Faith is a measure of irrationality

[Mudhammam]

Faith may work for the self in the same way I might feel like a better and more inspired person if I begin every morning by jacking off or sacrificing a cat to an ancient Mesopotamian deity. If that's what gets your socks off, have at it (well, don't actually sacrifice any cats).

The moment you begin to tell others that your interpretations of said inspired experiences are correct for not only yourselves but that others ought to agree with your interpretations, you'd better provide some evidence or expect the most contemptuous of ridicule.
