Here are the opening lines of the book Jesus' Plan for a New World: The Sermon on the Mount by Richard Rohr...
We know everything todayAnd believe almost nothing.
It is not reason that drives our lives, But passion or the search for it. It is not words and concepts, But living images that grab our souls. It is not what we know that haunts us at the end, But what we did not know and don't know yet.
We much make friends with the unknowing, What you know is just ten thousand different things.
But what you believeIs what you pay attention to, What you care about, What finally lives and matters in you.
What you believe is not one of ten thousand things, It is that which sees ten thousand things.
It is not what you know that matters, Or changes anything: It is what you believe -
And believe all the way through.
