Personal revelation


 * "I believe in God because he personally revealed himself to me."
 * "I saw a ghost with a friend of mine - I am not a liar, an attention seeker. Neither was I overtired when this happened."

Counter-Arguments
The problem with personal revelation is that it cannot be verified independently. The person who received the revelation may exhibit a long-term change in character, or other convincing signs that he or she had some sort of emotional experience, but it is impossible to tell what actually happened.

Furthermore, the revelation never includes information that the recipient could not possibly have known and can be independently verified, such as the time and location at which the next earthquake would occur, or any number of as-yet-unsolved problems in science, or even the meaning of "frontlets" in the Bible.

Another problem with personal revelation is that so many people from other religions experience it too, yet they don't all experience the Christian god. If personal revelation in the case of Christianity is to be believed then one must also believe the Muslim when they say they've had personal revelation of Allah. More than likely it is an experience that they then attach to information they received while growing up. If you were born in the US, you more than likely grew up at least knowing some Christian concepts. If you were born in the middle east, you more than likely grew up learning Islamic concepts.
