Q: You use the biblical story of David and Goliath in the title and the setup to your book. Do you think we’ve been retelling the story poorly?
A: I think there has been an overemphasis of the idea that David’s victory was improbable. When you look closer to that story and you understand the full historical context, you see it from a different perspective. Here was a guy who brilliantly changed the rules of combat. He was equipped with a sling that was routinely used by armies to defeat the sort that Goliath was. David was very skilled at using the weapon and he was filled with the spirit of the Lord. Put those things together, why is he an underdog? He’s smarter than his opponent, better armed and he had this extraordinary force in his heart. When you understand that perspective, you understand that sometimes our instinct about where power comes from is wrong.
