Wonder, or radical amazement, is a way of going beyond what is given in thing and thought, refusing to take anything for granted, to regard anything as final. It is our honest response to the grandeur and mystery of reality our confrontation with that which transcends the given.
Understanding God is not attained by calling into session all arguments for and against Him, in order to debate whether He is a reality or a figment of the mind. God cannot be sensed as a second thought, as an explanation of the origin of the universe. He is either the first and the last, or just another concept.
In our daily lives we attend primarily to that which the senses are spelling out for us: to what the eyes perceive, to what the fingers touch. Reality to us is thinghood , consisting of substances that occupy space; even God is conceived by most of us as a thing. The result of our thinginess is our blindness to all reality that fails to identify itself as a thing, as a matter of fact.
