Book excerpt: This book is designed for college and High School age students who are considering work as missionaries in foreign countries. It is the result of 30 years work as a consultant to American students and volunteers who wish to provide spiritual and humanitarian services to people who face deprivation and hardships in countries listed as '3rd world countries'. The secondary purpose of this book is to present the authors view that American people should not see America as a nation, with its political and social values and laws as compatible with Biblical and spiritual teachings. The idea of 'Church and State' is not a Biblical concept.
