2 John 7-9 King James Version (KJV)
7 For many deceivers are entered into the world, who confess not that Jesus Christ is come in the flesh. This is a deceiver and an antichrist.
8 Look to yourselves, that we lose not those things which we have wrought, but that we receive a full reward.
9 Whosoever transgresseth, and abideth not in the doctrine of Christ, hath not God. He that abideth in the doctrine of Christ, he hath both the Father and the Son.
