Based on the wording of Moroni 10:3-5, Moroni's invitation is about gaining a spiritual witness, not an intellectual one. That is an important distinction, and it is worth considering carefully.
Verse 3 focuses intensely on looking back in time and recognizing how merciful God has been to his children throughout time - then pondering that mercy. It doesn't ask the reader to ponder what the Book of Mormon has said up to that point; rather, it asks the reader to ponder God's long-suffering mercy.
Focusing on God's mercy
puts the reader's prayer directly into the realm of asking if the Book of Mormon
is "true" in a spiritual sense - more like "true north" than "factually inerrant".
Given how often the book includes comments about overlooking the
mistakes in it and the weakness of its writers, I think that's not
accidental. Thus, the prayer request becomes less, "Tell me if this book is historically accurate," and more, "Be merciful to me, as you have been to others throughout time, and answer my prayer." It's more of a connection to the divine than receipt of a factual answer - and I believe too many members and missionaries approach it as more of an intellectual question that asks if the details in the book are "accurate / right".
I think that simple difference is more than just significant.
