The article discusses how theologian Barth examines human action in relation to divine action. It raises questions about whether Barth can explain human action as the person's own, maintain its consistency when influenced by divine action, and ensure the person remains fully human with all their abilities. Barth addresses these questions, but struggles to explain morally good actions without the concept of habits as persistent tendencies enabled by grace. This limitation affects the credibility of Barth's theological ethics.
