I have encountered statements to the effect that the Sabbath was not actually something prescribed by God for Ancient Israel, but instead something that Ancient Israel adapted from Ancient Near Eastern paganism. Can you help with this?!
“Therefore, let us fear if, while a promise remains of entering His rest, any one of you may seem to have come short of it. For indeed we have had good news preached to us, just as they also; but the word they heard did not profit them, because it was not united by faith in those who heard. For we who have believed enter that rest, just as He has said, ‘AS I SWORE IN MY WRATH, THEY SHALL NOT ENTER MY REST’ [Psalm 95:11], although His works were finished from the foundation of the world. For He has said somewhere concerning the seventh day: ‘AND GOD RESTED ON THE SEVENTH DAY FROM ALL HIS WORKS’ [Genesis 2:2]; and again in this passage, ‘THEY SHALL NOT ENTER MY REST’ [Psalm 95:11]. Therefore, since it remains for some to enter it, and those who formerly had good news preached to them failed to enter because of disobedience, He again fixes a certain day, ‘Today,’ saying through David after so long a time just as has been said before, ‘TODAY IF YOU HEAR HIS VOICE, DO NOT HARDEN YOUR HEARTS’ [Psalm 95:7-8]. For if Joshua had given them rest, He would not have spoken of another day after that. So there remains a Sabbath rest for the people of God. For the one who has entered His rest has himself also rested from his works, as God did from His” (NASU).
“Therefore no one is to act as your judge in regard to food or drink or in respect to a festival or a new moon or a Sabbath day—things which are a mere shadow of what is to come; but the substance belongs to Messiah. Let no one keep defrauding you of your prize by delighting in self-abasement and the worship of the angels, taking his stand on visions he has seen, inflated without cause by his fleshly mind, and not holding fast to the head, from whom the entire body, being supplied and held together by the joints and ligaments, grows with a growth which is from God. If you have died with Messiah to the elementary principles of the world, why, as if you were living in the world, do you submit yourself to decrees, such as, ‘Do not handle, do not taste, do not touch!’ (which all refer to things destined to perish with use)—in accordance with the commandments and teachings of men? These are matters which have, to be sure, the appearance of wisdom in self-made religion and self-abasement and severe treatment of the body, but are of no value against fleshly indulgence” (NASU).
“However at that time, when you did not know God, you were slaves to those which by nature are no gods. But now that you have come to know God, or rather to be known by God, how is it that you turn back again to the weak and worthless elemental things, to which you desire to be enslaved all over again? You observe days and months and seasons and years. I fear for you, that perhaps I have labored over you in vain” (NASU).
