And yet even Jesus wept when he heard that Lazarus died, even know that he would bring him back to life. So while you may have no fear death, there still is grief. The surviving ones will grieve, how we deal with depends on whether, or not we have been taught to be resilient. It is the fact that we have to choose to continue living even in the face of great loss. We often don't realize that when we lose a loved one that we also lose the dreams we had for ourselves that included our loved one. I have watched my neighbor who was widowed at the age 32, still not realize that some of those dreams that she had of and for her family died along with her husband.
