What is the religious defense of this Jesus Christ quote?

[Disagreeable]

I’ve been told to go read the Bible probably 50 times by now.
I am including other forms of that sentence such as “have you read the Bible?”
or
“Have you read the entire Bible?”

and “read it some more”
and “read and pray on it”
and “you might have read it but you certainly did not understand it”

It is implied that reading the text will convert the non-believer.
There isn’t much to understand. The text is mostly straightforward.

One christian told me that being a priest is like being a heart surgeon: only the professionally fully understand it.

This rationale always makes me laugh, as if the world's foremost expert on the Harry Potter novels, best understand whether wizards are real. The bible is a book, books are man made, the bible is not just fallible, it is demonstrably erroneous in places. 

The Genesis creation myth, and the Noah flood myth, are two examples that not only contain risibly erroneous claims, but whose core message is contradicted by objective scientific facts.

I never got past Genesis. It was so BORING.
