The Queen’s Guard, who stand watch at Buckingham Palace are famous for their silence. In fact, they’re often as famous for their stoic speechlessness as much as they are for their bright red and black uniforms, bearskin helmets and bayonet rifles. They don’t say anything, even if tourists approach them to say “hello,” or have their picture taken. They stand watch. When God made Ezekiel “a watchman for the house of Israel,” He made clear that his calling was to speak, and not to remain silent.
