Hashem created the world with speech. Hashem continues to create the world with speech. Speech is effortless in comparison with action; it follows then that Hashem did not have to work too hard to create the universe.
So why dies he get so tired? Why does he need to rest every weekend? And how does the world continue to exist if the creator is resting?
It's not hard to talk to someone who shares your knowledge, background, culture, and expertise. It is, however, very difficult to talk to someone who does not share your perspective and with whom you have nothing in common.
For the first six days of creation, as well as every week day, Hashem works very hard. He is talking to a realty that does not understand him. He must limit how much he revels of himself. He is like the great scientist trying to explain to a five year old child a theory far too complex for most adults. No wonder he gets so tired.
Then, finally, on the seventh day, as well as every Shabbat, he stops working hard. He is like the professor that was suddenly transported to a room full of PhD’s. There is no need to hold anything back. There is just a flow of revelation.
That is why Shabbat is a spiritual day. You may have to work harder to understand what Hashem is telling you, but it's all there. He isn’t hiding anything. All you need to do is tune in.
