The Gospel of John is a unique book. It stands apart from the other gospels (Matthew, Mark, and Luke) in that it covers details of Jesus’ life which the others do not. The events in John mostly take place in Judea, whereas the other gospels focus on Galilee. John is also different in how it begins. John immediately starts with the divinity of Jesus Christ.

In the beginning was the Word, and the Word was with God, and the Word was God. 2 The same was in the beginning with God. 3 All things were made by him; and without him was not any thing made that was made. (John 1:1-3)

The “Word” is John’s designation for Jesus. This is consistent throughout his New Testament writings (1-3 John and Revelation). It emphasizes Jesus as the incarnate Word of God. And when Jesus speaks, it is literally God speaking.
