Little children, it is the last hour; and as you have heard that the Antichrist is coming, even now many antichrists have come; by this we know that it is the last hour.

Who is the liar but he who denies that Jesus is the Christ? This is the Antichrist, he who denies the Father and the Son.

and every spirit which does not confess Jesus is not of God. This is the spirit of the Antichrist, of which you have heard that it was coming, and now it is in the world already.

For many deceivers, who do not acknowledge Jesus Christ as coming in the flesh, have gone out into the world. Any such person is the deceiver and the antichrist.
