When the early Christian author Tertullian asked what Jerusalem has to do with Athens, he could not have anticipated the intellectual, cultural, and social challenges facing Christians in the twenty-first century. But his question is no less relevant today. What does life in Christ have to do with the stuff of our daily lives—our work, education, citizenship, and behavior? What are we on earth to do? In this wide-ranging collection, J. Daryl Charles shares insights from nearly thirty years of reflecting on these and related questions. Wisdom's Work explores the earthiness of the Christian life through essays on vocation, work, ethics, education, and the calling of believers to be salt and light in the world—the real world that we inhabit every day.
