The Sabbath of the New Covenant

The Sabbath is the commemoration day of the Creator, which originated from the day God rested after He created all things in the very beginning. This is why we remember God the Creator on this day. In Genesis 1, God carried out the work of creation for six days, and in Genesis 2, God put a special meaning in the Sabbath by resting on the seventh day after completing the work of creation.

Thus the heavens and the earth were completed in all their vast array. By the seventh day God had finished the work he had been doing; so on the seventh day he rested from all his work. And God blessed the seventh day and made it holy, because on it he rested from all the work of creating that he had done.
Ge 2:1–3

The Sabbath, which was established at the Creation, was codified in the time of Moses. God explained in detail about the Sabbath when declaring the Ten Commandments—the law of the Old Testament.

“Remember the Sabbath day by keeping it holy. Six days you shall labor and do all your work, but the seventh day is a Sabbath to the LORD your God. On it you shall not do any work, neither you, nor your son or daughter, nor your manservant or maidservant, nor your animals, nor the alien within your gates. For in six days the LORD made the heavens and the earth, the sea, and all that is in them, but he rested on the seventh day. Therefore, the LORD blessed the Sabbath day and made it holy.”
Ex 20:8–11

God Himself proclaimed, “Remember the Sabbath day by keeping it holy.” The Sabbath is a command established by God, not a man-made rule devised by Satan. God commanded His people to remember the Sabbath day by keeping it holy and gave them His laws, decrees, and regulations.
