Ex 31:13 “Speak also to the children of Israel, saying: ‘Surely My Sabbaths you shall keep, for it is a sign between Me and you throughout your generations, that you may know that I am the Lord who sanctifies you. 14 You shall keep the Sabbath, therefore, for it is holy to you. Everyone who profanes it shall surely be put to death; for whoever does any work on it, that person shall be cut off from among his people.
Ez 20:12 Moreover I also gave them My Sabbaths, to be a sign between them and Me, that they might know that I am the Lord who sanctifies them. ... 19 I am the Lord your God: Walk in My statutes, keep My judgments, and do them; 20 hallow My Sabbaths, and they will be a sign between Me and you, that you may know that I am the Lord your God.’
Isa 56:1 Thus saith the Lord, 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; ... 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. 8 The Lord God, which gathereth the outcasts of Israel saith, Yet will I gather others to him, beside those that are gathered unto him.
Circumcision is a command regarding one of the covenants, but the Sabbath is His sign, His mark that distinguishes between His people and the people of the world as His worship is never to be mixed with the worship practices of the world.
2Kings 17: 7 For so it was that the children of Israel had sinned against the Lord their God, who had brought them up out of the land of Egypt, from under the hand of Pharaoh king of Egypt; and they had feared other gods, 8 and had walked in the statutes of the nations whom the Lord had cast out from before the children of Israel, and of the kings of Israel, which they had made. 9 Also the children of Israel secretly did against the Lord their God things that were not right, ... 34 To this day they continue practicing the former rituals; they do not fear the Lord, nor do they follow their statutes or their ordinances, or the law and commandment which the Lord had commanded, ...
Ecc 12:9 And moreover, because the Preacher was wise, he still taught the people knowledge; yes, he pondered and sought out and set in order many proverbs. 10 The Preacher sought to find acceptable words; and what was written was upright—words of truth. 11 The words of the wise are like goads, and the words of scholars[b] are like well-driven nails, given by one Shepherd. 12 And further, my son, be admonished by these. Of making many books there is no end, and much study is wearisome to the flesh. 13 Let us hear the conclusion of the whole matter:
Fear God and keep His commandments,
For this is the duty of all mankind.
14 For God will bring every work into judgment,
Including every secret thing,
Whether good or evil. Prov 14:12 & 16:25 "There is a way that seems right to a man, but its end is the way of death."
So one must ask themselves, whose eyes am I right in, God or man? Do I follow the precepts of men or do I cling to the precepts of God? Which path, which way do I choose?
Dt 30:19 I call heaven and earth as witnesses today against you, that I have set before you life and death, blessing and cursing; therefore choose life, that both you and your descendants may live; 20 that you may love the Lord your God, that you may obey His voice, and that you may cling to Him, for He is your life and the length of your days
Dt 32:46 and he said to them: “Set your hearts on all the words which I testify among you today, which you shall command your children to be careful to observe—all the words of this law. 47 For it is not a futile thing for you, because it is your life,"
Dt 10:12 what does the Lord your God require of you, but to fear the Lord your God, to walk in all His ways and to love Him, to serve the Lord your God with all your heart and with all your soul, 13 and to keep the commandments of the Lord and His statutes which I command you today for your good
It has always been about the heart. He tests His children o see whether or not it is in their heart to obey Him (Dt 8:2-6). The Dt 13 test, which the Pharisees and scribes consistently used against Messiah is our guide in determining the false prophets and preachers.
Dt 13:1 “If there arises among you a prophet or a dreamer of dreams, and he gives you a sign or a wonder, 2 and the sign or the wonder comes to pass, of which he spoke to you, saying, ‘Let us go after other gods’ (false ways) —which you have not known—‘and let us serve them,’ (serve in that false way) 3 you shall not listen to the words of that prophet or that dreamer of dreams, for the Lord your God is testing you to know whether you love the Lord your God with all your heart and with all your soul. ... 17 So none of the accursed things shall remain in your hand, that the Lord may turn from the fierceness of His anger and show you mercy, have compassion on you and multiply you, just as He swore to your fathers, 18 because you have listened to the voice of the Lord your God, to keep all His commandments which I command you today, to do what is right in the eyes of the Lord your God.
Rev 22:12 “And behold, I am coming quickly, and My reward is with Me, to give to every one according to his work. 13 I am the Alpha and the Omega, the Beginning and the End, the First and the Last.” 14 Blessed are those who do His commandments, that they may have the right to the tree of life, and may enter through the gates into the city. 15 But outside are dogs and sorcerers and sexually immoral and murderers and idolaters, and whoever loves and practices a lie (falsehood, false ways).
2Thess 2:7 For the mystery of lawlessness is already at work; only he who now restrains will do so until he is taken out of the way. 8 And then the lawless one will be revealed, whom the Lord will consume with the breath of His mouth and destroy with the brightness of His coming. 9 The coming of the lawless one is according to the working of Satan, with all power, signs, and lying wonders, 10 and with all unrighteous deception among those who perish, because they did not receive the love of the truth, that they might be saved. 11 And for this reason God will send them strong delusion, that they should believe the lie, 12 that they all may be condemned who did not believe the truth but had pleasure in unrighteousness.
Unrighteousness: doing what is right in one's own eyes rather than what is right in the eyes of God.
Futility: Doing what the Chosen People were COMMANDED to do when it is NOT a 'requirement'.
Jesus answered, “The work of God is this: to believe in the one he has sent.”
