I see the problem as...some still see it as a special gift to be able to know what the Bible says.
Some still believe that not all Chrisians have God's Spirit to understand what His Word means.
1 John clearly teaches we(Christains) are all Spirit filled(born from God) in 5:1...therefore...1 John 2:27 applies to all Christains...read and take comfort in your God given abilities.
Of course there are some "hard to understand"(2 Pet. 3:16) texts...Peter knew that there will always be that...but what Christains NEED to know is there clearly for those with God's Spirit to decern.
