Faith to Desire to See

After Nephi was told of Lehi's vision of the Tree of Life, he expressed a desire to see the vision himself. I don't think that this implies that he doubted his father at all. This wasn't Nephi asking to see evidence that Lehi had truly seen a vision. Rather, I think it was more that he wanted to dig into the vision himself. We do something similar when we check out a book or movie someone tells us about, not because we doubt their report that it was a good book or movie, but because we believe them. I think that Nephi wanted to see the vision for himself because he believed that it was a vision that was worth seeing. Wanting to see the vision for himself wasn't an admission of doubt. It was an expression of faith.
