'Anti christ' in the Bible

Children, it is the last hour. And as you have heard, “Antichrist is coming,” even now many antichrists have come. We know from this that it is the last hour.

Who is the liar, if not the one who denies that Jesus is the Messiah? This one is the antichrist: the one who denies the Father and the Son.

But every spirit who does not confess Jesus is not from God. This is the spirit of the antichrist; you have heard that he is coming, and he is already in the world now.

Many deceivers have gone out into the world; they do not confess the coming of Jesus Christ in the flesh. This is the deceiver and the antichrist.
