In one sense the Gospel of John is more profound than the Synoptics. It is the most difficult Gospel for most expositors to preach and to teach for reasons that will become evident as we study it. In another sense, however, the fourth Gospel is the easiest Gospel to understand. Leon Morris wrote that it is a pool in which a child can wade and an elephant can swim.28It is both simple and profound. It clarifies some things that the Synoptics leave as mysteries.
What are these mysteries? Matthew presents Jesus as the King, but it does not articulate the reason for Jesus' great authority. John does. Mark presents Jesus as the Servant, but it does not account for His depth of consecration to God. John does. Luke presents Jesus as the perfect Man, but it does not explain His uniqueness from the rest of humankind. John does.
The Gospel of John reveals answers to the mysteries about Jesus that the Synoptics leave hidden. It is therefore an apocalypse, an unveiling similar to the Book of Revelation in this respect. The Book of Revelation is the climax of biblical Christology. The Gospel of John plays that part among the Gospels. It is a revelation of the person of Jesus Christ more than any of the others. John told us that it would be this in his prologue (1:1-18).
The statement of the message of this Gospel occurs in 1:18: "No man has seen God at any time; the only begotten God, who is in the bosom of the Father, He has explained Him."John claimed that Jesus was the explanation of God the Father. This Gospel presents Jesus as the One who manifested God to humankind. This book then stresses the revelation of the truth about God.
Mankind has constantly sought to represent God in some way. We want to know what God is like. Ideas about God that do not come from the revelation of Himself in Jesus Christ are idolatrous. They create a false view of God. Typically human beings without divine revelation have imagined God as being an immense version of themselves, a projection of human personality into cosmic proportions. God's revelation of Himself, however, involved the limitation of Himself to humanity, the exact opposite approach. This is what God did in the Incarnation. God's revelations are often the exact opposite of what one would expect.
John presented Jesus as the Son of God. He wanted his readers to view Jesus and to see God. In the tears of Jesus, we should see what causes God sorrow. In the compassion of Jesus, we should see how God cares for His own. In the anger of Jesus, we should see what God hates.
What do we learn about God from Jesus in John? The prologue gives us the essential answer, and the body of the book explains this answer with various illustrations from Jesus' ministry. The prologue tells us that Jesus has manifested the glory of God by revealing two things about Him: His grace and His truth (1:14). All that Jesus revealed about God that this Gospel narrates is contractible into these two words. Notice first the revelation of grace in this Gospel.
The Gospel of John presents God as a gracious person. Behind His gracious dealings lies a heart of love. There are probably hundreds of evidences of God's love resulting in gracious action in this book. Let us note just the evidence of these qualities in the seven signs that John chose to record.
The miracle of changing water into wine (ch. 2) shows God's concern for marital joy. The healing of the official's son (ch. 4) shows God's desire that people experience family unity. The healing of the paralytic (ch. 5) shows God's grace in providing physical restoration. The feeding of the 5000 (ch. 6) shows God's love in providing material needs. The miracle of Jesus walking on the water (ch. 6) shows God's desire that people enjoy supernatural peace. The healing of the man born blind (ch. 9) illustrates God's desire that we have true understanding. The raising of Lazarus (ch. 11) shows God's grace in providing new life. All these miracles are revelations of God's love manifesting itself in gracious behavior toward us in our various needs. These are only the most obvious manifestations of God's grace in this book.
This Gospel also reveals that God is a God of truth. Another one of God's attributes that we see revealed in this Gospel lies behind the truth that we see revealed in this Gospel. That attribute is His holiness. The figure that John used to describe God's holiness is light. Light is a common figure for God's holiness in the Old Testament too. The principle of God's holiness governs the passion of His love.
Jesus' great works in John reveal God's love and His great words reveal God's truth. Let us select seven of the great "I am"claims of Jesus as illustrations of the various aspects of the truth that Jesus revealed about God. All these claims point to God as the source and to Jesus as the mediator of things having to do with truth.
The bread of life claim (ch. 6) points to God as the source of true sustenance. The light of the world claim (ch. 9) points to God as the source of true illumination. The door claim (ch. 10) points to God as the source of true security. The good shepherd claim (ch. 10) points to God as the source of true care. The resurrection and the life claim (ch. 11) points to God as the source of true life. The way, the truth, and the life claim (ch. 14) points to God as the source of true authority. The vine claim (ch. 15) points to God as the source of true fruitfulness. All of these claims pointed directly to Jesus as the mediator, but they also pointed beyond Him to God the Father. They were revelations of the truth concerning God.
These are all further revelations of the character of God introduced first in Exodus 3 where God began to reveal Himself as "I am."The Law of Moses was an initial revelation about God. The revelation that Jesus Christ brought was a further, fuller, and final revelation of the grace and truth that characterize God (1:17). These revelations find their most comprehensive expression in the fourth Gospel.
What are the implications of the revelation in this Gospel? First, such a revelation calls for worship.
In the Old Testament, God revealed Himself and dwelt among His people through the tabernacle. In the Incarnation, God revealed Himself and dwelt among His people through His Son (1:14). The tabernacle was the place where God revealed Himself and around which His people congregated to worship Him in response. The Son of God is the person through whom God has now given the greatest and fullest revelation of Himself and around whom we now bow in worship.
Second, such a revelation calls for service. Under the old Mosaic economy, worship prepared God's people to serve Him. Their service consisted of carrying out His mission for them in the world. The revelation of God should always result in service as well as worship (cf. Isa. 6:1-8). When we learn who God is as we study this Gospel, our reaction should not only be worship but service. This is true of the church as a whole and of every individual believer in it. Thomas' ascription of worship (20:28) was only preliminary to his fulfilling God's mission for him (20:21-23). Worship should never be an end in itself. Even in heaven we will serve as well as worship God (Rev. 22:3).
As recipients of this revelation of God, our lives too should be notable for grace and truth. These qualities should not only be the themes of our worship. They should also be the trademarks of our service. Truth and holiness should mark our words and motives. Graciousness should stamp our works as we deal with people. If they do not, we have not yet comprehended the revelation of God that Jesus came to bring to His own. Sloppy graciousness jeopardizes truthfulness, and rigid truthfulness endangers graciousness. Jesus illustrated the balance.
This Gospel has a strong appeal to the unsaved as well. John wrote it specifically to bring the light of revelation about Jesus' true identity to those who sit in spiritual darkness (20:30-31). The knowledge of who Jesus really is is the key to the knowledge of who God really is. Therefore our service must not only bear the marks of certain characteristics, namely grace and truth, but it must also communicate a specific content: who Jesus is. People need to consider who Jesus is. There is no better way for them to do this than by reading this Gospel. Remember the stated purpose of this book (20:30-31). Use it as an evangelistic tool.
