This quote means that loving another person isn’t just a single act of kindness or affection, but is instead something that should be a part of your whole life. It implies that if you truly love someone, you should strive to show love and kindness to them every day; it is not something you only do once in a while. In other words, it is not enough just to tell someone you love them; you need to continually back up that statement with loving actions.
