Among the Gospels, John's is unique. Its structure carries long conversations and extended debates, much of its content is found nowhere else, and the relationship of Jesus to the Father and his teaching on the Holy Spirit are given particular prominence.

Faith - believing in Jesus - stands at the center, with signs recorded to provoke it and accounts of individuals offered as examples of it. Colin Kruse shows how the Fourth Gospel weaves belief and unbelief into its rich Christology. The Tyndale series is concise and exegetically careful, which makes this a good first commentary on John.
