John

John was perhaps the youngest disciple of Jesus, and along with his brother James and with Peter was one of the “inner circle” of disciples. He and James, known as “the sons of Zebedee,” were fishermen called into discipleship by Jesus, who nicknamed them the “sons of thunder” because of their zeal, which sometimes got the best of them (Matthew 20:20-28; Luke 9:51-56). John, along with Peter, played a big part in the development of the early church in Jerusalem and most likely spent much of his ministry there. It is believed that later in his life he served as an elder in the city of Ephesus because of his being sentenced to exile on the island of Patmos. It was there that he wrote the last book of the Bible, Revelation.
