Jack Thomas’s family: I'm so sorry for your loss. I went through a similar situation and I was very helped by the hope that I found in the Bible in John 5:28, which says, "Do not amazed at this, for the hour is coming in which all those in the memorial tombs will hear his voice and come out". I am sending you a link with more information on this hope.

My deepest sympathy to the entire family for your loss. As the days continue to pass, may our loving Father give the entire family sustenance and strength you need to continue cope with the loss of your loved one. May you find comfort in your precious memories and love shared. May the words of 1 Peter 5:7 “ while you throw all your anxiety on him, because he cares for you” bring the entire family comfort and strength. Please accept my sincere condolences.
