Well-being is a familiar term in academic literature and public discourse. It captures the imagination by addressing issues related to the social good and the quest for personal happiness. It embraces a wide variety of concerns: age, gender, sexuality, ethnicity, self-esteem, health, class, education, institution and ecosystems, among many issues. Well-being studies focus on the welfare of the world and its inhabitants, bringing holistic and transformative perspectives to bear. The Christian faith has been a powerful contributor to this tradition over the centuries. Human beings, made in the image of God, are called to live transformed lives through the Spirit of Christ in communities of grace and reconciliation for the benefit of others, caring for our planet in the expectation of God's new creation. What difference does the study of well-being from a Christian perspective make?
