4 It has given me great joy to find some of your children walking in the truth, just as the Father commanded us. 5 And now, dear lady, I am not writing you a new command but one we have had from the beginning. I ask that we love one another. 6 And this is love: that we walk in obedience to his commands. As you have heard from the beginning, his command is that you walk in love. 7 Many 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. 8 Watch out that you do not lose what you have worked for, but that you may be rewarded fully. 9 Anyone 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. 10 If anyone comes to you and does not bring this teaching, do not take him into your house or welcome him. 11 Anyone who welcomes him shares in his wicked work.
