Grace

“If you have it [love], you don't need to have anything else, and if you don't have it, it doesn't matter much what else you have.”
― J.M. Barrie

“Knowledge can last, principles can last, habits can last; but feelings come and go... But, of course, ceasing to be "in love" need not mean ceasing to love. Love in this second sense — love as distinct from "being in love" — is not merely a feeling. It is a deep unity, maintained by the will and deliberately strengthened by habit; reinforced by (in Christian marriage) the grace which both partners ask, and receive, from God... "Being in love" first moved them to promise fidelity: this quieter love enables them to keep the promise. It is on this love that the engine of marriage is run: being in love was the explosion that started it.”
― C.S. Lewis, Mere Christianity

“It will be your duty, and it will be your pleasure too—of course I know that; I am not delivering a lecture—to estimate her (as you chose her) by the qualities she has, and not by the qualities she may not have. The latter you must develop in her, if you can. And if you cannot, child,' here my aunt rubbed her nose, 'you must just accustom yourself to do without 'em. But remember, my dear, your future is between you two. No one can assist you; you are to work it out for yourselves. This is marriage, Trot; and Heaven bless you both, in it, for a pair of babes in the wood as you are!”
― Charles Dickens, David Copperfield

“What Is Love? I have met in the streets a very poor young man who was in love. His hat was old, his coat worn, the water passed through his shoes and the stars through his soul”
― Victor Hugo , Les Misérables
