the bible on love

Let love be without hypocrisy. Abhor what is evil. Cling to what is good. Be kindly affectionate to one another with brotherly love, in honor giving preference to one another; not lagging in diligence, fervent in spirit, serving the Lord; rejoicing in hope, patient in tribulation, continuing steadfastly in prayer; distributing to the needs of the saints, given to hospitality.
Bless those who persecute you; bless and do not curse. Rejoice with those who rejoice, and weep with those who weep. Be of the same mind toward one another. Do not set your mind on high things, but associate with the humble. Do not be wise in your own opinion.
Repay no one evil for evil. Have regard for good things in the sight of all men. If it is possible, as much as depends on you, live peaceably with all men. Beloved, do not avenge yourselves, but rather give place to wrath; for it is written, “Vengeance is Mine, I will repay,” says the Lord. Therefore
      “ If your enemy is hungry, feed him;
        If he is thirsty, give him a drink;
        For in so doing you will heap coals of fire on his head.”   
Do not be overcome by evil, but overcome evil with good.
Romans 12:9-21

Love prospers when a fault is forgiven, but dwelling on it separates close friends
Proverbs 17:9

If I speak in the tongues of men and angels, but have not love, I am only a resounding gong or clanging symbol. If I have the gift of prophesy and can fathom all mysteries and all knowledge, and if I have a faith that can move mountains, but have not love, I am nothing. If I give all my possessions to the poor and surrender my body to the flames, but have not love, I gain nothing.
1 Corinthians 13:1-3

Above all, love each other deeply, because love covers over a multitude of sins.

1 Peter 4:8
