FootnoteJohn, who calls himself the "disciple whom Jesus loved" (John 13:23 20:2), and who leaned against Christ's bosom at His "last supper", was one of the original twelve disciples of Jesus. He was one of the two "sons of thunder" of his father Zebedee (Mark 3:17), the other being James, another of the disciples of Jesus. The purpose of the book is stated in John 20:30-31 - "And many other signs truly did Jesus in the presence of his disciples, which are not written in this book. But these are written, that ye might believe that Jesus is the Christ, the Son of God; and that believing ye might have life through his name." John's gospel focuses on the words of Jesus more than His deeds, and highlights the deity of Jesus.
