2 John 1:7-11

7 Because a number of false teachers have gone out into the world, who do not give witness that Jesus Christ came in the flesh. Such a one is a false teacher and Antichrist.

8 Keep watch over yourselves, so that you do not make our work of no effect, but may get your full reward.

9 Anyone who goes on and does not keep to the teaching of Christ, has not God: he who keeps to the teaching has the Father and the Son.

10 If anyone comes to you not having this teaching, do not take him into your house or give him words of love:

11 For he who gives him words of love has a part in his evil works.
