Just over two years ago our family went through a similar experience. Rick's friend and business partner was killed in a helicopter accident. Rick came to stay with us for several days; days filled with shock, grief, and heartbreak, it was probably the most difficult thing he had ever dealt with.
We spent a lot of time praying with him, relying on the mercy and love of the Savior to give comfort and understanding.
I love this statement by Elder John H Groberg ~
There is a connection between heaven and earth -I am so grateful to know that life goes on after death, that this life is just one part of our loving Father's plan for our happiness. Although death always brings unbelievable sorrow and heartbreak, it is tempered by the peace and love of Jesus Christ who stands waiting for us to turn to him in our times of need. He is the one sure source of comfort, understanding, and peace. Rarely does our problem disappear when we turn to him, but always he offers to bear it with us.
Finding it makes everything meaningful, including death.
Missing it makes everything meaningless, including life.
