2 John 1:5 And now I beseech thee, lady, not as though I wrote a new commandment unto thee, but that which we had from the beginning, that we love one another.
6 And this is love, that we walk after his commandments. This is the commandment, That, as ye have heard from the beginning, ye should walk in it.
John starts in theses verses to remind us of the commandment to love one one anther. In first John , he talked a lot about love and how important it is not only to love one another but ot love God first. If we can not love one anther we cannot love God. He also reminds us to walk daily in these commandments that we have heard from the beginning. I believe John emphasis on love is very important or he would not continue to bring it up. If we strive to walk in this commandment every day we will be less likely to not do the will of God that He has in store for us each day..
