Sin keeps us from wanting to read the Bible. If we sin knowingly we often feel we do not have the right to read it.
Satan knows that Gods word is the greatest weapon that we have to fight him with. He wants to make us stay out of the word. By making us feel guilty he gets us to keep away from the Bible. What we need to understand is that God wants us to read His word every chance we have. He is not the one condemning us.
