Sabbath rest should thank God for our work. If we have work to do, God has given it—even jobs we do not like. He has also provided the strength, wisdom, endurance, and creativity to complete any work that is behind us. (He has also given others to help us with our work!)
The beginning of Genesis is rich enough and deep enough to repay a lifetime of rereadings. I noticed something recently in these early chapters which cannot be original to me but which I had not seen before.
Here is the end of Genesis 1 and the beginning of Genesis 2.
And God saw everything that he had made, and behold, it was very good. And there was evening and there was morning, the sixth day. Thus the heavens and the earth were finished, and all the host of them. 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. (Genesis 1:31–2:3)
What I hadn’t seen before is this: The heavens and the earth were finished on the sixth day, but God finished his work on the seventh.
On the seventh day, God “rested from all his work that he had done in creation.”
