Why was John's Gospel so different from the synoptic Gospels?

I believe John wrote his gospel after the synoptic gospels were written. He intentionally avoided repeating much of the synoptic material.

Jn 20:

30 Jesus performed many other signs in the presence of his disciples, which are not recorded in this book. 31 But these are written that you may believe that Jesus is the Messiah, the Son of God, and that by believing you may have life in his name.

John chose his stories for his particular purposes.

Jn 21:

24 This is the disciple who testifies to these things and who wrote them down. We know that his testimony is true. 25 Jesus did many other things as well. If every one of them were written down, I suppose that even the whole world would not have room for the books that would be written.

John’s Gospel was different because it served a different purpose. He was not merely trying to introduce Jesus; rather, he sought to unveil Jesus' glorious identity. The Synoptic gospels described the events. John sought to describe other events and to give them theological depth through the same Jesus.

Jn 1:

14 The Word became flesh and made His dwelling among us.b We have seen His glory, the glory of the one and only Son from the Father, full of grace and truth.

John structured his gospel around seven powerful "I am" statements, where Jesus directly revealed his divine identity and purpose:

1. "I am the bread of life." (John 6)
2. "I am the light of the world." (John 8)
3. "I am the gate for the sheep." (John 10)
4. "I am the good shepherd." (John 10)
5. "I am the resurrection and the life." (John 11)
6. "I am the way and the truth and the life." (John 14)
7. "I am the true vine." (John 15)

These were not just metaphors; they were claims to be the ultimate source of life, sustenance, and salvation—a role only God could fill. "Before Abraham was, I am" (John 8:58).

John wrote his Gospel to emphasize that Jesus is the great I-Am.
