The design of John's Gospel

“Jesus did many other miraculous signs in the presence of His disciples, which are not recorded in this book. 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.” John 20:30-31
This verse in John gives us a glimpse as to why his Gospel is so different to those of Matthew, Mark, and Luke (the ‘Synoptic gospels’). Rather than recording an historical account of Jesus’ life and ministry, John’s gospel has a purpose: that whoever reads it might believe that Jesus is the Christ. Therefore, the events and discourses that John records have been carefully chosen to present this fact.
John’s gospel features seven miracles and seven discourses linked to those miracles. They are as follows:
Miracle 1. Turning water into wine (John 2:1-11). Jesus reveals His glory (John 2:11).
Discourse 1. Speaking to Nicodemus about being born again (John 3:1-21).
Discourse 2. Speaking to the woman at the well (John 4:1-42). Jesus demonstrates His prophetic gift (John 4:19).
Miracle 2. Healing the son of the royal official (John 4:43-54).
Miracle 3. Healing the lame man at the pool of Bethesda (John 5:1-15).
Discourse 3. Jesus does the Father’s work, which testifies of Himself (John 5:16-47).
Miracle 4. Feeding the 5,000 (John 6:1-15). Jesus provides for those who are hungry.
Miracle 5. Walking on water (John 6:16-21). Jesus has power over creation.
Discourse 4. Jesus the bread of life (John 6:25-71).
Discourse 5. Jesus the Son of His Father (John 8).
Miracle 6. Healing a man born blind (John 9). Jesus gives sight to people, so they can follow Him.
Discourse 6. Jesus the good shepherd and the gate for the sheep (John 10).
Miracle 7. Raising Lazarus from the dead (John 11). Jesus has power over death.
Discourse 7. To His disciples, concerning His death and the promise of the Holy Spirit (John 14-16).
