If a supernatural being is to be exempt from natural law, it cannot possess specific, determinate characteristics. These attributes would impose limits and these limits would restrict the capacities of this supernatural being. In this case, a supernatural being would be subject to the causal relationships that mark natural existence, which would disqualify it as a god. Therefore, we must somehow conceive of a being without a specific nature, a being that is indeterminate—a being, in other words, that is nothing in particular. But these characteristics (or, more precisely, lack of characteristics) are incompatible with the notion of existence itself.
