This chapter introduces the problem of divine hiddenness, largely as a point of departure. Within theology and philosophy, this phenomenological reality has become the experiential center of a debate about the so-called problem of divine hiddenness. When a positive intellectual content is associated with a faith-state, it gets invincibly stamped in upon belief, and this explains the passionate loyalty of religious persons everywhere to the minutest details of their so widely differing creeds. Researchers in cognitive science of religion differ on how and why religious beliefs arose within human communities, but the consensus is that such belief comes easily and naturally to the sort of cognitive architecture that humans have. The important condition for neuroplasticity is repetition, and repetition also happens to be a vital part of religious ritual. Emotional arousal plays a vital role in the formation of religious belief.
