"I tell you, not even in Israel have I found such faith." Jesus said this massively affirming thing about a Gentile; a Centurion soldier who believed Jesus could heal his servant from afar by just commanding it. This Centurion knows and understands authority; he is under the authority of others and commands authority over his soldiers. Likewise, he believes something about Jesus that few others understood. He believes Jesus, the object of his faith, has the authority to command anything in heaven and earth.
