Being at Home in the World is a book of Christian Apologetics. But Mark McLeod-Harrison and Phil Smith don't defend Christian faith; instead, they invite readers into faith. In the course of making this invitation, the authors raise suspicions against modern naturalism, offer respectful criticisms of major religions, and explain how Christian beliefs provide an organizing center of a flourishing human life. Their invitation to Christian faith is philosophically sophisticated, but it is also honest and personal; McLeod-Harrison and Smith tell their own stories of how they grew up as Christians and why they remain believers.
