Must not be subjective.
It is required of all readers of the Bible to be objective.
No subjective person can study the Bible well, for he is not apt to learn.
Many people do not hear and understand because they are too subjective, not because their brains are inferior.
Since they live wholly in their own thoughts, they are unable to hear other people’s words.
Being already filled with their own opinion and ideas, how can they take in another’s words?
