"Eschatology" comes from two Greek words concerning "study of last things" or how things will end.  It is a general topic with many facets and is the source much excitement, confusion & controversy.  My adult "Christian experience" began with Hal Lindsey's "The Late Great Planet Earth," but studying Scripture led me to adjust my earlier beliefs a good bit.  These studies are intended to convey what I found in Scripture that led me to question much of what continues to be popularly believed on these topics.
