"...in 1 Nephi 15. Nephi is explaining Lehi’s vision of the tree of life to Laman and Lemuel when they ask the meaning of the river of water. Nephi answers in verse 27: “And I said unto them that the water which my father saw was filthiness; and so much was his mind swallowed up in other things that he beheld not the filthiness of the water” (emphasis added). Lehi’s mind was focused on the tree of life and getting his family to it to partake of its fruit! He didn’t even see the filthiness because of this focus.
"That was the answer! Keeping inappropriate media out of our home was a start, but a more direct and conscious effort to teach our children the gospel is what would ultimately be their best defense against anything that could lead them away.
"Because of this experience with the scriptures, my husband and I decided to redouble our efforts in teaching our children and thus keep our eyes on the love of God instead of the filthiness in the world."
