I find it funny that people most often associate hope with light.
I think that hope is like sitting in the dark, with faith, and it only takes a single flame of doubt to cause shadows. It takes more courage, faith and hope to sit in the dark. Just as it only takes the smallest doubt to shatter the darkness, to cause shadows.
Think about it, is sleeping with the light on not doubting your own strength to sleep without it? To sleep in the dark?
Hope is sitting in the dark without turning the light on, ever.
