The Gospel of John 2

John’s purpose of writing is – as John 20:30-31 tells us – “Jesus did many other miraculous signs in the presence of his disciples, which are not recorded in this book. But these are written that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in his name” – What so special that Jesus is called the Son of God? What so unique about this title as applied to Jesus?
