Perhaps not as clear as you think.
So how specifically do you observe the Sabbath?
I ~observe the Sabbath~ in the Scriptures revealed in, through, and by Jesus Christ "the Son of Man Who keeps the Sabbath ... The Man that does this ... that CLAIMS the Sabbath, lays HOLD on it (the Son of Man Lord of the Sabbath), that keeps and guards the Sabbath from being polluted and whose hand protects it from evil being done to it."
Says the Son of Man concerning Himself in the same Scripture, "The LORD has utterly separated Me from the people”. The same Scripture, again, says of Him, “the Son of the stranger” was He among the people, therefore, “He Joined Himself to the LORD”! Being joined to the LORD the Son of Man shall “keep judgment and do justice”, thus: “When ye come to appear before Me, who hath required this at your hand, to tread my courts? Bring no more vain oblations; insense is an abomination unto Me; the new moons and sabbaths, the calling of assemblies—I cannot away with! it is iniquity, even the solemn meeting. Your, new moons and your, appointed feasts my, soul hateth; they are a trouble unto Me; I am weary to bear them. And when ye, spread forth your hands, I, will hide mine eyes from you: yea, when ye, make many prayers, I, will not hear you: your hands are full of (…my…) blood.”
That is from the OLD Testament, as you know, DHK!
Now what made you think that I keep the Sabbath? The Sabbath is “the Sabbath OF THE LORD” and has always, been HIS, to keep. Which He did, in Jesus Christ, so that “
Jesus gave them rest … and
that therefore for the People of God keeping of the Sabbath Day’s rest, remains their obligation” -- towards God and his Christ.
Has man ever kept one obligation towards God? Never, except The Son of Man Jesus Christ, who kept every obligation towards God “for man”. That’s why God “made the Sabbath for man”.
I do not keep the Lord’s Day; He is its Keeper and Lord Protector. I only ~observe~ “God thus concerning” the Sabbath “spake” in his Word--- “the Word of God quick and powerful and sharper than a two-edged sword (Old and New Testaments) piercing even to the dividing asunder of soul and spirit (indivisible) and of the joints and marrow (enclosed together)--- the “Word of God Discerner of the thoughts and intents of the heart (indifferent).”
The untrustworthiness of man does not cancel out the faithfulness of God -- of God having kept Word in Christ .
