"[..] The letter kills, but the Spirit gives life."

BibleGateway.com - Passage Lookup: 2 Corinthians 3:6

6He has made us competent as ministers of a new covenant—not of the letter but of the Spirit; for the letter kills, but the Spirit gives life.

Not a passage that I think I've ever heard cited or preached upon, in all my nearly 35 years.  I'll be thinking about this one for a while.
