2 John 1:1-6
The elder unto the elect lady and her children, whom I love in truth; and not I only, but also all they that know the truth; for the truth’s sake which abideth in us, and it shall be with us for ever: Grace, mercy, peace shall be with us, from God the Father, and from Jesus Christ, the Son of the Father, in truth and love.
I rejoice greatly that I have found certain of thy children walking in truth, even as we received commandment from the Father.
And now I beseech thee, lady, not as though I wrote to thee a new commandment, but that which we had from the beginning, that we love one another.
And this is love, that we should walk after his commandments. This is the commandment, even as ye heard from the beginning, that ye should walk in it.
