There are many articles on the internet that counsel people not to pray to know whether the Book of Mormon is true. You should check them out and add your voice to the conversation of articles that allow them.
In this article, the author makes what I believe is a solid argument for why putative truth can't be evaluated by one's feelings about it. He uses scriptures to support the idea that one must use their minds and reason about putative truth.
Then he takes a huge turn into a less supported conclusion:
"In summary, then, we should never be tempted to accept the Mormon challenge to pray about the Book of Mormon. Rather, we should use our minds to investigate its origin, examine its teachings, and compare it with Scripture. In so doing, we remain consistent with Scripture and subject a book that claims to be the Word of God to a factual and realistic assessment."
I am writing this post because I think this is a great specific example of what I've referred to as "uneven application of reason." This is what the Lord told me when I asked how so many intelligent, accomplished people could be so right on so many things, but so obviously wrong on others. He said they apply their reasoning unevenly, and that if they exercised their full reason as honestly on all things, they would advance much closer to him than they are.
This author is obviously intelligent, and has obviously spent a lot of time studying the scriptures. However, he fails to apply his intelligence and scriptural familiarity to the most important part of his analysis: how does one test truth?
He says "we should use our minds to investigate its origin, examine its teachings, and compare it with Scripture."
Where does the Bible say that origin investigations are a test for truth?
The people from his hometown bitterly rejected him multiple times. The first time he tried preaching to them, they tried to throw him off a cliff. He came back after they had heard the stories of his teachings and miracles in other towns, and they had such strong unbelief that he couldn't do any mighty miracles there. It was this rejection that caused Jesus to lament that prophets are never accepted by those who knew them while they were growing up.
Where does the Bible say that comparison of new truth to what you currently believe is a test for truth?
Jesus explicitly preached that new truth would frequently require letting go of what was previously considered to be true. For example, see his teaching about the problems of patching old garments with new cloth, or putting new wine into old bottles.
He said he came to make all things new. He explicitly replaced prior beliefs held by the people:
What is the test for truth that Jesus gave?
He said: If any man will do his will, he shall know of the doctrine, whether it be of God, or whether I speak of myself. (John 7:17)
Do you think this author has read and attempted to live even one idea from the Book of Mormon? I promise you that he has not.
It is so sad to see someone equipped with all the tools to approach God, and yet use them to prevent his own progress towards him. How near someone can seem to God, and yet be so far away.
