'Love One Another' in the Bible

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

For this is his commandment, that we should believe on the name of his Son, Jesus Christ, and should love one another as he gave us commandment.

Beloved, let us love one another; for love is from God: and every one who loves, has been begotten by God, and knows God.

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

No one has seen God, at any time. If we love one another, God abides in us, and his love is made perfect in us.
