What about Exodus 23?
12 “Six days you shall do your work, but on the seventh day you shall rest; that your ox and your donkey may have rest, and the son of your servant woman, and the alien, may be refreshed.
13 “Pay attention to all that I have said to you, and make no mention of the names of other gods, nor let it be heard on your lips.
14 “Three times in the year you shall keep a feast to me."
These are all quotes, in quotes, as if God spoke them, and uses “I” and “me” as you said God does in first person.
Is this not God directly Himself saying rest on the literal 7th day, as He literally created the universe and everything in it in literal 6 days and rested on the 7th?
But like Jesus said, sabbath was created for man, not man for it. The sabbath is there to help us, like all His commandments. God is our provider. Sometimes He uses our work to give us money to provide for us, other times He just does. The sabbath is a rest for us from stressful work, and a reminder to refocus on Him and that He will provide. ChikFilA tests/trusts God in this. It is interesting they serve 1/7 of the time of Mcd and other fast food chains, however their profits are better than all. Using human logic and human pride, their profits should be 1/7th/14% less. But lets say their food and service and business model is better. That would just have them maybe equalize their profits, but no, they actually have better, blessings of God profits. God wants us to refocus on Him, trust He will provide, and relax from stress (which is also not good, but we are human, He created us and know how we work). He knows we need res from stress, we need to relax, and we need to refocus on Him. Jesus tells us to focus on Him daily, by giving us our daily bread. We are short minded/attention humans, the sabbath is a blessing to us, and merciful that He commanded us to, or else we might never remember to refocus on Him.
Our identity is too much in our jobs. “What do you do” is the most asked question when getting to know someone (other than their name or how they are). We identify as a doctor or one who drives a lambo, or who even gives a bunch to charity or a pastor is asked how many members of his church ect… There is nothing wrong with any of those things, but it shouldn’t be our identity, our identity is in God. Our worth is not what job we have, or how successful we are, it is in who God sees us to be. Full of so much worth that He sent His only Son to die for us.
There is no requirement of salvation to honor a sabbath, it is for our good, and God’s glory, when we are brought back to focus on Him and trust Him for being 1/7th as productive as the rest of the world. You ask a guy who has all kinds of money and houses and cars, and he says. “I worked my butt off”. God doesn’t want that, if you are to boast, boast in Him. I trusted God and He has blessed me with comforts of this world, but these are not my treasures.
The sabbath and tithing is basically You saying, I have what I have, because You gave it to me and you provided for me.
