The God of the Bible is not only a hard-working God but also one who cares deeply for His creations. He set the example for us by creating the universe and all that it contains in six days and then rested on the seventh.
These teachings show us that there is literal time of seven days and nights as well as teaching us that we are to be fruitful, multiplying, filling, ruling, and subduing all that He has given us as well as taking the time for rest.
Gen. 2: 1-2
