The Bible s Missionary Message Part I Old Testament is the first of three volumes on Theology of Missions: the remaining two volumes (Parts II A & B) cover New Testament teaching. It has been written for future missionaries, their friends, pastors, supporters and church members.Although these volumes are study books, they have been written in easy-reading language, in an attempt to make it useful to laymen with a good command of English. Many theological and missiological concepts are being explained from the Bible, in day-to-day language instead of professional jargon.It can be used in personal study, in classrooms, at missionary conferences, pastor s retreats, etc. It has been designed for modular teaching at Bible Schools, Missionary Training Institutes, Seminaries, etc. In intensive courses one book can be taught in about a week with 25-30 hours of teaching. If time allows, a slower pace is advised.It is the author s desire that these volumes may eventually produce much more missionary-sending activity from the Church, so that the unreached and least-reached people groups of this world may receive the gospel of Jesus Christ in the shortest possible time.
