My wife and I would like to offer our sincerest condolences on your loss.
I can’t imagine the pain you must be feeling but I hope you are coping ok. A scripture that has helped many persons to find comfort when a loved one dies is found at Rev 21:3,4. It says, ‘’With that I heard a loud voice from the throne say: Look! The tent of God is with mankind, and he will reside with them, and they will be his people. And God himself will be with them. And he will wipe out every tear from their eyes, and death will be no more, neither will mourning nor outcry nor pain be anymore. The former things have passed away.” We look forward to the time when there will be no more sickness and death. In the mean time Jehovah God can help us to cope.
