Jesus said the Holy Spirit would lead us to ALL truth. That means there is no truth that we are lead to that doesn't have His involvement. It also means anywhere we think we've gotten truth where we can't recognize the involvement of the Spirit is worth calling into question. Preachers, teachers, authors, and even scripture we've learned from are worth our time taking to God to be taught by Him.
There is an untold amount of false & ignorant teachings & interpretations out there. Just because you are reading the bible doesn't mean it isn't being distorted through the lens you unwittingly look through. Turn to the Spirit of God before turning to the scriptures because it is unwise to wholly trust your interpretation of scripture. The Spirit may point you to the scriptures to teach you the truth and He may not. God is living and living inside of you. Trust Him more than what you've heard and speak with Him.
