“All our righteous deeds are like a filthy garment; And all of us wither like a leaf, And our iniquities, like the wind, take us away.” – Isa. 64:6
All our good works, ALL of them, are contaminated. They do not and can not save us.
Only Jesus saves.
Of course, that doesn’t mean we don’t do good works: Good works don’t save people, but saved people do good works.
Martin Luther said God doesn’t need our good works, but our neighbor does.
