Glad to. He asked you to pray about some scriptures and you mock that.... Wisdom to understand the scriptures is something well worth praying for.
Truly you don't understand that verse! James does not say pray about the scriptures. In order to believe that you must not even know the definitions of the words you are using:
Wisdom: The quality of being wise; knowledge, and the capacity to make due use of it
Understand: To have just and adequate ideas of; to apprehended the meaning or intention of; to have knowledge of; to comprehend; to know
Knowledge: The act or state of knowing; clear perception of fact, truth, or duty; certain apprehension; familiar cognizance; cognition.
Now, that you might "understand" that James is not teaching that we should pray about the truth of any man's words, you might figure out that James is saying something entirely different. Here, I'll help you out: James is teaching us that if any man does not have the capacity to make due use of what he already knows to be true then he should ask God.
Now, can you find me a single verse which teaches that I should pray about the words of another man to see if they are true or not? While you are vainly searching for that, can you find me a verse which teaches that I should pray about whether or not the Bible is true?
