One:

In John 17:20-23 we read a part of the prayer of Jesus at the Last Supper. He pray that all who believed in Him would be one, just as He and the Father are one. Jesus tells us that this unity is essential in convincing the world that He was sent by the Father. Image the power of a Christian world totally united in Jesus Christ. This book is written in the hope that we all can abandon teachings that divided us and be united together in Christ and Christ alone.
