My Mission of Christianity as writing an Excerpt Collection of the Holy Bible is made for numerous believers who are seeking for Truth on Earth. Due to the great amount of volumes of Old Testament, I have decided to publish it in one volume while another volume is published based on my research of New Testament. The Bible (Old and New Testaments) is completed, the most important philosophy for Chinese readers is "The Book of Changes". In this work, I have made a comparison with annotation based on these two great works "The Holy Bible" and "The Book of Changes". "The Book of Changes" can be regarded as a work with the highest level of the Chinese culture and readership on earth. It is always my mission of Christianity in leading those who are seeking for the Truth not only in "The Book of Changes" but also in the "Holy Bible". Before the main burden. May the Lord give me strength to complete this work, and to bless Him for his salvation of countless believers. Amen! This Collection contains four sections in glory of Him: (1) Summary of the Old Testament (2 parts); (2) Summary of the New Testament; (3) Summary of the Book of Changes; (4) My Interpretation of the Holy Bible and the Book of Changes.
