Developing a Christian Worldview of Spiritual Formation and Growth Liberty University Abstract This paper looks at how spiritual formation and growth can develop through a person’s lifetime. The goal is to show how modern day human development theories relate to Christlike living. Erikson’s developmental theory and Kohlberg’s moral development theory both give a guide to maturity in a secular worldview. By looking at Jesus’ Sermon on the Mount‚ we can see God’s directions to living a Christlike
