Throughout history, calendars have changed - different numbers of days in a year, days in a month or months in a year. But one thing has remained the same as long as we can look back: the 7-day week.

"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." Genesis 2:2-3

"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. " (Exodus 20:8-10a)

Now, in my familly, the issue isn't that we work all the time and never take a Sabbath rest. It's more that we should only take one day to rest - not the whole weekend. We enjoy our rest! Since I was on a retreat with women from church yesterday, was that my rest day? But my hubby worked all day taking care of kids and preparing for teaching at church today, so he definitely needs a rest today. It can be hard to work when others are resting, but when that's what God asks, I need to obey!
