Genesis

 Note that God (Yahweh was and is regarded by his followers as omnipotent.) spend 6 days creating the world. Does this indicate that God the Creator was exhausted after each day's work, and needed to rest and regain his strength before going forth the next day. One could argue that God's so creating could reveal his limited power, strength and endurance--in essence arguing that his taking 6 days to create the world is a manifestation of his not being omnipotent.

That would not be my conclusion, though I think Fate is omnipotent, but not the Father and the Mother, though they are extremely powerful. I would suggest that De spent 6 days creating the world, because oe likes to create beauty and then have a chance and time to savor and enjoy it before dashing off to a replacement undertaking. This is how I would explain that God took a few days to create the world.

I also believe that God was setting a self-conscious example for how humans are to create and work, doing what they can each day, resting that night, coming back and doing some more each consecutive day, while resting on the 7th day. Since moderation is wisdom and love, God is demonstrating from early on by example how humans are to live, operate and proceed.
