There is no possible explanation for the pain that is felt when you lose someone in death. The true numbness that is felt when someone close to you dies is not something that is not easily defined. It is comforting to know that we are not alone. I recently lost my brother and my uncle within the past 3 months, so I know the feeling that your family is experiencing. I have always found comfort in the Bible, specifically at 1 John 5:14. There it states: "And this is the confidence that we have toward him, that, no matter what it is that we ask according to his will, he hears us."
