John 13:34

"A new command I give you: Love one another. As I have loved you, so you must love one another."

A new command
John 15:12 "My command is this: Love each other as I have loved you."
1 John 2:7-11 Dear friends, I am not writing you a new command but an old one, which you have had since the beginning. This old command is the message you have heard. Yet I am writing you a new command; its truth is seen in him and you, because the darkness is passing the the true light is already shining. Anyone who claims to be in the light but hates his brother is still in the darkness. Whoever loves his brother lives in the light, and there is nothing in him to make him stumble. But whoever hates his brother is in darkness and walks around in the darkness; he does not know where he is going, because the darkness has blinded him.
1 John 3:11 This is the message you heard from the beginning: We should love one another.

Love one another
Leviticus 19:18 "'Do not seek revenge or bear a grudge against one of your people, but love your neighbor as yourself. I am the LORD.'"
1 Thessalonians 4:9 Now about brotherly love we do not need to write to you, for you yourselves have been taught by God to love each other.
1 Peter 1:22 Now that you have purified yourselves by obeying the truth so that you have sincere love for your brothers, love one another deeply, from the heart.

so you must love one another
Ephesians 5:2 ... and live a life of love, just as Christ loved us and gave himself up for us as a fragrant offering and sacrifice to God.
1 John 4:10-11 This is love: not that we loved God, but that he loved us and sent his Son as an atoning sacrifice for our sins. Dear friends, since God so loved us, we also ought to love one another.
