I'm so sorry for your loss. May the God of comfort comfort you during this difficult time. 2 Corinthians 1:3,4. At John 5:28,29 God promises to resurrect our dead loved ones. I hope that gives you hope.
My deepest sympathy on Margaret's passing. She meant the world to me. I was blessed to have her in my life. She is in a better place now.... no more pain! God bless!
