The focus of John's writings is the mysteries of the divine life.

[jidong xiao]

约翰著作的中心乃是神圣生命的奥秘。他福音书的中心，乃是在耶稣身位里，神圣生命显现的奥秘。生命是看不见的。然而按约翰福音，神圣的生命有形有体的显现在耶稣的人位里。这乃是个奥秘。

约翰的书信，特别是约翰一书的中心，乃是信徒与神并彼此之间所显现之神圣生命交通的奥秘。这交通是奥秘的。我们的种族、肤色、国籍虽然不同，却同样享受显现出来之神圣生命里的那一个交通。我们中间有着奇妙的一。这乃是神圣生命交通的奥秘。

The focus of John's writings is the mysteries of the divine life. In his Gospel the focus is the mystery of the manifestation of the divine life in the Person of Jesus. Life is invisible. Nevertheless, according to the Gospel of John, the divine life was manifested solidly, bodily, in the Person of Jesus. This is a mystery. 

In His Epistles In John's Epistles, especially in the first one, the focus is the mystery of the fellowship of the manifested divine life among the believers with God and with one another. This fellowship is mysterious. Although we are of different races, colors, and nationalities, we enjoy the one fellowship in the manifested divine life. We have a wonderful oneness among us. This is the mystery of the fellowship of the divine life.
