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.
