Over my 60 years of life I have heard many people say, "I believe..." in Jesus, in God, etc. Some say this with such a conviction or with such emotion or force in their voice.
One hard FACT for many of us to accept is, "Just because I believe something doesn't make it true." Belief is not the same thing as truth. Belief is not the same thing as reality. Spoken words of belief is a mental construct. Just because I say, or I yell, that I believe, that doesn't mean that I truly believe.
In reality, when it comes to belief, words have very little meaning UNLESS they are accompanied by a living out of one's beliefs. For example, someone can say, "I believe in God." but, by themselves, those words don't really mean anything. Truly believing in God encompases a whole lifestyle.
Honesty in all of one's interactions with people
