Back in 1986, when the missionaries approached me and asked me if I wanted to study the scriptures with them, they started us reading in 3 Nephi 11. So, these chapters in the Book of Mormon are very special for me, because I read them as I started to build my testimony that the Book of Mormon is the word of God.
I did not do anything special other than that to build my testimony. I prayed about the Book of Mormon’s testimony, and I have received a witness from the Holy Ghost that it is true. I guess that you could also say that praying was also something special that I did. Although, I am not better than anyone else as a result of witnessing what I have witnessed.
What I am getting at is that in 3 Nephi 12:13-16, Jesus repeats what He said those in Jerusalem, that we who have received His words are salt and a light to the world. I believe that anyone else can also witness the truthfulness of the Book of Mormon by doing what I have done.
