A combination of Ordinary Time readings from Genesis and thinking about the Eucharist:

We work the soil, to reap its thorns and thistles;
we toil until we join the buried seed.
We sweat the days from birth to our dismissal,
and what we long for, we can never eat.

There is no bread that satisfies our hunger;
there is no wine can slake our endless thirst
until we taste the dirt we're buried under,
until the dust we came from comes to dust.

For we have poured out blood upon these furrows,
and thereof we have eaten bitter grains.
The firstfruits that we offered God were sorrows;
resentful and downhearted, we were Cain.

And this is the compassion of our maker,
the light that guides us into ways of peace:
He shapes himself of sod to be our savior;
the master serves his servants at his feast.

Not just the wheat Cain burned upon the altar,
but Abel's lamb disguised as simple bread.
So God accepts Cain's once-imperfect offering,
and Cain at last, at last can lift his head.

The dust we taste is not our bread forever,
and sorrow is not all we're doomed to eat.
Our seeds will finally grow to something better;
our bitter plantings blossom into sweet.
