This is a great post. I think you're right, religious people sometimes do feel guilty for grief because it's like you don't have enough faith to see things through, to trust that God knows what He's doing. In contrast to that I've always particularly liked the part where Jesus went to his friends' house and found that Lazarus had already died. And instead of being all happy! because Lazarus had gone to a better place, he sat down and cried. Grief and faith are not mutually exclusive.
