Henri Nouwen is internationally acclaimed as one of the most beloved and important spiritual writers of the second half of the twentieth century, yet little has been written on Nouwen's own mentors, especially on those who influenced him the most: Thomas Merton, Vincent Van Gogh, Jean Vanier and Rembrandt Van Rijn.

Nouwen encountered Merton in May, 1967. He began to learn about the art and writing of Van Gogh in 1975. He met Vanier in 1981. The painting of the Prodigal Son Nouwen came across in 1983.

Touched by God's Spirit brings these four masters of the spiritual life together and their significant contribution, notably, to compassionate Christian living as expressed by Nouwen is studied in depth.
