Nursing is a ministry of compassionate care for the whole person, in response to God's grace toward a sinful world, which aims to foster optimum health (shalom) and bring comfort in suffering and death for anyone in need. In the newly revised and expanded Called to Care: A Christian Worldview for Nursing, Judith Allen Shelly and Arlene B. Miller, asserts that nursing is a vocation, giving nurses a framework for understanding their mission and living out their calling: service to God through caring for others.
