Question: What did the Apostle John mean when he warned that "many antichrists have come"? What is an antichrist?
Answer: To understand the term "antichrist"—which is found only in 1 John and 2 John, it is helpful to examine the scriptures that use the term. The phrase "many antichrists" occurs in 1 John 2:18: "Little children, it is the last hour, and as you have heard that the Antichrist is coming, even now many antichrists have come, by which we know that it is the last hour."
