Known as the “disciple Jesus loved,” he was also a part of the inner three. (John 3:23) He wrote a large portion of the New Testament—The book of John, 1, 2, and 3 John, and the book of Revelation. He wrote more about love than any other New Testament author. His close proximity to Jesus taught him much about love.
He was exiled to the island of Patmos under Domitian, but after his death, John was allowed to return to Ephesus where he governed churches in Asia until his death in about A.D. 100.
