Innocent faith

Hello Rabbi, I heard two lessons that the Rabbi gave on pure faith and I wanted to ask about them. The Rabbi said that in his opinion, in order for a person to be considered a believer, his faith must be expressed on two levels: 1. Consciousness. on. His intuitions are on the side that had all the arguments before him. And in this sense, even a person who believes in his own testimony has no reason not to investigate the MNM. If he discovers that he still believes, nothing has happened (and even if there is a profit), and if he discovers that he does not believe, it is only a retroactive declaration that he has always been like that.
If I understood correctly, the Rabbi meant all theoretically possible arguments. And this is essentially a process of exposing what exists in it. According to your words, is the very ‘what exists in it’ at the potential level something that can change, or does each person have their own potential intuition? And if it is not changeable, and there is God, does it turn out that all people actually believe (as Rabbi Kook claims, as far as I understand)?
thanks
