What the Bible says about Revelation, Authorship of
(From Forerunner Commentary)
The apostle John identifies himself as the human author and witness of the Revelation three times in the first nine verses (verses 1-2, 4, 9). He humbly calls himself God's "servant" (doulos, "bond-slave"), not even titling himself an apostle. In verse 9, he adds that he is "both your brother and companion in tribulation and the kingdom and patience of Jesus Christ." He claims no special prominence or distinction; in his own mind, he is just a "regular guy" enduring the same trials in his walk to God's Kingdom as any other Christian. These few details are surprisingly more information than John normally includes about himself in either his gospel or his three epistles.
Traditionally, the book of Revelation has been ascribed to the apostle John, son of Zebedee (Matthew 4:21), "the disciple whom Jesus loved" (John 21:20; 13:23; 20:2), and no creditable argument has been put forward to dispute his authorship. When it was written about AD 95, he would certainly have been a very old man, but by all accounts, the apostle John lived to be nearly 100 years old, dying a peaceful death in the area of Ephesus sometime during the reign of the Roman emperor Trajan (AD 98-117).
