Not sure where you are headed with this, but I would say that "belief" can mean "mental assent," meaning, "I accept this as the truth."
But it could also be "trust in something or somebody," right? "I truly believe in my team! I just know they will win."
So to believe in God seems to include both notions. You can believe God exists "mental assent to the proposition," and you can say, "I truly believe in God! I know he is doing a good thing in the universe."
There are documents that support theism, but there are also rational arguments, and so-called "natural revelation."
