temperance: against such there is no law.
Gal 5:24 And they that are Christ's have crucified the flesh with the affections and lusts.
Gal 5:25 If we live in the Spirit, let us also walk in the Spirit.
Anyway, we many never agree on everything but I enjoy a good discussion on the Word my friend. As iron sharpens iron let us continue to provoke one another to a (Spirit led) study of the Word.
Much love in Christ,
your brother Larry.
