'Love One Another' in the Bible

For this is the message that ye heard from the beginning, that we should love one another.

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.

Beloved, let us love one another: for love is of God; and every one that loveth is born of God, and knoweth God.

Beloved, if God so loved us, we ought also to love one another.

No man hath seen God at any time. If we love one another, God dwelleth in us, and his love is perfected in us.
