The divine revelation of God or the being of God is famously understood from the Ontological argument by St. Anselm at the beginning of the 12th-century, who stated that "God is a being greater than which nothing else can be conceived or imagined". This concept of the existence of God is not based on the observation of nature or science, but on an analysis of the concept of God. A man who would deny that a triangle contains 180° simply does not understand the meaning of a triangle. Someone who denies the existence of God does not grasp the concept of God.
God is a being greater than which nothing else can be conceived or imagined. If God could be conceived not to exist, it would only be possible because of man's ability to reason and to conceive of something greater than God. The idea then would be that something has come from nothing, and for something to come from nothing means that nothing exists.
If we do not demonstrate the existence of God through a rational argument by valid reasoning, then we must accept God's existence solely on scriptural authority where we presuppose the existence of God. The most important question is not, "Is there a God?" But the important question is, "What is God?" This returns us to the description of biblical thinking where, "God is a being greater than which nothing else can be conceived or imagined".
Can you reason the existence of God, or do you just presuppose that He exists? These are wonderful exercises of the mind for one who has been transformed by the renewing of his mind. The concept of the being of God is not only refreshing, but it is compelling.
