2000 years ago Jesus spoke about such teachers who think they are the only ones who can explain the Bible. Today people should be aware that it is the Scriptures itself that can explain everything and that it is Jeshua, Jesus Christ, whom we should follow as the most perfect teacher.
We can look at the biblical authors as Witnesses for Jehovah God, the divine Creator of many universes, as people who were called to testify before humankind and in several occasions were even willing to give up their life for what they considered to be the truth.
To come to a faith life of truth we will need a solid foundation. to explore the truth one is best to use a trustworthy book. It may look strange but there is a Book of books, containing 66 books by 40 authors which is literally of extraterrestrial origin.
