 Hereby know ye the Spirit of YHVH Almighty God: "Every spirit that confessed that Jesus Christ is come in the flesh is of God"

And every spirit that confessed not that Jesus Christ is come in the flesh is not of YHVH Almighty God: and this is that spirit of Antichrist, whereof ye have heard that it should come; and even now already is it in the world.

1 John 4:2-3
