Salvation unto Us Has Come, LSB 555.

4. From sin our flesh could not abstain,
Sin held its sway unceasing;
The task was useless and in vain,
Our guilt was e'er increasing.
None can remove sin's poisoned dar
Or purify our guileful heart—
So deep is our corruption.

9. Faith clings to Jesus' cross alone
And rests in Him unceasing;
And by its fruits true faith is known,
With love and hope increasing.
For faith alone can justify;
Works serve our neighbor and supply
The proof that faith is living.
