Schuurman draws on the Lutheran and Calvinist traditions in constructing his doctrine of vocation. In doing so, he provides biblical, theological, and ethical analysis in exploring current responses to the classic view of vocation and offers a revised statement and application of this doctrine for contemporary North American Christians. According to Schuurman, many Christians today find it both strange and difficult to interpret their social, economic, political, and cultural lives as responses to God's calling. To renew this biblical perspective Christians must recover the language, meaning, and reality of life as vocation, which (it is hoped) will inevitably lead them to experience and understand God more deeply.
