It contains a highly schematic account of the ministry of Jesus, with seven "signs" culminating in the raising of Lazarus (foreshadowing the resurrection of Jesus) and seven "I am" discourses (concerned with issues of the church–synagogue debate at the time of composition) culminating in Thomas ' proclamation of the risen Jesus as "my Lord and my God".

The Gospel According to John develops a Christology—an explanation of Christ’s nature and origin—while leaving out much of the familiar material that runs through the synoptic Gospels of Matthew, Mark and Luke, including Jesus’s short aphorisms and parables, references to Jesus’s background, and proclamations about the kingdom of God.

John is the fourth and last Gospel (an account of Jesus’ life and ministry) in the new Testament. John focuses on the deity of Christ more so than the other four: we see Jesus as the Word of God, the Son of God, and God Himself. Jesus is a great miracle worker, an omniscient teacher, a compassionate provider, and a faithful friend.

The Gospel of John was written to prove that Jesus Christ is the Son of God. As an eyewitness to the love and power displayed in the miracles of Jesus, John gives us an up-close and personal look at Christ's identity.

The Gospel of John begins by announcing that God’s Word, which brought all things into being, became flesh in Jesus of Nazareth. During his ministry, Jesus reveals the power of God by performing seven miraculous signs, including turning water into wine, healing the sick, and raising the dead.
