The light shines in the darkness, and the darkness did not overcome it.
Shadows are not dark. They are light demonstrating the position of some thing. You do not get “real” shadows on cloudy days. Only in the sun do you witness clear shadows.
The same is often true of life. We do not see the real position of things until it’s shadow is made clear by a shaft of light striking it. Life is illuminated by the shadows. We only see them when a ray of sun breaks through.
When I become aware of dark shadows invading my life I do well to remember that this defining of my existence is only made possible by a ray of sun breaking through. Shadows help to define our lives in brilliant ways.
