2 John 1:4-6

4I was overjoyed to find some of your children walking in truth, just as we received as a commandment from the Father.

5Now I ask you, dear lady, that we love one another. It is not as though I am writing you a new command, but the one we have had from the beginning.

6Now this is love: that we walk according to His commands. This is the commandment—just as you heard from the beginning—that you walk in love.
