John 20:19-31, Introduction to John’s Gospel (2)

DATE

It is commonly held that John’s gospel is the last of the four gospels, written between 85 and 110 AD.  Documents making reference to the Gospel have been found that date to around 120 AD, meaning it had gained a wide circulation by that time.

OCCASION

As to the set of circumstances that the Holy Spirit used to bring John to write this Gospel, after the other three had been in use for several years, we cannot be sure.  The best possible suggestion is that John wrote this work to combat the growing cult of Gnosticism.

Some Gnostics held that Christ was a man upon whom the Christ-spirit had come at His baptism, and who relinquished that spirit on the cross.  John’s emphasis on divine Sonship, the Word becoming flesh, and the ministry after the cross would have dispelled that heresy.  The same truths would have denied other Gnostic beliefs that Christ was God who “appeared” to be a man.  Christ is presented as the true God/true Man that He claimed to be.

PURPOSE

While the occasion is uncertain, John’s purpose is very clear, for he tells us in 20:31: “But these are written that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in His name.”

The little Greek term indicating purpose is found twice in this verse: 1) that you may believe; and 2) that by believing you may have life.  In other words, this Gospel is evangelistic, presenting the claims of the Lord Jesus Christ, and presenting those claims in an apologetic (persuasive) fashion.  But then this Gospel is also for growth, that the believer may come to experience the life (abundant life) that Christ offers.

Based on this statement, it seems clear that John is a Gospel especially helpful to new Christians, as well as for unbelievers.  We are familiar with ministries whose primary activity is the distribution of small “Gospel of John” booklets, trusting the Holy Spirit to minister to the unsaved as they read. 

John’s purpose is seen in the material from Christ’s life and ministry that he, by the Holy Spirit, selected.  This is seen in the miracles John selected, seven in John 1-12, then the resurrection of Christ and the miracle of the great catch of fish after Jesus’ resurrection.  The first seven, as we will see, provide pictures of the gospel and what it means to believe in Christ.  Jesus’ centrality to the gospel is also seen in several “I AM” claims of Christ (e.g. John 6:35, “I am the bread of life”).  “John” is a great resource for the presentation of the gospel!
