There are varying opinions about how Christians should walk out the sabbath under the new covenant. No matter the opinion, we need to understand the origin and purpose for the sabbath.
“Thus the heavens and the earth were finished, and all the host of them. 2 And on the seventh day God finished his work that he had done, and he rested on the seventh day from all his work that he had done. 3 So God blessed the seventh day and made it holy, because on it God rested from all his work that he had done in creation.” Genesis 2:1-3
