With respect, we all have faith in something. For some it is in material wealth, for others it is in their own strength and intellect. A small child has faith in its parents, that the mother will always be there to comfort them and the father will protect them. Some have faith in the law, others in justice.
Fowler wrote a book about the stages of faith along the lines of Piaget and Bruner. When I was younger I placed my faith in science and my own intellect. When my father died suddenly I was devasted and neither my cleverness nor my knowledge offered any comfort at all. When my younger sister gave birth to a still born baby I was bereft of words of comfort.
Later, I faced the question, "Where should I place my faith?" I decided that faith placed in finite things is exactly like building the house upon the sands. It was then that I chose the risky decision to place my faith in the infinite and the eternal.
I began to pray.
I still have doubts, but mature faith is quite separate from mere belief. Mature faith is able to absorb doubt and live with it.
