Where is God?

From C.S. Lewis' A Grief Observed:

"No one ever told me that grief felt so much like fear. I am not afraid, but the sensation is like being afraid. The same fluttering in the stomach, the same restlessness, the yawning. I keep on swallowing.
...

"Meanwhile, where is God? This is one of the most disquieting symptoms. When you are happy, so happy that you have no sense of needing Him, so happy that you are tempted to feel His claims upon you as an interruption, if you remember yourself and turn to Him with gratitude and praise, you will be -- or so it feels -- welcomed with open arms. But go to Him when your need is desperate, when all other help is vain, and what do you find? A door slammed in your face, and a sound of bolting and double bolting on the inside. After that, silence. You may as well turn away. The longer you wait, the more emphatic the silence will become. There are no lights in the windows. It might be an empty house. Was it ever inhabited? It seemed so once. And that seeming was as strong as this. What can this mean? Why is he so present a commander in our time of prosperity and so very absent a help in time of trouble?

I am reminded that the same thing seems to have happened to Christ: 'Why hast thou forsaken me?' I know. Does that make it easier to understand?"
