For a moment, let’s not think of GOD as a religious GOD but an entity that is superior to us. It can even be a particle. Crowds of people throughout history have described experiences of divine revelation they have had, religious or mystical experiences, visions, prophecy, and the like.
Some of those experiences occurred in daydreaming, during routine activities, and some were achieved as a result of activities like meditation, or in exceptional situations like near-death experiences.
There are many differences between the same experiences, but also many similarities are common, as William James demonstrated in his book “The Religious Experience to the Issue” and Rudolf Otto, in his book on holiness. I liked professor Gelman’s book “Experience of GOD and the Rationality of Theistic Belief,” which presented a philosophical argument stating that the accumulation of so much evidence constitutes proof of the existence of a GOD, just like any other phenomenon that we accept for its existence based on evidence.
