Explanation: The Gospel of John is one of the four Gospels of the New Testament, the fourth in a row. While the first three Gospels together form a whole, the fourth Gospel of John is a whole unto itself. One of the verses that can be read in John's Gospel is the words of Christ himself who said that he, the Christ, is the way, the truth, and the life. So it could be said that the overall story of Christ's coming and his mission is in fact the story of God's incarnation, when the Son of God himself came as a man and offered salvation to all who believe in him. This means that John's intention while writing the Gospels was to testify that Jesus Christ is indeed the Son of God in the flesh, for the Son (the Word) became flesh and settled and showed himself among his people, to offer them salvation.
