Thus the heavens and the earth were completed in all their vast array.
2 By the seventh day God had finished the work he had been doing; so on the seventh day he rested from all his work. 3 Then 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 2:1-2
Six days to create the universe, and one day to rest. God didn’t need six days to create everything, nor did he need to rest. He didn’t rest because He was tired or fatigued; He rested because He was pleased with what He had created. Everything He created continues on to this day.
His resting was a great example for us. We work hard for six days and rest on the seventh. We need that day to reflect and recover. The seventh day of rest significantly contrasts and complement the six days of work. You also see that throughout the Old Testament where God commands the seventh year for the land to rest.
I think we need to rediscover what it means to rest. Likewise, many of us need to rediscover good old-fashioned hard work.
