What is truth?

Truth is the word from the mouth of a child,
One clear drop of rain when the weather is mild,
A message without limits, judgments, or bias.
The shapes on the earth when the sun is its highest.

It's the bright flash of lightning as it strikes in the sky.
And last words at a bedside when one comes to die.
The pain of a mother when her son goes to fight,
And the whisper the wind howls out late at night.

A hungry man digging in the dumpster out back,
And the desperate scraps that he keeps in a sack.
The wounds of a man who crossed the wrong gang,
His life ended short by the sound of a bang.

Words come to life when the world is the worst,
When hearts are in need and ready to burst.
Our lies are laid bare by the things that we fear,
But when all hope is lost then truth will appear.
