Let love be genuine. Abhor what is evil; hold fast to what is good.  Love one another with brotherly affection. Outdo one another in showing honor.
 Owe no one anything, except to love each other, for the one who loves another has fulfilled the law.  For the commandments, “You shall not commit adultery, You shall not murder, You shall not steal, You shall not covet,” and any other commandment, are summed up in this word: “You shall love your neighbor as yourself.”  Love does no wrong to a neighbor; therefore love is the fulfilling of the law. (ESV)
1 Corinthians 10:24
 Let no one seek his own good, but the good of his neighbor. (ESV)
1 Corinthians 13
 If I speak in the tongues of men and of angels, but have not love, I am a noisy gong or a clanging cymbal.  And if I have prophetic powers, and understand all mysteries and all knowledge, and if I have all faith, so as to remove mountains, but have not love, I am nothing.  If I give away all I have, and if I deliver up my body to be burned, but have not love, I gain nothing.
 Love is patient and kind; love does not envy or boast; it is not arrogant  or rude. It does not insist on its own way; it is not irritable or resentful;  it does not rejoice at wrongdoing, but rejoices with the truth.  Love bears all things, believes all things, hopes all things, endures all things.
 Love never ends. As for prophecies, they will pass away; as for tongues, they will cease; as for knowledge, it will pass away.  For we know in part and we prophesy in part,  but when the perfect comes, the partial will pass away.  When I was a child, I spoke like a child, I thought like a child, I reasoned like a child. When I became a man, I gave up childish ways.  For now we see in a mirror dimly, but then face to face. Now I know in part; then I shall know fully, even as I have been fully known.
 So now faith, hope, and love abide, these three; but the greatest of these is love. (ESV)
1 Corinthians 16:14
 Let all that you do be done in love. (ESV)
