Ryrie's Dispensationalism, Revised and Expanded, is well worth the time and money. Anyone who wishes to understand Dispensational Premillennial Theology, Covenant Theology, Progressive Dispensational Theology, and Ultra-Dispensational Theology and how they relate to "rightly dividing the word of truth", needs to purchase this book.
I remember the late J vernon Mcgee say that Dispensationalism was the greatest blessing to him after salvation. Well may I say friends that this book is the greatest blessing to dispensationalism. This is a positive presentation of dispensational theology at its best by an American theologian. It is written in such a clear style such that the novice and the seasoned theologian can both read and profit from it.
Dr. Charles C. Ryrie wrote this gem, even added new material for the revised edition. Chuck's the Boss when it comes to Dispensationalism leaving the people who dislike Dispensationalism sad and alone by themselves. For them, it's all over but the cryin'.
Look: the book explains what I need to know. Gives the pros and the cons. All you folks who think the Body of Christ is going to be in the Tribulation, well, you keep thinking that and lemme know how it works out for ya.
Ryrie Rules - the others merely drool. 'Nuff said.
