It's called a really great book in the making!
Trust is involved in faith, IMHO. Belief is involved in faith. It's hard to untangle all of those concepts, many other words work that way also. Or should I say "too? As well?" Faith isn't necessarily based on a phenomena not seen or understood. It can also be based upon a history of facts as well. I have faith that there will be a tomorrow, because there have been many of them for thousands of years. I can't be guaranteed a tomorrow, but I'm not too darned worried about it. And that involves trust and belief.
Having faith in another person's word usually involves knowing the person well enough to be able to believe what they're saying, or if a first-time meeting, for the most part, some of us give the benefit of the doubt (faith) until or unless proven otherwise, that depending on the risks required or asked.
Faith isn't necessarily sheer hope without basis. (Indiana Jones when he stepped out onto the "air" while he couldn't see the platform, had been shown repeatedly that his writings and learnings had proven stable, so he had reason to trust that what he couldn't see, would turn out to be as stable.) But faith may make us take a bigger risk than we normally would in life. How many gamblers have faith that the NEXT one will be the big winner? How many huge successful entrepreneurs would have made it without faith?
