The deity of Christ in the Gospel of John
The entire gospel is about how Jesus is both fully human and fully God at the same time.
John 20:31 But these are written that you may believe that Jesus is the Messiah, the Son of God, and that by believing you may have life in his name.

God was good and man was not. As a result, claiming anyone was God in the Flesh was ludicrous, or as Paul said, foolishness. It flew in the face of popular philosophy and knowledge.
