That one line is "What makes us free / That must be stronger than we are".
It's a prayer. A quick and dirty translation of
the whole thing:
When music confuses the heart
And desire goes dancing
When the soul loses its way
Then only a prayer will help
God, protect us from the horror
The temptation that tempts us
Let us not stare into the deep
The abyss touches us
God protect us from the urge
To do forbidden things
Let the desire for destruction
Rest in the deepest depths of the soul
And forgive us our desire
For the dark and the night
Let us not lose your way
When the animal wakes inside of us
God save us from the yearning
To want more than we should have
And block our flight
When desire overcomes us
Sarah (simultaneously):
What sets me free / That must be stronger than I am
God save us from the yearning
To want more than we should have
And block our flight
When desire overcomes us
Sarah (simultaneously):
It carries me far / Because it is stronger than I am
God protect us from our wishes
Make us to temptation blind
Give us strength not to be weak
Make us stronger than we are ....
From Sarah & Krolock (simultaneously):
What sets us free / That must be stronger than we are ....
