Well, a number of attributes can be given to God based on natural revelation. For example, the fact that the sun rises every morning, that every time you drop something it goes to the ground, that every time you mix 1 mole of sodium and one mole of chloride you get table salt, the existence of mathematics and the laws of logic, laws of physics and chemistry etc.
All these show God to be a God of order and control whose power, by necessity, extends throughout the universe.
