"If Jesus healed the Nephites, why hasn't He healed me?"

Today I was teaching 3 Nephi 17 (I'm a seminary teacher) and we talked about how Jesus has the power to heal all of us, no matter how we are afflicted. It was a powerful lesson because of what the students shared. I also have had my own experience of Jesus healing me...though it took many many years as well as many professionals for me to get to a point to where I was healed.

After class today, I had a student ask if she could stay in the classroom because she could not face leaving and seeing everyone the way she was. I looked and saw her face, and she was weeping. She told me how hard it is for her to hear lessons like this.

(A little context on her, she is 15 and has so many health conditions, no doctor knows exactly what she has. At the beginning of the school year last year, they had all of her teachers sit down with the school medical professional as they explained all of the isolated conditions she has. The least severe of the conditions she has is diabetes. She is also hooked to a feeding tube so she has to carry around a small backpack everywhere she goes, including during school. I don't remember the rest of the conditions she has, but it impacts every aspect of her life. The medical professional mentioned that no doctor has ever seen a case like hers. The young woman has mentioned that it takes over her entire life, and she never gets to be a normal teenager like all her friends.)

She hurt hearing this lesson about how Jesus would heal these people when she's been waiting for 15 years and has never seen her healing or her miracle. Her question was, why would He give that to the Nephites or the woman with the issue of blood, for example, but not to her?

I had so many talks and scriptures that I knew I could share with her but instead, the Spirit told me to just sit and listen and mourn with her instead. So I did. I didn't say much, but I just sat and listened to her, mourned with her, and tried to comfort her as best I could. I feel like that was the best course of action, because I felt in that moment, words would not have helped.

However, I am curious. I know this is an age old question but...if you were to respond with words, from your experiences that you have had or what you know, how would you respond to a young woman with this question?
