Measuring Spirituality

How does one measure spirituality? Years ago I would've said "knowledge of the Bible". The people I looked up to could quote Scripture left and right. The were Bible junkies...people who'd beat your pants off playing Bible Trivia Pursuit.

As I got older I became a little more discerning. I noticed something disturbing: many of the Bible know-it-alls treated others poorly. They had little compassion...a terrible temper...were extremely judgmental or critical...etc. I would now argue that there's very little correlation between knowledge of the Bible and Spiritual maturity.

What I'm saying is this--it's not how much of the Bible you know that makes you mature--it's how much of the Bible you live out.
