Book excerpt: One of the hallmarks of LutherÕs theology was its concern for daily life. In the midst of debates about justification and salvation, church authority, and the LordÕs Supper, he bore a deep concern for daily Christian life. In this refreshing book, Mark D. Tranvik looks at the importance of vocation in LutherÕs own life and in doing so discovers renewed insights into this important doctrine. Vocation, the called life, is a way of understanding that all of life is under the care and interest of God. All of our activities as a spouse, parent, child, worker, citizen, and church member are a part of a called life. Tranvik begins the book with a clear exposition of LutherÕs context, with a focus on how the reformer actually lived out his own calling. He rapidly moves into the contemporary sphere, drawing on twenty years of teaching and interaction with undergraduate students to outline how a renewed understanding of vocation is a powerful and liberating tool for life in the twenty-first century.
