Offering sincere condolences. I am so very sorry for your loss. Please know that sickness, tragedies and accidents are not cause by our Heavenly Father (Ecclesiastes 9:11; James 1:13) Although these terrible events do happen God has promised to undo them in his time, that time is very near to come and there will be a bringing back to life instead of losing. (John 5:28, 29) No doubt this is a very difficult time for the family. Please continue to rely on our Heavenly Father and the hope and comfort He provides through His Word the Bible. (2 Cor. 1:3,4)
