Thematic Bible: What love is

Owe no one anything, but love one unto another; for he that loves his neighbour has fulfilled the law. For this, Thou shalt not commit adultery, Thou shalt not murder, Thou shalt not steal, Thou shalt not bear false witness, Thou shalt not covet, and if there is any other commandment, it is briefly comprehended in this saying, namely, Thou shalt love thy neighbour as thyself. Charity works no evil to a neighbour; therefore, charity is the fulfillment of the law.

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 charity. I have rejoiced greatly, for I have found of thy sons that they walk in the truth, as we have received the 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. read more.
And this is charity, that we walk after his commandment. And this is the commandment, That ye walk in him, as ye have heard from the beginning.
