2 John 1:4-6

4 I was greatly delighted to find some of your children walking in truth, just as we have been commanded by the Father.

5 Now I ask you, lady, not as if I were writing to you a new commandment, but [simply reminding you of] the one which we have had from the beginning, that we[2] love and unselfishly seek the best for one another.

6 And this is love: that we walk in accordance with His commandments and are guided continually by His precepts. This is the commandment, just as you have heard from the beginning, that you should [always] walk in love.
