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 So I want you to know that no one speaking by the Spirit of God will curse Jesus, and no one can say Jesus is Lord, except by the Holy Spirit.

¹⁴ So the Word became human^[a] and made his home among us. He was full of unfailing love and faithfulness.^[b] And we have seen his glory, the glory of the Father’s one and only Son.

¹⁶ Without question, this is the great mystery of our faith^[a]:

Faith in the Son of God

5 Everyone who believes that Jesus is the Christ^[a] has become a child of God. And everyone who loves the Father loves his children, too.

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.

¹³ When the Spirit of truth comes, he will guide you into all truth. He will not speak on his own but will tell you what he has heard. He will tell you about the future. ¹⁴ He will bring me glory by telling you whatever he receives from me. ¹⁵ All that belongs to the Father is mine; this is why I said, ‘The Spirit will tell you whatever he receives from me.’

²³ Anyone who denies the Son doesn’t have the Father, either. But anyone who acknowledges the Son has the Father also.
