My condolences for your loss.  Note where comfort originates for all at Romans 15:5 Now may the God who supplies endurance and comfort grant you to have among yourselves the same mental attitude that Christ Jesus had,"  He also gives this promise at Revelation 21:4 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.”
