St. Josemarí a preached emphatically that God calls us all to the fullness of Christian life that is holiness while simultaneously and passionately loving the world in which we live. He liked to say that, with Opus Dei, God had " opened up the divine paths of the earth." In other words, God invites men and women of all walks of life to seek holiness as members of Opus Dei. Some are young and others old, some married and others single. Among them are brick layers and college professors, entrepreneurs and civil servants. They share a common belief that God wants them to seek holiness by living the spirit of Opus Dei in the midst of the world, and by trying to bring their colleagues, friends and relatives closer to God. In everything else in their lives, they vary greatly. In this book, you will meet a handful of these men and women, ranging from an American plumber to a Swiss philanthropist and from a Spanish teenager with cancer to a Guatemalan pediatrician who first learned about Opus Dei when he was already fifty-four years old. In these stories, may we all be encouraged and inspired to live a life of deep faith, committed to our call to holiness through the means God has given us.
