QUOTE : Great spiritual teachers learn to balance knowing with not knowing, as illustrated in this oft-quoted aphorism: "It ain't what you don't know that gets you into trouble. It's what you know for sure that just ain't so." The true biblical notion of faith, which balances knowing with not knowing, is rather rare today, especially among many religious folks who think faith is being certain all the time--when the truth is the exact opposite. But we have little theology of darkness today.
