And this is his commandment, That we should believe on the name of his Son Jesus Christ, and love one another, as he gave us commandment.
And he that keepeth his commandments dwelleth in him, and he in him. And hereby we know that he abideth in us, by the Spirit which he hath given us.

A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another.
By this shall all men know that ye are my disciples, if ye have love one to another.
These things I command you, that ye love one another.
