2 John 1:4-6

4 I rejoiced greatly that I have found some of your children walking in truth, as we received commandment from the Father.

5 And now I plead with 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 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.
