the passage (uk) - a good & useful life begun lyrics

he filled a screen with his mouth
a room with his voice
our minds with fear

he spoke of love
he spoke of comfort and god
and his authority (within these walls)
to knock us back to shape (how do we mark it out)
for the good of our souls
and how we all
each one of us
should set an example
to children (within these walls)
by leading (how do we mark it out)
a good and useful life (this good and useful life?)
