For a boy who would someday become prophet, young Nephi had remarkably simple faith.
Going into the beginning of the Book of Mormon, all he really knows it that God exists and that he loves us (1 Nephi 11:17). Nephi didn't know really anything about Jesus Christ, His future sacrifice, the plan of salvation, the doctrine of baptism... and yet, Nephi's simple faith was enough to carry him through some of the toughest trials of his life.
As Nephi exercised his simple faith and expressed his desire to gain more knowledge, God revealed more to him about the future, the gospel, and even helped Nephi understand Lehi's vision. That's a great example to me: gospel knowledge does not equal gospel faith. And sometimes, especially when we're struggling, knowing that God "loveth his children" can be enough for us.
