7 For many deceivers have gone out into the world, those who don't confess that Jesus Christ came in the flesh. This is the deceiver and the Antichrist.
But there also arose false prophets among the people, as among you also there will be false teachers, who will secretly bring in destructive heresies, denying even the Master who bought them, bringing on themselves swift destruction. Many will follow their immoral{TR reads "destructive" instead of "immoral"} ways, and as a result, the way of the truth will be maligned. In covetousness they will exploit you with deceptive words: whose sentence now from of old doesn't linger, and their destruction will not slumber.
Little children, these are the end times, and as you heard that the Antichrist is coming, even now many antichrists have arisen. By this we know that it is the end times. They went out from us, but they didn't belong to us; for if they had belonged to us, they would have continued with us. But they left, that they might be revealed that none of them belong to us. You have an anointing from the Holy One, and you know the truth. I have not written to you because you don't know the truth, but because you know it, and because no lie is of the truth. 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.
Beloved, don't believe every spirit, but test the spirits, whether they are of God, because many false prophets have gone out into the world. By this you know the Spirit of God: every spirit who confesses that Jesus Christ has come in the flesh is of God, and every spirit who doesn't confess that Jesus Christ has come in the flesh is not of God, and this is the spirit of the antichrist, of whom you have heard that it comes. Now it is in the world already.
