President Harold B. Lee explained: “One is converted when he sees with his eyes what he ought to see; when he hears with his ears what he ought to hear; and when he understands with his heart what he ought to understand. And what he ought to see, hear, and understand is truth—eternal truth—and then practice it. That is conversion. But when he fails to see, and fails to hear, and fails to understand truth and apply it in his life for some reason, then that man has lost his faith. He has lost his testimony because of something he has done” (Stand Ye in Holy Places, 92).
