" The things you are certain of at age twenty-five lose a lot of luster by age forty, and even more by age fifty. As you follow God and hear from him and watch him work—and also watch him choose not to speak and act—the greater the chances that your early conception of him will be hidden in shadow. Over time, as you continue to follow God, you gain a humbler attitude about what you say about God. You also gain a desire for clarity and simplicity when you speak about God. "
