The reality of the West's post-Christendom, multiethnic, multicultural context has meant that, more than ever, Christians face questions posed not simply by the existence of other religions, but also by their apparent flourishing. If secularization is alive and well, then so too is society's sacralization. Hence, a theology of religions is arguably the most significant concern confronting Christian mission and apologetics in the twenty-first century. There has been little evangelical theology offering a detailed, comprehensive, and biblically faithful analysis not only of the question of salvation but also questions of truth, the nature and history of human religiosity, and a host of other issues pertaining to Christian apologetics and contextualization amid religious pluralism. In Their Rock is Not Like Our Rock, lecturer and vice principal of Oak Hill College in London, Daniel Strange, explores these issues and offers the beginning of a theology of other religions.
