The author does not, in fact, answer the question posed in the title, but he does provide an in-depth analysis of all the Biblical references to the Antichrist and a discussion of what they might mean. His interpretations are dependent on his own belief in the rapture scenario widely accepted in America, though he does set out the views of others who believe differently and explains why he does not agree with them. He has evidently written twenty other books on the end-times, so has put a great deal of thought and research into his subject, and this is not a light read, though neither is it unreadably abstruse. Divided into sections covering curiosity, character, coming, career and consummation (as you can tell, he is also a pastor!) he uses Bible prophecies to debunk many modern speculations about the Antichrist and the meaning of the number of the beast. Always interesting if not always entirely convincing, it will at least send the reader to search the relevant scriptures and make up their own minds as to what they think.
