What good does it do you if you don't know how to read it? Clearly there is a problem here. The Bible does have some clear passages that anyone can understand without needing someone to explain. Let me start with:
Acts 8:30 And Philip ran thither to him, and heard him read the prophet Esaias, and said, Understandest thou what thou readest?
31 And he said, How can I, except some man should guide me? And he desired Philip that he would come up and sit with him.
32 The place of the scripture which he read was this, He was led as a sheep to the slaughter; and like a lamb dumb before his shearer, so opened he not his mouth:
33 In his humiliation his judgment was taken away: and who shall declare his generation? for his life is taken from the earth.
34 And the eunuch answered Philip, and said, I pray thee, of whom speaketh the prophet this? of himself, or of some other man?
35 Then Philip opened his mouth, and began at the same scripture, and preached unto him Jesus.
We also see Jesus explaining the Scriptures. People needed help, it seems.
Luke 24:27 And beginning at Moses and all the prophets, he expounded unto them in all the scriptures the things concerning himself.
I assure you too that the good people at Berea had read the Scriptures and they also knew there were things they didn't understand. I am always amused when people say the Bereans used the sola scriptura method of deriving truth. They had had the Scriptures but didn't derive truth until something else got said. Yes, I said said. Paul and Silas gave them a "word." Then the Bereans wondered if that could be right and searched the Scriptures to see if it could be so.
Acts 17:11 These were more noble than those in Thessalonica, in that they received the word with all readiness of mind, and searched the scriptures daily, whether those things were so.
There were Jews too who thought they had the Law of Moses because they had the five written books. They did not. They had written words, and could not discern its true meaning.
Jeremiah 8:8 8 How do ye say, We are wise, and the law of the Lord is with us? Lo, certainly in vain made he it; the pen of the scribes is in vain.
9 The wise men are ashamed, they are dismayed and taken: lo, they have rejected the word of the Lord; and what wisdom is in them?
They had written books but they did not have the Word of the Lord -- the Living Word -- they had ink on paper.
Ha, ha, there were Jews who had searched the Scriptures over and over and still didn't recognize Jesus when he showed up.
John 5:39 Search the scriptures; for in them ye think ye have eternal life: and they are they which testify of me.
You could read all you want about how to repair cars, but if you couldn't recognize the car parts named in the manual when you see them, it does you no good. You could memorize your entire car manual; but if the battery needed to be replaced and you couldn't recognize a battery when you saw one, what good did the book knowledge do? All you have are words and ideas. You can't relate them to reality. Doing that can make your head spin because you're not in reality -- you can put yourself in some imaginary world.
