2 John 1:5-7

5 And now I ask you, lady, not as though I wrote a new commandment to you, but that which we have had from the beginning, that we love one another.

6 And this is love: that we walk according to His commandments. This is the commandment, that as you have heard from the beginning, you should walk in it.

7 For many deceivers, who do not confess that Jesus Christ has come in the flesh, have gone out into the world. Each one is a deceiver and an antichrist.
