This is a book about the Kingdom of God. It contrasts the values of the world, with the values of NT Christianity. The main question the author poses is this: What was the main theme of Jesus' teachings? Was it man's need for personal salvation? God's love? The new birth? God's glory? It was none of these? Jesus' main theme in His teaching (which all of these subjects were a part of) was the Kingdom of God.
The author goes on to point out the irony that this central pillar of Christ's message is almost totally missing from most of Christianity today, as a result most people do not ever fully enter into the fullness of God's will for them on earth. He makes a very convincing case that God intends for Christians to literally live out the Sermon on the Mount today; not in some distant time during the Millennium.
This book sets forth the radical life-style that Christ exemplified for us, and which His Apostles set forth in their writings, but has been obscured in all our various interpretations that practically wipe away any hint of serious commitment that God might expect of us.
The first part goes through the various values that the Kingdom holds to in variance to the world. Part 2 expounds on what the author calls "The Big Stumbling Block", which is loving our enemies. Part 3 is entitled "What is the Gospel of the Kingdom?" Part 4 "A Hybrid is born" discusses when Constantine, emperor of Rome, took control of the church, and its repercussions and lasting legacy for us today. Part 5 "When it was Illegal to be a Kingdom Christian"
This book is a "must-read" for all serious minded Christians in today's climate of mega-churches, systematic theologies, Christian soldiers etc etc.
