The devil’s propaganda says that, “stolen waters are sweet.” This is a way of saying that things that are forbidden are inviting. When a person takes something that doesn’t belong to them, especially if it is someone else’s spouse, they are acting up upon this deception. They are allured by the excitement of doing something wrong. The greater the wrong, the greater the sweetness says this outlook. The world might express it by saying they get a rush when they commit certain sins.
