The argument is also used to demonstrate the difficulty of accepting the existence of any one God without personal revelation. Most arguments for the existence of God are not specific to any one religion and could be applied to any religion with equal validity. Acceptance of any one religion thus requires a rejection of the others, and when faced with these competing claims in the absence of a personal revelation, it is difficult to decide amongst them. Were a personal revelation to be granted to a nonbeliever, the same problem of confusion would develop in each new person the believer shares the revelation with.
