1 John 4:2-3

Hereby know ye the Spirit of JAH: every spirit that confesses that Yesu Kristo is come in the Flesh is of JAH. And every spirit that confesses not that Yesu Kristo is come in the Flesh is not of JAH and this is that spirit of anti-Kristo, whereas, ye have heard that it should come; and even now already is it in the world.
