John 13:34

1 Corinthians 12:26-27 NIV
If one part suffers, every part suffers with it; if one part is honored, every part rejoices with it. Now you are the body of Christ, and each one of you is a part of it.

1 John 2:7-10 NIV
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 in you, because the darkness is passing and the true light is already shining. Anyone who claims to be in the light but hates a brother or sister is still in the darkness. Anyone who loves their brother and sister lives in the light, and there is nothing in them to make them stumble.

1 John 3:11 NIV
For this is the message you heard from the beginning: We should love one another.

1 John 3:14-18 NIV
We know that we have passed from death to life, because we love each other. Anyone who does not love remains in death. Anyone who hates a brother or sister is a murderer, and you know that no murderer has eternal life residing in him. This is how we know what love is: Jesus Christ laid down his life for us. And we ought to lay down our lives for our brothers and sisters. If anyone has material possessions and sees a brother or sister in need but has no pity on them, how can the love of God be in that person? Dear children, let us not love with words or speech but with actions and in truth.

1 John 3:23 NIV
And this is his command: to believe in the name of his Son, Jesus Christ, and to love one another as he commanded us.

1 John 4:7-11 NIV
Dear friends, let us love one another, for love comes from God. Everyone who loves has been born of God and knows God. Whoever does not love does not know God, because God is love. This is how God showed his love among us: He sent his one and only Son into the world that we might live through him. 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.

1 Peter 1:22 NIV
Now that you have purified yourselves by obeying the truth so that you have sincere love for each other, love one another deeply, from the heart.

1 Thessalonians 3:12 NIV
May the Lord make your love increase and overflow for each other and for everyone else, just as ours does for you.

2 John 1:5 NIV
And now, dear lady, I am not writing you a new command but one we have had from the beginning. I ask that we love one another.

Colossians 3:12-13 NIV
Therefore, as God’s chosen people, holy and dearly loved, clothe yourselves with compassion, kindness, humility, gentleness and patience. Bear with each other and forgive one another if any of you has a grievance against someone. Forgive as the Lord forgave you.
