 That word literally has the meaning of empty or shallowness. You know, so many that are living in our world and seem to have all the things the world says are important, wealth, position, fame, and on and on it goes, they're living in vanity. It's empty. Have you noticed that those people can never get enough money? They can never have a big enough house. They can never have enough followers on social media or enough people giving them attention.
