nope, to think a thing is just that, has no bearing on faith, again, actors can think a thing a be representatives of feelings and opinions. (actors, also are known as professional liars)
though faith has bearing on what one may think at the time, faith is:
(OED)
I. Belief, trust, confidence.
1. a. Confidence, reliance, trust (in the ability, goodness, etc., of a person; in the efficacy or worth of a thing; or in the truth of a statement or doctrine). Const. in, †of. In early use, only with reference to religious objects; this is still the prevalent application, and often colours the wider use.
a mental state can be the result of one's faith, but faith isn't a mental state. it is true that faith comes by hearing, but people respond to what they are already ready to believe and trust. hence good ground rocky ground and the like in the Lord's parable.
