Book excerpt: Facet by facet this internationally acclaimed Christian thinker examines life and the universal search for its meaning. What is "the call"? Far bigger than our jobs, deeper than our personal accomplishments, higher than our wildest ideas of self-fulfillment, our "calling" addresses the very essence of our existence. Discovering it in times past has changed whole nations and cultures. It could do the same to ours. A classic reflective work in the tradition of C. S. Lewis and Oswald Chambers, now ready to challenge the latest generation of high school and college graduates.
