I fully agree with you all! But would like to add something...
Remember that God gave His chosen people the laws because He loved them. Each & every one of them has a spiritual and logical reason why they should be followed.
Spiritually many people do not have the time allotted to REALLY get into Gods word, really come before His throne...setting a day aside for Him helps them to come together with Him again.
Logically...working every day, doing the same thing every day gets monotonous, and can even have bad health implications....
We (my DH, and children) choose to give God Sunday. We are in Church helping, and worshiping from 7AM until 12. At 12:30 we leave church for home...there we have lunch and a discussion about the morning sermon/sunday school classes. We spend the rest of the day with each other...just enjoying each other. We have diinner, then my DH takes the kids to their Missionettes/Royal Rangers classes. I stay home & have "me" time...really it's my time to sing while doing stuff...no one likes my singing voice

. (My DH gets this time to himself on Thursday)...
At the end of Sunday, I feel closer to God, tired, but also refershed for the coming week. I also have had a time to "decompress" from the weekend activities. (Saturday is when we do all of the misc. chores...it's exhausting!)
We don't do this "religiously", we just recognise that when we do this, we're a happier family, and the week goes better for us.
