Beware of Deceivers

7 For many deceivers have gone out into the world, refusing to confess the coming of Jesus Christ in [the] flesh. Any such [ person ] is the deceiver and the antichrist. 8 Watch yourselves, so that you do not lose what we have worked for,[fn] but [that] you may be fully rewarded. 9 Anyone who runs ahead without remaining in the teaching of Christ does not have God. Whoever remains in [His] teaching has both the Father and the Son.

10 If anyone comes to you [but] does not bring this teaching, {do} not receive him into [your] home [or] even greet him. 11 Whoever greets [such a person] shares in his evil deeds.
