My sincere condolences to the family. A beautiful scripture that will comfort you is found at Revelation 21:3,4. All of the sufferings we go through will be replaced with peace, serenity, and eternal happiness. (Psalms 37:10,11,29 and Isaiah 65:21-25) We can see our loved ones through the resurrection. Having a life that was meant to be in the very beginning . (John 5:28,29 & Acts 24:15)
