If you don't see the moon at night, it isn't because the sun is gone, it's because the Earth is in the way.
When people look at you, do they see the SON reflecting through you, or is the Earth in the way? Take a minute to reflect on this and then make a change to reflect Christ better to those around you.
For at one time you were darkness, but now you are light in the Lord. Walk as children of light.
