My 7-year-old has set a goal to read the Book of Mormon this year before his 8th birthday.
I set up a simple reading schedule for him and started in on Monday night. On Tuesday night, as we were reading 1 Nephi 2:16-17, we got talking about how he can know if the Book of Mormon is true. I explained Moroni's promise and we discussed what it feels like when the Holy Ghost tells us that something is true. I told him that when the Spirit speaks to us, we feel warm and happy inside and we might even have "happy tears."
He got very concerned and asked, "But Mom, what if it's not true?"
I answered, "Well, then you'll feel confused and dark and cold inside. But I can tell you for myself that I know it's true."
I kissed him goodnight and tucked him in.
The following morning, he came into my room where I was reading my own scriptures. He snuggled up to me in bed with his Book of Mormon in hand and said, "Mom! Guess what?"
"Guess what! I did just like you said last night, and guess what?"
"Well, I prayed just like you said and I felt that warm touch inside!"
...and a little child shall lead them.
