A primer is a small introductory book on a subject. A Primer on Dispensationalism was written for two groups of Christians: those new to Dispensationalism as a theology; those who have heard Dispensationalism is new and not biblical.
There are many books on dispensational history and theology. I've written some of those books. But through extensive interaction with many Christians of both Reformed and Dispensational beliefs, I perceived a need for a simpler work, a "primer," that will explain dispensational theology as briefly and as simply as may be possible. This book aims to meet that need.
A Primer on Dispensationalism defines Dispensational theology, explains the four distinctives of Dispensationalism, presents a brief history of Dispensationalism from the times of the early church fathers, and lists resources for further study.
If you want to understand the basics of Dispensationalism, or have a friend who should understand, this is the book.
