The book of Isaiah depicts for its readers what happens when Isaiah volunteers to become Yahweh's gofer--when he acts and speaks on Yahweh's behalf with Yahweh's authority. Goldingay unfolds the voices and messages of those prophetic actions and experiences. While doing this he points out that three attributes of Yahweh come into distinctive focus in Isaiah: Yahweh's majesty and authority, Yahweh's passion in anger and compassion, and Yahweh's insight and capacity to formulate a plan and put it into effect. Goldingay also examines the way Isaiah thinks about the people of God and the relationship between the vision of who they could be, the reality of who they were, the calamity of that contrast, and ultimately the promise Yahweh offers to them.
