Critical Journey

The Critical Journey: Stages in the Life of FaithBy Janet O. Hagberg and Robert A. Guelich (Sheffield Publishing Company, Salem, WI 1989/1995/2005)
The Critical Journey examines the distinct phases of spiritual life. Though the authors readily admit that it is impossible to dogmatically define something as subjective and unique as the individual spiritual walks of people, by examining common traits and experiences they have identified six distinct "stages" in people's spiritual lives:

1. The Recognition of God
2. The Life of Discipleship
3. The Productive Life
4. The Journey Inward/The "Wall"
5. The Journey Outward
6. The Life of Love

Here's a pdf that I found on Kathy Escobar's blog.
