Nonetheless, this book of Schaeffer's was one of hope. This hope was born of a certainty that the Christian worldview is the only rational one, the one that best explains reality, is most logically consistent, best promotes practical consequences, and alone provides meaning and purpose. His book, then, was (on one level) a somewhat dispassionate account of how this uniquely rational worldview has come to be lost (in the culture at large). In the concluding Note, he wrote,
Christians do not need to be in the majority to influence society(that is, to bring to bear on society this forgotten worldview). Schaeffer’s life proved this, and served as a shining example of how clear worldview thinking and love of fellow humans can make a follower of Christ salt and light even in this postmodern generation.
