We live in a post-Christian world. Contemporary thought--claiming to be "progressive" and "liberating"--seeks to undermine biblical Christianity, but in fact contradicts culture itself by assaulting family, community, authority, and nature. Today's Christians need to understand the underlying worldviews of the post-Christian culture in order to navigate these new challenges in their world. This insightful book charts the course of how postmodernism led to our post-Christian times; explores how Christians can combat today's constructivism, relativism, and Gnosticism; and offers solutions to those problems as a way to recover reality, rebuild culture, and revive faith.
