Tom Zanzig has worked in professional ministry for more than 40 years as a director of religious education, an editor of youth ministry materials, and a publisher of adult faith formation resources. In this rigorous work, Zanzig seeks to map the nature, challenges, and delights of spiritual maturity.

After surveying the meaning and place of religion and spirituality in our times, he delves into the dynamics of transformation. He shares a mystical moment he had on a plane some 30 years ago.

Zanzig charts the different ingredients of the spiritual growth cycle which for him includes hunger and search, awakening and response, and invitations to change and grow. The author also discusses how Jesus is the embodiment of transformation and the lure of discipleship. Zanzig's affirmation of the important roles of integrity and mysticism on the Christian path makes a good case for a faith-filled and life-enhancing religion.
