2 John 1:5-8

And now, dear lady, this is not a new command but is the same command we have had from the beginning. I ask you that we all love each other. And love means living the way God commanded us to live. As you have heard from the beginning, his command is this: Live a life of love. Many false teachers are in the world now who do not confess that Jesus Christ came to earth as a human. Anyone who does not confess this is a false teacher and an enemy of Christ. Be careful yourselves that you do not lose everything you have worked for, but that you receive your full reward.
