2 John 7-11 New Life Version (NLV)
7 There are many false teachers in the world. They do not say that Jesus Christ came in a human body. Such a person does not tell the truth. He is the false-christ. 8 Watch yourselves! You do not want to lose what we have worked for. You want to get what has been promised to you.
9 Anyone who goes too far and does not live by the teachings of Christ does not have God. If you live by what Christ taught, you have both the Father and the Son. 10 If a person comes to you with some other kind of teaching, do not take him into your home. Do not even greet him. 11 The person who does has a share in his sins.
