2 John 7-11 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.
10 If there come any unto you, and bring not this doctrine, receive him not into your house, neither bid him God speed:
11 For he that biddeth him God speed is partaker of his evil deeds.
2 John 7-11 New Living Translation (NLT)
7 I say this because many deceivers have gone out into the world. They deny that Jesus Christ came[a] in a real body. Such a person is a deceiver and an antichrist. 8 Watch out that you do not lose what we[b] have worked so hard to achieve. Be diligent so that you receive your full reward. 9 Anyone who wanders away from this teaching has no relationship with God. But anyone who remains in the teaching of Christ has a relationship with both the Father and the Son.
10 If anyone comes to your meeting and does not teach the truth about Christ, don’t invite that person into your home or give any kind of encouragement. 11 Anyone who encourages such people becomes a partner in their evil work.
