What is the belief in the correctness of the Bible based upon?

Many Christians believe that the writing of the Bible was inspired by God, and that its content is (essentially) correct. I would like to understand on what this belief is based. Obviously it cannot be based on the Bible itself, this would be circular reasoning. What I could imagine: - through prayer or your personal connection with God you came to this conclusion. - there is someone (living, or from the past) that told you this and fully trust that person. - Maybe something else?
