In his book "The Power That Changes the World," Bill Johnson emphasizes the significance of recognizing and valuing God's calling in every person's life, regardless of their profession. He suggests that individuals, whether they are dentists, lawyers, housewives, or mechanics, are divinely appointed to fulfill their roles. Each vocation offers an opportunity to reflect God's character and contribute positively to society.

Johnson argues that by acknowledging these callings, we enhance the overall health of our communities. The essence of this message is to appreciate the diversity of callings and understand that they collectively serve a higher purpose, enriching both individual lives and society as a whole.
