What if?

So I have been thinking a lot about our mortality lately. The main reason is because I have been following this little boy's story on his family's blog. He has courageously battled Leukemia for the past couple of years and last month was going through his last treatment when the doctors found out that his cancer had returned and that it was resistant to treatment. He is only 7. He only has several days to months to live. So my question is what if your child was dying? What would you do with your last moments with them? How would you live your life? I can't imagine the pain this family must be going through. You try to live your life as if there is no tomorrow but it is hard to when life happens. I am happy that this family has the gospel and knows what is on the other side. How tragic would it be to not believe that there is life after this. I feel comforted in what Joseph Smith said about those who die young
“We have again the warning voice sounded in our midst, which shows the uncertainty of human life; and in my leisure moments I have meditated upon the subject, and asked the question, why it is that infants, innocent children, are taken away from us, especially those that seem to be the most intelligent and interesting. The strongest reasons that present themselves to my mind are these: This world is a very wicked world; and it … grows more wicked and corrupt. … The Lord takes many away, even in infancy, that they may escape the envy of man, and the sorrows and evils of this present world; they were too pure, too lovely, to live on earth; therefore, if rightly considered, instead of mourning we have reason to rejoice as they are delivered from evil, and we shall soon have them again"
