1 John 4:2-4

New Living Translation

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.

⁴ But you belong to God, my dear children. You have already won a victory over those people, because the Spirit who lives in you is greater than the spirit who lives in the world.
