Even wondered about those parts of the Bible that talk about so and so being 'righteous and blameless'?
Sola Panel has a really clear post on the topic.
Especially interesting is how Psalm 14 (quoted in Romans 3:10-12) is not actually a proof text that noone at all is righteous:
Psalm 14 by itself doesn't prove this point, but according to Paul, when you see Psalm 14 as part of the Bible's overall story, the picture adds up that there is no-one who conforms to the ultimate standard
