Antichrist means against or instead of Christ. The term applies to all who deny what the Bible says about Jesus Christ, all who oppose his Kingdom, and all who mistreat his followers. It also includes individuals, organizations, and nations that falsely claim to represent Christ or that improperly ascribe to themselves the role of Messiah. 1 John 2:18: "Young children, it is the last hour, and, just as you have heard that the antichrist is coming, even now there have come to be many antichrists; from which fact we gain the knowledge that is the last hour." 2 John 7: "Many deceivers have gone forth into the world, persons not confessing Jesus Christ as coming in the flesh. This is the deceiver and the antichrist." (Notice that the "many antichrists" of 1 John 2:18 are here referred to collectively as "the antichrist.") Matthew 24:24: "False Christs and false prophets will arise and will give great signs and wonders so as to mislead, if possible, even the chosen ones." The antichrist is not just one person, but many who are referred to collectively as "the antichrist." There are many other topics people have different beliefs about because of "the antichrist."
