⁷ I say this because many deceivers have gone out into the world. They deny that Jesus Christ came^[a] in a real body. Such a person is a deceiver and an antichrist.

Discerning False Prophets

4 Dear friends, do not believe everyone who claims to speak by the Spirit. You must test them to see if the spirit they have comes from God. For there are many false prophets in the world. ² This is how we know if they have the Spirit of God: If a person claiming to be a prophet^[a] acknowledges that Jesus Christ came in a real body, that person has the Spirit of God. ³ But if someone claims to be a prophet and does not acknowledge the truth about Jesus, that person is not from God. Such a person has the spirit of the Antichrist, which you heard is coming into the world and indeed is already here.

²⁶ I am writing these things to warn you about those who want to lead you astray.

Warning about Antichrists

¹⁸ Dear children, the last hour is here. You have heard that the Antichrist is coming, and already many such antichrists have appeared. From this we know that the last hour has come. ¹⁹ These people left our churches, but they never really belonged with us; otherwise they would have stayed with us. When they left, it proved that they did not belong with us.

²⁰ But you are not like that, for the Holy One has given you his Spirit,^[a] and all of you know the truth. ²¹ So I am writing to you not because you don’t know the truth but because you know the difference between truth and lies. ²² And who is a liar? Anyone who says that Jesus is not the Christ.^[b] Anyone who denies the Father and the Son is an antichrist.^[c]

The Danger of False Teachers

2 But there were also false prophets in Israel, just as there will be false teachers among you. They will cleverly teach destructive heresies and even deny the Master who bought them. In this way, they will bring sudden destruction on themselves. ² Many will follow their evil teaching and shameful immorality. And because of these teachers, the way of truth will be slandered. ³ In their greed they will make up clever lies to get hold of your money. But God condemned them long ago, and their destruction will not be delayed.
