If I did not already own a lovely hardback copy of Abraham Joshua Heschel’s God In Search of Man, I’d be desperate to find a copy for my sacred library:

It is the assertion that God is real, independent of our preconceptual awareness, that presents the major difficulty. Subjective awareness is not always an index of truth. What is subjectively true is not necessarily trans-subjectively real. All we have is the awareness of allusions to His concern, intimations of His presence. To speak of His reality is to transcend awareness, to surpass the limits of thinking. It is like springing clear of the ground. Are we intellectually justified in inferring from our awareness a reality that lies beyond it? Are we entitled to rise from the realm of this world to a realm that is beyond this world?

We are often guilty of misunderstanding the nature of an assertion such as “God is.” Such an assertion would constitute a leap if the assertion constituted an addition to our ineffable awareness of God. The truth, however, is that to say “God is” means less than what our immediate awareness contains. The statement “God is” is an understatement.

Thus, the certainty of the realness of God does not come about as a corollary of logical premises, as a leap from the realm of logic to the realm of ontology, from an assumption to a fact. It is, on the contrary, a transition from an immediate apprehension to a thought, from a preconceptual awareness to a definite assurance, from being overwhelmed by the presence of God to an awareness of His existence.

What we attempt to do in the act of reflection is to raise that preconceptual awareness to the level of understanding.
