I've had 3 friends lose a child unexpectedly and have seen them suffer thru the grieving process. One of my friends lost her 20 yr old son in an accident. He lived for a week and they had to make the decision to remove him from life support. He wasn't saved and my friend became very bitter and angry. Everytime I spoke with her, she'd say, "I'll never forgive God." It was heartbreaking. She wasn't at all that way before her son died. Then a couple of years after his accident, she was in a car accident and died. I've always believed the Lord just took her on home because she became so hard-hearted and refused to glorify Him in any way.
