John writes with one particular idea in mind. He wants to prove to the reader that Jesus is God's way of saving humans from the terrible problem of sin or "evil". John starts by telling the reader that Jesus was and is God. John says that Jesus is God's "Living Communication" (or "Living Word"). Every part of "John's Gospel" is written to show that Jesus came from God, taught the "Message of God" and is the way for people to understand "God's Love".
