John's presentation of Jesus in his Gospel has been a problem to many modern students of the New Testament. Some regard it as the greatest problem in current New Testament studies.15Compared to the Synoptics that present Jesus as a historical figure, John stressed the deity of Jesus. Obviously the Synoptics present Jesus as divine also, but the emphasis in the fourth Gospel is more strongly on Jesus' full deity. This emphasis runs from the beginning, with the Word becoming flesh (1:1, 14), to the end, were Thomas confessed Jesus as his Lord and God (20:28). John's purpose statement (20:30-31) explains why he stressed Jesus' deity. It was so his readers would believe that He is the Christ, the Son of God, and thereby have eternal life.
The key word in the book is the verb "believe"(Gr. pisteuo), which appears 98 times. The noun form of the word (Gr. pistis, "faith") does not occur at all. This phenomenon shows that John wanted to stress the importance of active vital trust in Jesus. Other key words are witness, love, abide, the Counselor (i.e., the Holy Spirit), light, life, darkness, Word, glorify, true, and real.16These words identify important themes in the Gospel.
John's unique purpose accounted for his selection of material, as was true of every biblical writer. He omitted Jesus' genealogy, birth, baptism, temptation, exorcizing demons, parables, transfiguration, institution of the Lord's Supper, agony in Gethsemane, and ascension. He focused on Jesus' ministry in Jerusalem, the Jewish feasts, Jesus' private conversations with individuals, and His preparation of His disciples (chs. 13-17). John selected seven signs or miracles that demonstrate that Jesus was the divine Messiah (chs. 2-12). He also recorded the discourses that Jesus gave following these signs that explained their significance. Moreover he stressed Jesus' claims that occur in the unique "I am"statements (6:35; 8:12; 10:7, 9, 11, 14; 11:25; 14:6; 15:1, 5).
About 93% of the material in John's Gospel does not appear in the Synoptics.17This fact indicates the uniqueness of this Gospel compared with the other three and explains why they bear the title "Synoptic"and John does not. All four Gospels are quite similar, though each of them has its own distinctive features. John, on the other hand, is considerably different from the others. Specifically it stresses Jesus' deity stronger than the others do. It is, I believe, impossible to determine for certain whether or not John used or even knew of the Synoptic Gospels.18I suspect that he did.
Another difference between the Synoptics and the fourth Gospel is the writers' view of eschatology. They all share the same basic view, namely that the Jews' rejection of their Messiah resulted in the postponement of the messianic kingdom. However the Synoptic writers stressed the future aspects of eschatology more than John who put more emphasis on the present or realized aspects of eschatology. This is not to say that John presented the kingdom as having begun during Jesus' first advent. He did not. He did stress, however, the aspects of kingdom life that Christians currently enjoy as benefits of the new covenant, which Jesus ratified by His death. These include especially the Holy Spirit's ministries of indwelling and illuminating the believer. Such a shift in emphasis is understandable if John wrote later than the other Gospel evangelists. By then it was clear that God had postponed the messianic kingdom, and believers' interest was more on life in the church than it was on life in the messianic kingdom (cf. chs. 13-17).
"It is . . . quite possible that one of John's aims was to combat false teaching of a docetic type. The Docetists held that the Christ never became incarnate; everything was seeming.'19That the docetic heresy did not appear in the first century seems clear, but certain elements that later were to be embodied in this heresy seem to have been quite early."20
"We have suggested that the Fourth Gospel was addressed to two groups within the Johannine community, each of which represented an extreme interpretation of the nature of Jesus: one which did not accept him as God, and the other which did not accept him as man (see the introduction, xxiii; also Smalley, John, 145-48). The perfectly balanced christology of the Fourth Gospel was intended, we believe, to provide a resolution of this theological crisis: to remind the ex-Jewish members of the group, with their strong emphasis on the humanity of Jesus, that the Christ was divine; and to insist, for the benefit of the ex-pagan members (with their docetic outlook), that Jesus was truly human."21
The context of Jesus' ministry accounts for the strong Jewish flavor that marks all four Gospels. Yet John's Gospel is more theological and cosmopolitan than the others.
"It has . . . a wider appeal to growing Christian experience and to an enlarging Gentile constituency than the others.
"The Synoptics present him for a generation in process of being evangelized; John presents him as the Lord of the maturing and questioning believer."22
As a piece of literature, John's Gospel has a symphonic structure.
"A symphony is a musical composition having several movements related in subject, but varying in form and execution. It usually begins with a dominant theme, into which variations are introduced at intervals. The variations seem to be developed independently, but as the music is played, they modulate into each other until finally all are brought to a climax. The apparent disunity is really part of a design which is not evident at first, but which appears in the progress of the composition."23
Tasker described the fourth Gospel as "the simplest and yet the most profound of the Christian Gospels."24
