The Message of the Cross, Dr. Jaerock Lee's representative book, became a must read for all people in the world. Countless letters of thanks have been constantly received from the servants of the Lord and the believers who received grace through the book. Pastors have made requests that the book be translated in their languages saying they want to use the book for their ministry, because it delivers core messages for a proper Christian life.

The Vietnamese edition was published in April 2011, and as of June of 2011, it is now published in 22 languages: Korean, English, Chinese (Simplified and Traditional), French, Russian, Spanish, German, Japanese, Tagalog, Arabic, Vietnamese, Estonian, Urdu, Italian, Indonesian, Tamil, Hindi, Thai, Finnish, Hebrew, and Nepali. So far it has been translated into sixteen languages including Greek and Portuguese and is now being translated from English into ten languages such as Armenian and Iranian.

The book includes answers to many believers' questions on the message of salvation and the human cultivation such as 'Why did God place the tree of the knowledge of good and evil in the Garden of Eden?', 'Why is Jesus our only Savior?', and 'What is the meaning of Jesus' last seven words on the cross?'. If we understand them, we can realize God's providence embedded in the human cultivation. Then, we cannot help but love Him. In addition, when we gain realization about the providence of salvation, we will be amazed by His deep love and wisdom.

New York State Senator Dr. Ruben Diaz said, "I have not known such a greater minister whom God has used, with the power of miracles and also a biblical Christ-centered word, as Dr. Jaerock Lee. His book, Understanding the Message of the Cross of Jesus Christ, has shaken my life and also the entire city of New York. I do not only endorse and commend this book, but I also commend his entire ministry. This book will transform nations and will be a great injection and contribution for the entire Christian church all over the world."

Jose Ricardo, president of Nueva Vida Editorial Inc. for Spanish readers, stated, "This is the most Bible-based book I have ever read, and it has been constantly loved by many readers." Dr. Richard Blake from the U.S. wrote review of the book on Amazon.com, "The Message of the Cross provides readers with the foundation of faith by letting them understand God's measureless providence and love. His book is based on the Bible, and his message is filled with unchanging conviction on the gospel of Jesus Christ."
