„God asks questions in large part for the same reason humans ask questions: the desire for relationship. Commands and declarations create monologues, but only questions can create dialogues. Think of young children who ask the same questions over and over; these budding dialogues are attempts to bond with their parents. Parents listen and respond because they love their children. Conversely, think of political protestors, shouting their slogans; these are monologues.”
