The divide between the sacred and the secular life has dogged Christians for centuries. Even today, many Christians and church leaders still assume that the workplace is inferior to pastoring, Bible study, mission trips, and the like. This volume provides a different approach: it surveys the persistence of the sacred-secular divide in Christian history to develop a more robust theology of vocation while engaging with both the Old and New Testament. Charles offers a vision for numerous ways Christians are called to live faithfully in the so-called secular world.
