5 And now, dear lady, I tell you: We should all love each other. This is not a new command. It is the same command we have had from the beginning.
6 And loving means living the way he commanded us to live. And God’s command is this: that you live a life of love. You have heard this command from the beginning.
7 Many false teachers are in the world now. They refuse to say that Jesus Christ came to earth and became a man. Anyone who refuses to say this is a false teacher and an enemy of Christ.
8 Be careful! Do not lose the reward that you have worked for. Be careful, so that you will receive your full reward.
9 A person must continue to follow only the teaching of Christ. If he goes beyond Christ’s teaching, then he does not have God. But if he continues following the teaching of Christ, then he has both the Father and the Son.
10 If someone comes to you, but does not bring this teaching, then do not accept him into your house. Do not welcome him.
11 If you accept him, you are helping him with his evil work.
