This book will always have a special place in my affections. It was loaned to me by a Christian friend/co-worker when I was still an ignorant (college grad) unbeliever. It answered many of my questions about Bible prophecy, including many I never considered. It is an excellent popular level treatment of pre-tribulational premillenialism (the same theological background of the "Left Behind" series). The insight Lindsey displays about the "near future" was amazing (look at the publication date and what has transpired since). Recommended for anyone who wishes to understand pre-trib, premillenialism.
I must have owned 5 copies of this incredible book over the years. Each copy, dog-eared and marked up, has been "borrowed" and never returned, doing God's work in the world. The Late Great Planet Earth is a classic eye-opening look at biblical prophecy. It initiated the "Jesus Freak" generation of the early 1970s into deeper spiritual issues.
