Okay kiddo, do you know what the antichrist is? It's someone in the Bible who's really, really bad. Like, even worse than the bad guys in your favorite movies.
Well, people who write about God and religion, also known as ecclesiastical writers, have talked about the antichrist too. They think that this bad guy will come back one day and try to lead people away from God.
These writers often refer to the antichrist in their books and sermons. They believe that he will do a lot of bad things, like deceive people, spread lies, and cause trouble all over the world.
But don't worry too much, because they also believe that in the end, God will defeat the antichrist and everything will be okay again. So, it's important to be good and stick with God, even if the antichrist tries to trick you.
