The field of life span development in psychology has much to offer those engaged in making disciples, and Chris Kiesling brings those insights to bear in this volume. He appropriates the most useful observations from this discipline in light of biblical teaching. Drawing on more than twenty-five years of experience teaching faith development topics in academic and local church settings, Kiesling assembles a toolkit that will help those in ministry think comprehensively about discipleship at every stage of life. Taking into account physical, cognitive, emotional, and social aspects of human development from infancy through older adulthood, Kiesling guides readers in making practical use of these insights in churches and educational settings. Pastors, ministry leaders, and educators will benefit from this treatment, which brings cutting-edge findings from the social sciences into dialogue with Scripture, theology, and practical ministry.
