Peace on earth, starting with a lot more good will towards one another.
I like to look up at the stars in winter. I don't know if the star that the Three Kings are said to have followed looked then more or less as it does now, but I do tend to think of starlight as a timelesss backdrop for the short scale of our human history so far.
So on a winter's night when I look up and see the stars still sending out their light from so far away, so long ago, usually I end up thinking that the ongoing expansion of their light to the farthest corners of the universe is its own wonderful message for anyone to take away from a night sky. Nothing to do with religion! Everything to do with hope.
