remember that the scripture says specifically that the sabbaths - all of them - are a shadow, not the substance. and the Substance has been revealed.
therefore it is false to say that His rest is the physical ritual act of sabbath observance, likewise false to call the 7th day itself His rest, just as much as it is false to understand circumcision as the physical act even though the physical act was commanded to a people at a time. the intent of the Law is spiritual not physical: the Law is not of faith.
What Law is not of Faith?
"I am the Lord your God, thou shall have no other god's before me"?
or
"if you sin, take your best goat to a Levite Priest and he will kill the goat and perform ceremoniel "Works of the Law" to atone for your sin"
There are some who understand when the SEED came, the Priesthood and the "works therein" changed as prophesied in the Law and Prophet's. But the sovereignty and judgment of the Most Holy didn't change. Only in the hearts of men.
Is. 56:
1 Thus saith the LORD, (Word which became Flesh) Keep ye judgment, and do justice: for my salvation
is near to come,
and my righteousness to be revealed.
2 Blessed
is the man
that doeth this, and the son of man
that layeth hold on it;
that keepeth the sabbath from polluting it, and
keepeth his hand from doing any evil.
3 Neither let the
son of the stranger, that hath joined himself to the LORD, speak, saying, The LORD hath utterly separated me from his people: neither let the eunuch say, Behold, I
am a dry tree.
4 For thus saith the LORD unto the eunuchs that keep my sabbaths, and choose
the things that please me, and take hold of my covenant;
5 Even unto them will I give in mine house and within my walls a place and
a name better than of sons and of daughters: I will give them an everlasting name, that shall not be cut off.
6 Also the sons of the stranger, that join themselves to the LORD, to serve him, and to love the name of the LORD,
to be his servants,
every one that keepeth the sabbath from polluting it, and taketh hold of my covenant;
7 Even them will I bring to my holy mountain, and make them joyful in my house of prayer: their burnt offerings and their sacrifices
shall be accepted upon mine altar; for mine house shall be called an house of prayer for all people.
This is how the Word which became Flesh spoke of His Holy Sabbath that He said was made for man.
Is. 58:
13 If thou turn away thy foot from the sabbath,
from doing thy pleasure
on my holy day; and call the sabbath a delight, the holy of the LORD, honourable;
and shalt honour him,
not doing thine own ways, nor finding
thine own pleasure, nor speaking
thine own words:
14 Then shalt thou delight thyself in the LORD; and I will cause thee to ride upon the high places of the earth, and feed thee with the heritage of Jacob thy father: for the mouth of the LORD hath spoken
it.
But of the "Works of the Law" for justification of sins Paul spoke of in Romans and Galatians, this same Word said this:
1 Sam. 15:
22 And Samuel said, Hath the LORD
as great delight in burnt offerings and sacrifices,
as in obeying the voice of the LORD?
Behold, to obey is better than sacrifice,
and to hearken than the fat of rams.
23 For rebellion is as the sin of witchcraft, and stubbornness is as iniquity and idolatry. Because thou hast rejected the word of the LORD, he hath also rejected thee from
being king.
Ex. 20:
2 I
am the LORD thy God, (Word which became Flesh) which have brought thee out of the land of Egypt, (Sin) out of the house of bondage. (deception)
3 Thou shalt have no other gods before me.
8 Remember the sabbath day, to keep it holy.
Jer. 6:
16 Thus saith the LORD, Stand ye in the ways, and see, and ask for the old paths, where
is the good way,
and walk therein,
and ye shall find rest for your souls.
But they said,
We will not walk therein.
As it is to this day.
