Why do we buy what we buy, vote the way we vote, eat what we eat and say what we say? Why do we have the friends we have, and work and play as we do? It's our choice? Yes, but there are forces, often unseen, that shape every decision we make and every action we take. These hidden, life - shaping values and ideas are not promoted through organized religions or rival philosophies but fostered by cultural habits, lifestyles and the institutional structures of society. Steve Wilkens and Mark Sanford shine a spotlight on the profound challenges to Christianity and faithful Christian living that come from worldviews that comprise the cultural soup we swim in. The authors show how to detect the individualism, consumerism, nationalism, moral relativism, scientific naturalism, New Age thinking, postmodern tribalism and salvation as therapy that fly under our radar. Building on the work of worldview thinkers like James Sire, this book helps those committed to the gospel story recognize those rival cultural stories that compete for our hearts and minds.
