Quick answer

Knowing the right thing to do and failing to do it is sin. Sin includes not only wrongdoing but neglected good.

Overview

James closes this section with a principle defining sins of omission: the one who knows the good and does not do it sins. This broadens accountability beyond avoiding evil to actively doing what is right, fitting James's emphasis on faith working through obedience. It convicts every reader of falling short and points to the need for the grace and righteousness found in Christ alone.
