When you hear it
Does it thunder?
Or bring that chill up your neck?
Does it whine in a key
you know is real?
Is the world split open
by its crack?

And did it begin
as a small worm in your heart
A throb that pulses your brain
and grows and throws
its shadow, too,
on the shapers of your world?
Well its power is
the breath of God
and the longing for his presence
grows when that song
is in the air.

A side note of some interest: A preacher friend of mine who does not mind my deep agnosticism began one of his sermons with this piece. I was rather proud of that, even though the subject of the poem is the effect of a poem on the auditor, not a declaration of a relationship to God, which I use here in metaphoric sense.
