In 1928, Nee published a three-volume book entitled "The Spiritual Man". In February of the same year, Nee held his first "Overcomer Conference" in Shanghai. In January 1934, Nee called a special conference on the subjects of "Christ as the Centrality and Universality of God" and "The Overcomers". According to Nee, this was a turning point for him in his ministry. He said, "My Christian life took a big turn from doctrines and knowledge to a living person, Christ, who is God's centrality and universality."
