As one of the greatest Christian philosophers of the 20th century, Francis Schaeffer made it his mission to relate Christianity to the surrounding culture’s worldview. To Schaeffer true spirituality is not a mechanical process like some sort of to-do list, but an active experience—informed by the truth of what God has said in his word. Through the pages of this book, a new generation of readers will uncover what true spirituality is and how to experience it in their own lives—moment-by-moment communion with God himself, grounded upon Christ’s finished work on the cross.
