That's called faith by who? Can you find me a quote, not a personal anecdote, so we can be on the same page?
As far as the Bible goes, almost every story where God sends someone to speak to others, there is some supernatural sign given as evidence. Moses turns a rod into a serpent, Elijah rains fire from heaven, Jesus does countless miracles. You have to know God is real before you have faith in him.
