Robert’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.
As the days continue to pass, I hope you find comfort and support in the people that surround you and the wonderful memories you carry in your mind and in your heart. May the words of Matthew 5:4 “ Blessed are those who mourn, for they will be comforted” bring the entire family comfort and strength. Please accept my sincere condolences.
