22:18 this book. The word “book” here is the Greek biblion (in Revelation 22:19 it is biblos). This, of course, is where the “Bible” got its name. Here John warns, first of all, against adding to the prophecies given in the book of Revelation. In a broader sense, however, he would warn against adding to the Bible itself, for he was the last of the apostles, and Jesus had in effect told His apostles that He would send the Holy Spirit to bring all things to their remembrance, to guide them into all truth, and to reveal to them things to come (John 14:26; 15:26). Also, the Apostle Paul had written that the church would be “built upon the foundation of the apostles and prophets,” and that the truths of the New Testament would be “revealed unto His holy apostles and prophets by the Spirit” (Ephesians 2:20; 3:5). That “foundation” of divine revelation has been laid in the apostolic era, and thus need not be laid again. Furthermore, Paul had said that the gift of prophecy would cease once “that which is perfect [or ‘complete’] is come” (I Corinthians 13:8, 10). There can be little doubt, therefore, that John’s warning in this vitally important verse at the end of the Bible, applies to any new revelation. Both Christ and the apostles repeatedly warned against false prophets, and here—and only here—is the criterion by which to recognize such.
