Rather than waste too much time trying to understand dispensationalists without first grasping what is promised for us, please take the time to read and study through the book of Revelation (that's the last book of the New Testament for those who might not know) before you invest in this book. From my perspective, I found this book to be a slanted, liberal useless waste of time written by someone who must be questioning their faith and/or does not believe the Bible to be the inspired word of God.
