In the Bible, God spoke directly to Abraham. He spoke directly to Moses. He spoke directly to Job. But to your neighbor down the street?
Most people reading the ancient scriptures understand these accounts of hearing God’s voice as miracles that really did happen but no longer take place today, or maybe as folkloric flourishes to ancient stories. Even Christians who believe that miracles can be an everyday affair can hesitate when someone tells them they heard God speak audibly. There’s an old joke: When you talk to God, we call it prayer, but when God talks to you, we call it schizophrenia.
Except that usually it’s not.
Hearing a voice when alone, or seeing something no one else can see, is pretty common. At least one in 10 people will say they’ve had such an experience if you ask them bluntly. About four in 10 say they have unusual perceptual experiences between sleep and awareness if you interview them about their sleeping habits.
I supppose it depends upon what those voices are saying.
