The next two lines in that verse are "That with all our fallen race / In our depth of degradation," sung to these musical phrases from "Ach, was soll ich Sünder machen":
Both phrases descend, musically giving a sense of "fallen" and "depth of degradation."
An-other feature I noticed is the slant rhyme in the lines "Giving us the gift of faith / That we fear not hell nor death" at the end of the third verse. That "faith" and "death" don't perfectly rhyme illustrates that for those with faith, there is no death. "Death is swallowed up in victory" (1 Corinthians 15:54).
