Under the amazing guidance of the Holy Spirit and the help of other believers, the author has discovered nine sets of numerical roots using James Harrison's Trinity Function or "Trinity Root Function" (TRF) as it is called in this book. And these nine roots of numbers correlate well with nine basic natural numbers from 1 to 9. Moreover, based on the concise and simple structural relationships between numbers and their corresponding roots, God's entire redemption blueprint and the core teaching of the Gospel can be presented fully at one glance. We cannot help but praise God from the bottom of our hearts for such a wonderful and amazing design On the eve of Jesus' second coming, this book is published to help all those who are willing to diligently seek the truth. On one hand, we hope the book will prevent more Christian watchmen from falling into the pit of "guessing the day and hour" of the Lord's coming; on the other hand, the book could help everyone to pay closer attention to the core teachings of the Bible and to accept Jesus as the only Savior of mankind, especially at this moment of time before His imminent return.
