The end of "Messiah (Christmas Portions)" by Mark Doty:
Aren't we enlarged
by the scale of what we're able
to desire? Everything,
the choir insists,might flame;
inside these wrappings
burns another, brighter life,
quickened, now,by song: hear how
it cascades, in overlapping,
lapidary waves of praise? Still time.
Still time to change.
