A Mormon amateur apologist writes:
I have come to know the Book of Mormon was translated by the gift and power of God by reading it, applying it’s teachings, and asking God if it is true. Through applying it’s teachings, I experienced the most profound change from wickedness to righteousness. When I asked God, He bore witness to me more powerful than mere dna tests that it is true.
It’s a familiar sentiment. But it’s not one restricted to the Mormons - people who would loudly (and rightly!) deny that the Book of Mormon has any status as Scripture would say much the same about their own beliefs.
But why should they be taken any more seriously than this Mormon ?
