I would like to express my sympathy and condolences at this time. Also, at Rev. 21;3,4, it tells us that sickness and death will be done away with forever and Isaiah 25:8, it tells us that God will swallow up death forever and he will wipe away the tears from all faces. I hope you find comfort in these words during your loss.

With heartfelt sympathy. Please accept my deepest condolences. May you continue to cherish your precious memories, and may you find comfort in Jehovah the God of all comfort. For he promises to give you the strength to endure these difficult days. (Isaiah 41:10)

May you find comfort in knowing that your dear one is safe in the memory of God, who will remember every detail about them and bring them back again. (John 5:28,29) My sincere condolences to your family.
