The author takes us through the Bible, showing us how God created a perfect world and will one day return creation to its perfect glory. But for now "he has invited his human creatures to join him in this task {setting the world right} and in the new world it will eventually create. They do this by trusting in and following God's great King, Jesus, and by living in the power of the Holy Spirit. There is no better way to be the human being God created each of us to be."
The book is theology made understandable for all of us.
