For more than forty years, Robert E. Coleman's bestselling The Master Plan of Evangelism has been the standard in evangelism literature. But what is the theology behind evangelism? And why is it important for Christians to understand? The Heart of the Gospel offers a systematic theology of evangelism that will ground and inform our practice of spreading the Good News. Each chapter covers a major biblical doctrine, explains its various evangelical interpretations, treats misconceptions that adversely affect evangelism, and offers practical applications of the doctrine. Based on decades of classroom teaching, this comprehensive work is aimed at ministry readers interested in evangelism and outreach.
