My sincere condolences to the family may you find comfort in Revelation 21:4

We are so sorry for your loss. When this happens in our family we need more than human strength. God and his Son can provide what we need. Please review these scriptures : John 5:28-29 “Do not be amazed at this, for the hour is coming in which all those in the memorial tombs will hear his voice 29 and come out, those who did good things to a resurrection of life, and those who practiced vile things to a resurrection of judgment.”
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.”
