II John 1

7Many deceivers, who do not acknowledge Jesus Christ as coming in the

flesh, have gone out into the world. Any such person is the deceiver and the

antichrist. 8Watch out that you do not lose what you have worked for, but

that you may be rewarded fully. 9Anyone who runs ahead and does not continue

in the teaching of Christ does not have God; whoever continues in the

teaching has both the Father and the Son. 10If anyone comes to you and does

not bring this teaching, do not take him into your house or welcome him.

11Anyone who welcomes him shares in his wicked work.
