I see a glaring problem with this.
Hasn't God been having a rest day since the creation of Eve. Wouldn't any change made to the physical world since then by God constitute breaking his own law of the sabbath, of which he is supposed to represent the perfect example?
Some poor guy got stoned for gathering sticks on the sabbath but God redesigns snakes, makes manna fall from the sky, creates rainbows, carves the ten commandments, makes the sun stand still and many other miracles that amount to doing 'work' and its fine?
