Psalm 130

Though great our sins and sore our woes
His grace much more aboundeth;
His helping love no limit knows,
Our utmost need it soundeth.
Our Shepherd good and true is He,
Who will at last His Israel free
From all their sins and sorrows.

-Martin Luther

Purchasing Grace

...Still I feel the old clinging dirt of wanting to deal so with God that I may contribute something, so that he will have to give me his grace in exchange for my holiness.

-Martin Luther
