All gods are subjective
I pointed out to him that EVERY religion has followers who claim the same thing. I've talked with Muslims and Hindus who assured me that their gods were real because they experienced their gods while praying, or while worshiping. I know that all other religious traditions I've read about have those who claim mystical experiences, personal encounters with the divine.
It seems obvious to me that all these reports indicate a subjective experience. Obviously, YHWH, The Great Spirit, Allah and Shiva can't all be giving the SAME feelings and head trips to their respective adherents.
My email concluded with a classic thought. He urged me to use my heart more and my mind less. I said that people using their minds less is a cause of too many of the world's problems.
