2 John 1:3-5

Grace be with you, mercy, and peace, from God the Father, and from the Lord Jesus Christ, the Son of the Father, in truth and love. I rejoiced greatly that I found of thy children walking in truth, as we have received a commandment from the Father. 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.
