The book of Mosiah starts with a testimony of three important things, and a wonderful observation about the nature of faith.
In Mosiah 1:3-5, King Benjamin refers to his family’s copy of the Hebrew scriptures, and he teaches his children about how crucial the scriptures are in preserving spiritual culture. In the next verse, he says:
O my sons, I would that ye should remember that these sayings are true,
and also that these records are true.
And behold, also the plates of Nephi, which contain the records and the sayings of our fathers from the time they left Jerusalem until now, and they are true;
and we can know of their surety because we have them before our eyes. (Mosiah 1:6)
Here, Benjamin testifies of the truth of three things: his own teachings to his children, the ancient scriptures, and the collected teachings of recent prophets.
This would be like any of us telling our children, “I know that what I teach you in our home is true, and that the scriptures are true, and that the words of our prophets in the church today are true.”
Which is exactly what we do say! Another way the Book of Mormon is relevant for us.
But the final clause is my favorite. According to Benjamin, what can his children look to as proof of the reality of the truth of these things? The fact that the documents actually exist!
How often we overlook the best evidence for the truth of the Book of Mormon and the reliability of our leaders today: the obvious nature of their content, and the very fact that they are real, that we have them physically available for examination. Consider how unlikely that would be if these things were fraudulent, and you see what Benjamin meant.
