For some people, the question of their calling is very difficult to decipher; for others, it follows from an early intuition and practically unfolds of its own accord. For some, it can be the singular and exclusive direction their life takes; for others, it can change and follow new directions. Again, some people never seem to find what they are called to do; this can burden them with a continual restlessness and dissatisfaction. When you find what you are called to do, your life takes on a focus and purpose. You come into rhythm with the deeper longing of your heart.
The nature of the calling can change over time, taking a person down pathways never anticipated. The calling opens new territories within the heart; this in turn deepens the calling itself. The faces of the calling change; what at the beginning seemed simple and dear can become ambivalent and complex as it unfolds. To develop a heart that is generous and equal to this complexity is the continual challenge of growth. This is the creative tension that dwells at the heart of vocation. One is urged and coaxed beyond the pale regions into rich territories of risk and promise.
