How to select which supernatural to believe?

[Jehanne]

Yes, of course there has to be independent reasons for believing God exists.I said that prophets are the only way to know God's intentions/true religion/message. No religious experience of any kind can by itself establish God's existence.

One establishes God' existence first, then argues that He's benevolent, and finally shows that a particular religious experience of a prophet is most likely caused by God, as a result of his benevolence/his willingness to reveal his intentions. I don't know nor ever saw any other promising way to argue for theism from first principles.

If the prophets truly are from God, why can't they provide clear & convincing evidence of such??
