What does it mean to psychologically, socially, and spiritually develop? While the question of why we develop remains speculative, the question of how is surprisingly approachable. Within the various fields of human development and contemplative spiritual traditions, we can identify four shared developmental phases. As a general model, we must meet these four criteria to progress to a new developmental stage: mastery, crisis, insight, and catalysis. Examples are given in the context of identity development (who is “me”?) as well as worldview development (specifically, how we read scripture). Applications are explored in the contexts of marketing strategy, coaching/mentoring, and spiritual direction.
