Little children, it is the last hour: and as you have heard that antichrist is coming, even now many antichrists have come, from which we know that it is the last hour.

In this you know the Spirit of God: every spirit which confesses that Jesus Christ has come in the flesh is of God:

He is the one having come through water and blood, Jesus Christ; not by water only, but by water and blood; the Spirit is the one who bears witness, because the Spirit is the truth.

But we know that the Son of God has come and has given unto us intelligence, that we know the truth. And we are in the true one, in his Son Jesus Christ; he is the true God, and eternal life.
