1 Corinthians 13 (ESV)
Mark of true greatness is walking in the way of love
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. 2 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. 3 If I give away all I have, and if I deliver up my body to be burned, but have not love, I gain nothing.
4 Love is patient and kind;
love does not envy or boast;
it is not arrogant5 or rude.
It does not insist on its own way;
it is not irritable or resentful;
6 it does not rejoice at wrongdoing, but rejoices with the truth.
7 Love bears all things, believes all things, hopes all things, endures all things.
8 Love never ends.
As for prophecies, they will pass away; as for tongues, they will cease; as for knowledge, it will pass away. 9 For we know in part and we prophesy in part, 10 but when the perfect comes, the partial will pass away. 11 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. 12 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.
13 So now faith, hope, and love abide, these three; but the greatest of these is love.
Without true love you are a zero, even if you act and perform like a hero!"
