The Voice of God

[ThePinsir]

To our resident Christians:

A lot of you say god talks to you. I used to hear it in church ALL the time, ALL THE DAMN TIME, and I still see it on facebook a lot. "God told me this or god told me to do that!" "God gave me this message!" "God told me to play this piece of music!" "God told me to give more money to the church!" "God told me that something amazing will happen in your life today!" Well, I have a few questions for you Christians concerning this communication:

1) When god speaks to you, is it an audible voice? Could you capture it with a sound recorder?
2) If not, is it a voice in your head?
3) If it is indeed a voice in your head, are there any means by which you can be CERTAIN it's not YOU talking, and simply wishing really hard it's god? Can you verify that this voice in your head can not possible come from something else?
4) Is the communication in English?
5) Does god have an accent?
6) Or is the communication from god just some sort of warm, fuzzy feeling you get?

Now, consider that god does not talk to atheists. Would you consider that this is because of a strong conformation bias? Would you say that this may be because in order to "hear from god" you must delude yourself into thinking he exists, then you suddenly start making up a voice in your head and saying it's god?

Bonus points:

7) What about Satan? Have you ever heard the devil or any demons talk to you?
