2 John 1:4-6

1:4 I rejoiced greatly because I have found some of your children living according to the truth, just as the Father commanded us.

Warning Against False Teachers

1:5 But now I ask you, lady (not as if I were writing a new commandment to you, but the one we have had from the beginning), that we love one another. 1:6 (Now this is love: that we walk according to his commandments.) This is the commandment, just as you have heard from the beginning; thus you should walk in it.
