" We depend upon cognitive assent and affective assurances to substantiate the reality of our relationship with God. If we can't "know" or "feel" God, we customarily doubt our relationship with God. But such "knowing" and "feeling" restrict God to the narrow limits of our minds and senses and reduce our relationship with God to the maintenance of such feedback. "
