'Anti christ' in the Bible

Little children, it is the last hour, and, according as ye have heard that antichrist comes, even now there have come many antichrists, whence we know that it is the last hour.

Who is the liar but he who denies that Jesus is the Christ? He is the antichrist who denies the Father and the Son.

and every spirit which does not confess Jesus Christ come in flesh is not of God: and this is that power of the antichrist, of which ye have heard that it comes, and now it is already in the world.

For many deceivers have gone out into the world, they who do not confess Jesus Christ coming in flesh this is the deceiver and the antichrist.
