This book is an easy read and gives a great overview the Kingdom of God. Terms like Kingdom of God, Kingdom of Heaven, and Gospel of the Kingdom have been interpreted differently by many different theologians, but Dr. Ladd unifies these terms and gives a wonderful explanation of what it meant back in the time of Christ and what it's ramifications are today. While he is a little more literal in his interpretation than I might be (today he probably would fall into a progressive dispensationalist framework), the book overall is a wonderful summary of what it means to be part of the kingdom of God.
The chapter on kingdom righteousness was both informative and exhortational. His breakdown of Matthew 5-8, although short, was direct and really helped me to understand what Christ was saying in a way that much longer books haven't.
The last chapter on "When will the kingdom come in fullness?" is a great challenge to evangelism.
Overall, I'd give this book a 4 out of 5. The only detractors are a) he's a little to literal and b) some of his statements aren't explained and proven to the extent that I'd like. But those are both just personal preferences. Great book - a great primer on the kingdom of God.
