Book excerpt: Over the years, the Holy Father has said much about the meaning of vocation and how Catholics should respond to God's call, but it has been scattered through dozens of addresses he has given all over the world. Now at last this compact compendium collects the Pope's choicest remarks on God's call and how you should strive to hear and obey Him. He helps you clarify what God is calling you to do, explains how and when God calls, and even helps parents face up to their children's vocations!
