Why a book on missions? In the great commission (Matt. 28:18-20; Acts 1:8), believers are commanded to preach the gospel to every creature, but not all have the special calling, burden, and gifts of a missionary. It really does take a call from God to willingly give up so much and wholly devote oneself to a life of evangelism, discipleship, self-denial, faith, and love for the never-dying souls of men.There are comparatively few books on missions that strike the balance of the doctrinal, practical, and experiential, without embellishing the content to present a more polished product. The material in this book is by no means exhaustive. It is a distillation of the heart and soul of New Testament Missions from someone who has depended upon God to create, sustain, and increase a divine work, which is impossible for the flesh to do, and to provide for this same work. Cliff Hellar has written a much needed book that isolates the heart of missions work. Missionaries, and all who are interested in missions work, will greatly benefit from this book written by a seasoned veteran of 45 years as a missionary to Papua New Guinea.
