In the book The Only Necessary Thing: Living a Prayerful Life, editor Wendy Greer collects writings from Father Henri J.M. Nouwen, a Dutch-born Catholic priest. Drawn from many decades of his life, the compilation of Henri's thoughts and feelings reveal the core of the man and his belief that prayer is the only necessary thing.
The love of Jesus will give you an ever-clearer vision of your call. The more you are called to speak for God's love, the more you will need to deepen the knowledge of that love in your own heart. The farther the outward journey takes you, the deeper the inward journey must be. Only when your roots are deep can your fruit be abundant.
Henri J.M. Nouwen, author of more than 40 books, is considered one of the great spiritual writers of modern times. He taught at the University of Notre Dame, Harvard, and Yale, but shared the last seven years of his life with people with mental handicaps as pastor of l'Arche Daybreak community in Toronto.
