'Anti christ' in the Bible

Little children, it is the last hour, just as you have heard that Antichrist is Coming, and already many Antichrists have appeared; so we may be sure that it is the last hour.

Who is the notorious liar, if it is not the man who denies that Jesus is the Christ? He is the real Antichrist, the man who disowns the Father and the Son.

and no spiritual utterance which disowns Jesus can come from God; it is the utterance of Antichrist. You have heard that it is coming, and right now it is already in the world.

For many impostors have gone out into the world, men who do not own that Jesus Christ continues to come in human form. A person like this is the impostor and the Antichrist.
