2 John 1:6; 2 John 1:7

2 John 1:6

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.

2 John 1:7

7 I say this because 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.
