This passage from Galatians 1 (NIV) made quite an impression on me just now-
11 I want you to know, brothers and sisters, that the gospel I preached is not of human origin. 12 I did not receive it from any man, nor was I taught it; rather, I received it by revelation from Jesus Christ.
Paul had heard the Gospel from men and rejected it, helping out with the persecution of the early church; the stoning of Stephan in Acts had Paul approving of that action. It wasn't until his trip to Damascus that he met Jesus face to face and got the message.
The Bible is a secondary source. God is the primary source. People of the Church are God's messengers, but it is God who is the ultimate speaker. The Bible has a plethora of wise thoughts, but it is the Holy Spirit that brings them to life to the believer.
Jesus cut out the intermediaries and talked directly to Paul. While it's typically less direct, being taught by the Spirit can help achieve that disintermediation. Merely reading the Bible can lead to isogesis, reading your biases into the passage rather than letting the passage and the Holy Spirit transform those biases; studying the word properly can't be done alone.
