Warnings Against Denying the Son

¹⁸ Dear children, this is the last hour;^(A) and as you have heard that the antichrist is coming,^(B) even now many antichrists have come.^(C) This is how we know it is the last hour. ¹⁹ They went out from us,^(D) but they did not really belong to us. For if they had belonged to us, they would have remained with us; but their going showed that none of them belonged to us.^(E)

²⁰ But you have an anointing^(F) from the Holy One,^(G) and all of you know the truth.^{[a](H) 21} I do not write to you because you do not know the truth, but because you do know it^(I) and because no lie comes from the truth. ²² Who is the liar? It is whoever denies that Jesus is the Christ. Such a person is the antichrist—denying the Father and the Son.^{(J) 23} No one who denies the Son has the Father; whoever acknowledges the Son has the Father also.^(K)

²⁴ As for you, see that what you have heard from the beginning^(L) remains in you. If it does, you also will remain in the Son and in the Father.^(M)

On Denying the Incarnation

4 Dear friends,^(A) do not believe every spirit,^(B) but test the spirits to see whether they are from God, because many false prophets have gone out into the world.^{(C) 2} This is how you can recognize the Spirit of God: Every spirit that acknowledges that Jesus Christ has come in the flesh^(D) is from God,^{(E) 3} but every spirit that does not acknowledge Jesus is not from God. This is the spirit of the antichrist,^(F) which you have heard is coming and even now is already in the world.^(G)

⁷ I say this because many deceivers, who do not acknowledge Jesus Christ^(A) as coming in the flesh,^(B) have gone out into the world.^(C) Any such person is the deceiver and the antichrist.^(D)
