The purpose of John's writings is to uplift us and show us a revelation of mysterious, divine things.

约翰一章十四节说，成了肉体并支搭帐幕在我们中间的话，丰丰满满的有恩典，有实际，门徒也见过祂的荣耀。我们把十四节和一节、四节摆在一起，就有话、神、生命、光、肉体、帐幕、恩典、实际（真理）和荣耀。然后在约翰一章二十九节有羔羊：“看哪，神的羔羊，除去世人之罪的！”你能领会这一切奥秘的事么？话怎么会是神，话里的生命怎么会是人的光？美妙的神自己怎么会成为肉体，成为肉体的神，在肉体里的神，怎么会是帐幕？这帐幕怎么会丰丰满满的有恩典，有实际？不仅如此，这样成为肉体的一位，怎么也是神的羔羊？谁曾想像过，在人类历史上会有一本著作包含这样的事？这本著作，就是约翰福音，告诉我们那是永远的话，并且就是神的那一位；又告诉我们，在这话里有生命，这生命就是人的光，祂成了肉体，祂在肉体里就是帐幕，当我们来到这帐幕，我们就接受恩典和真理，并享受祂的荣耀，并且这样美妙的一位也成了羔羊。像这样的著作不仅仅是属人的，也不是宗教、道德、伦理或哲学的著作，乃是包含完全神圣之启示的著作。

许多新约读者喜爱路加福音，因为其中有许多的比喻，也陈明得救罪人的事例。然而，也许我们喜爱路加，是因我们的眼光有限，像井底之蛙一样。井底之蛙只能看到一小圈的天空。但在约翰所写的五卷书里，整个天都向我们揭示了。当我们看到约翰著作中的启示，我们就被拔高，离开我们的“井”。

John 1:14 says that the Word that became flesh and tabernacled among us was full of grace and reality, and also that the disciples beheld His glory. When we put verse 14 together with verses 1 and 4, we have the Word, God, life, light, flesh, tabernacle, grace, reality (truth), and glory. Then in John 1:29 we have the Lamb: "Behold, the Lamb of God who takes away the sin of the world!" Are you able to understand all these mysterious things? How can the Word be God, and how can the life in the Word be the light of men? How can the wonderful God Himself become flesh, and how can the incarnated God, God in the flesh, be the tabernacle? How can this tabernacle be full of grace and reality? Furthermore, how can such an incarnated One also be the Lamb of God? Who would ever imagine that in human history there could be a writing containing such matters? This writing, the Gospel of John, tells us of One who is the eternal Word and the very God, and tells us that in this Word there is life, that this life is the light of men, that He became flesh, that in the flesh He was the tabernacle, that when we come to this tabernacle we receive grace and truth and enjoy His glory, and that such a wonderful One also became a Lamb. A writing such as this is not merely human, and it is not something religious, moral, ethical, or philosophical. This is a writing containing a revelation that is altogether divine. 

Many readers of the New Testament love the Gospel of Luke because it has many parables and presents the cases of sinners who are saved. However, we may love Luke because our view is limited, like that of a frog in a well. A frog in a well can see only a small circle of sky. But in the five books written by John the entire heaven is unveiled to us. When we see the revelation in the writings of John, we are lifted out of our "well".
