To love is to respect the other, to seek his or her happiness, to cultivate empathy for his or her feelings, to dispose oneself in the knowledge of a body, a psychology, and a soul that are not our own, and that must be contemplated for the beauty they bear. That is love, and love is beautiful. Lust, on the other hand, makes a mockery of all this: lust plunders, it robs, it consumes in haste, it does not want to listen to the other but only to its own need and pleasure; lust judges every courtship a bore, it does not seek that synthesis between reason, drive and feeling that would help us to conduct existence wisely. The lustful seeks only shortcuts: he does not understand that the road to love must be travelled slowly, and this patience, far from being synonymous with boredom, allows us to make our loving relationships happy. https://opusdei.org/en-us/article/lust-seeks-only-shortcuts/
