"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. 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. (Gen 2:2-3)
If God Himself rested on the seventh day and we are created in His image and likeness, then surely we need to do likewise? God declares this Sabbath day as holy, set apart from the other six days. So this day is all about being set apart to be a holy people. It is not surprising then that this seventh day has been and is such a major stumbling stone to people in the mainline Christian denominations who have taken on the lie that the Torah is done away with and has been replaced by Grace. The enemy, the Anti-Christ supports those who are anti-Torah as he is the Lawless One, the 'Torahless' One! We who are call Christians, the followers of Messiah are meant to be 'called out', ecclesia from the world. Set apart to be holy and righteous under a Holy God who hates sin but loves the sinner.
Psa 119:29 Keep me from being deceitful, and be kind enough to teach me your Torah.
