Only two families inhabit earth

(
Henry Law, "Deuteronomy" 1858)

Only two families inhabit earth.
 
In principle,
in taste,
in habit,
in desire—
they are as separate as . . .
  light from darkness,
  cold from heat,
  life from death.

There is the serpent's seed.
There is the heaven-born race.

There is the world.
There is the little flock of grace.

There is the broad road.
There is the narrow way.

There are the sheep.
There are the goats.

Hence the importance of the question—
"Have you escaped from nature's thraldom?
 Do your feet tread the upward path of holiness?
 Do you belong to Satan—or to Christ?"
