Being and non-being are like the sun and its shadow.
Being and non-being are like the sun and its shadow. When a body is turned to the sun, it casts a shadow. What is a shadow? The shadow has not been created by anything; it consists simply of the sun not shining in a given place because of the existence of an obstacle; it has no source or origin of its own. Things have a real existence by virtue of having been created without reference to things other than them; in this sense, they are not evil.
For a worldview derived from belief in God, the world is equivalent to good. Everything is inherently good; if it is evil, it is so only in a relative sense and in connection with things other than itself .The existence of every thing is unreal for other than it self, and untouched by creation. The malarial mosquito is not evil in itself. If it is described as such, it is because it is harmful to man and causes disease.
That which is created is the existence of a thing in and of itself, which is a true existence; speculative or conditional existence has no place in the order of being and is not real. We cannot, therefore, ask why God has created relative or conditional existence. Conditional or abstract entities are inseparable from the real entities that give rise to them; they are their inevitable concomitants and do not partake of their being. One cannot then speak of conditional entities having been created.
That which is real must necessarily derive its being from the Creator. Only those things and attributes are real that exist outside the mind. Relative attributes are created by the mind and have no existence outside it so one cannot go looking for the creator. Furthermore, that which has the potential to exist is the world as a whole, with all the objects it contains and the attributes that are inseparable from it; the world represents an indivisible unit.
From the vantage point of God's wisdom, either the world must exist on the pattern that is peculiar to it, or it cannot exist at all. A world without order or lacking the principle of causality, a world where good and evil were not separate from each other, would be an impossibility and a fantasy. It is not possible to suppose that one part of the world should exist and another should not. Creation is a whole, like the form and figure of man, and its parts are inseparable from each other.
