Belief and disbelief in GOD

Let us first consider the disbelief in the existence of God: if there is no God and if the world appeared by itself, this means that it appeared by chance.

If we consider the nature of "chance" itself, we observe that it always describes an event that has no preconceived cause. In any case, it cannot be associated with a planned event. Again, if an event is not planned, there can be no purpose, because everything that has a purpose is planned, whether the planning is conscious (i.e., based on intellectual judgment) or merely instinctive. To summarize, if the world came into being by chance, it is a blind and lawless world. Indeed, the word "chance" itself implies the absence of law. 

So, if the world is inherently lawless, and if everything born of it is also inherently lawless, then the articulation of any law by human beings, whether scientific, ethical, political, or economic, is a violation of human nature and the nature of the world itself. But human beings cannot exist without law. 

From the other perspective, that is, the affirmation of faith in the existence of God, if we believe that God exists and that He created the world, this means that the world appeared according to a planned creation, that it operates according to a system of laws, and that it evolves toward a purpose. In other words, planning, purpose, and laws are inherent in the very constitution of the world. This, in turn, provides the basis for every branch of human law—ethical, political, economic, and so on.
