Peter Drucker was arguably one of the greatest management and leadership sages of the 20^th Century.  His wit and wisdom live on in many memorable quotes like:  “culture eats strategy for breakfast”; “if you can’t measure it, you can’t manage it”; and “efficiency is doing things right; effectiveness is doing the right things”.  What many people don’t know about Drucker is that he was a devout Christian.  Drucker communicated “stained glass” truth in “plain glass” language, making Biblical principles accessible to believers and non-believers alike.  Drucker discipled some of the giants of his era, like Bob Buford who founded Half Time; and the team that launched the Exponential church multiplication movement.  Let Drucker’s example inspire you to translate the “stained glass” truths you see at work into the “plain glass” truths your colleagues can readily grasp and apply.
