1 John 4:2-3
2
Hereby know ye the Spirit of God: every spirit that confesseth that Jesus Christ is come in the flesh is of God:
3
and every spirit that confesseth not Jesus is not of God: and this is the spirit of the antichrist, whereof ye have heard that it cometh; and now it is in the world already.
