I just wanted to leave my condolences and a comforting scripture. John 5:28 reads- 'Do not marvel at this, because the hour is coming in which all those in the memorial tombs will hear his voice and come out." This speaks of a resurrection of our dead loved ones. I know you don't know me but you and the family will be in my prayers.
It was not God's purpose for humans to suffer or die. When you get a chance visit http://www.jw.org/en/bible-teachings/questions/our-suffering/. This site brought me so much comfort when I was going through a hard time.
