We can use it to shine on the dark corners of life - or we can cut the light out entirely. It's our choice. As the creations of the same Creator, I believe that we have a moral obligation to shine as brightly as possible for one another. Imagine that you are entering a dark place. We are strange creatures.
Animals have no hesitation in getting to know one another.
We, on the other hand, sometimes need extraordinary circumstances. We may see the same people day after day for years on the bus, on the street, in the building where we live or work, and never even say hello. But if a disaster of some kind happened, these are the very people who would probably save us or vice versa. Bring down the defenses, make the first step. Say hello to someone.
