Wisdom is the recovery of innocence at the far end of experience.
In my experience, those who make the most theatrical display of demanding 'proof' of God are also those least willing to undertake the specific kinds of mental and spiritual discipline that all the great religious traditions say are required to find God. If one is left unsatisfied by the logical arguments for belief in God, and instead insists upon some 'experimental' or 'empirical' demonstration, then one ought to be willing to attempt the sort of investigations necessary to achieve any sort of real certainty regarding a reality that is nothing less than the infinite coincidence of absolute being, consciousness, and bliss. In short, one must pray: not fitfully, not simply in the manner of a suppliant seeking aid or of a penitent seeking absolution but also according to the disciplines of infused contemplation, with real constancy of will and a patient openness to grace, suffering states of both dereliction and ecstasy with the equanimity of faith, hoping but not presuming, so as to find whether the spiritual journey, when followed in earnest, can disclose its own truthfulness and conduct one into communion with a dimension of reality beyond the ontological indigence of the physical. No one is obliged to make such an effort; but, unless one does, any demands one might make for evidence of the reality of God can safely be dismissed as disingenuous, and any arguments against belief in God that one might have the temerity to make to others can safely be ignored as vacuous.
God's pleasure--the beauty creation possesses in his regard--underlies the distinct being of creation, and so beauty is the first and truest word concerning all that appears within being; beauty is the showing of what is; God looked upon what he had wrought and saw that it was good.
