I am so sorry to hear about the tragic loss in your family, someone so young. Sometimes when there is a death people say 'it was God's plan' or 'God's will' as if God is responsible for things like this but James 1:13 explains that God has nothing to do with such a painful event. Instead, he promises to bring to life again those in his memory who have died. John 5:28,29; Acts 24:15; Revelation 21:3,4. Please accept my deepest condolences.
