One might see in the synoptic gospels an exhortation to understand the Jesus was the Jewish Messiah.However, one might see in the gospel of John a different emphasis.
If written around 90AD, the temple in Jerusalem would have been destroyed for 20 years. There would be no expectation of an immanent return of Jesus to establish the kingdom as had been expected by the disciples (Acts 1:6).
It is conjecture, since we are not told in the gospel, however, it might not be unreasonable to think that what makes the gospel of John distinct is that it was written for second and third generation believers distant in both time and place from the events described.
In this way the gospel of John would be more resonant with contemporary believers as we also are removed from the events described.
A purpose for the Gospel of John
Re: A purpose for the Gospel of John
The purpose for the Gospel of John is the prove conclusively that Jesus is the Son of God and that all who believe in Him will have eternal life,
The key verse that says is in John's own words is 20:31 - "But these are recorded so that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in his name."
