Paul begins with three statements. Though he speaks in the tongues of men and of angels, if he has not love, he is a noisy gong or a clanging cymbal. Though he has prophetic powers, understands all mysteries and all knowledge, and has all faith to move mountains, if he has not love, he is nothing. And though he gives away all he has to the poor and surrenders his body to be burned, if he has not love, he gains nothing.
He then describes love with a series of traits. Love is patient and kind. It 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. It bears all things, believes all things, hopes all things, endures all things.
Love never ends, whereas prophecies will pass away, tongues will cease and knowledge will pass away. For now we know in part and prophesy in part, but when the perfect comes, the partial will pass away. Paul compares this to childhood: when he was a child he spoke, thought and reasoned like a child, but when he became a man he put childish ways behind him. For now we see in a mirror dimly, but then face to face; now I know in part, but then I shall know fully, even as I have been fully known.
The chapter ends by saying that now faith, hope and love abide, and the greatest of these is love.
