You always have to watch out when someone steeples their fingers. (George W. Bush, 43rd U.S. president)
We may not know for sure what Bush was referring to. Was he thinking of someone whose posture suggested deep and intense thought? Or was he referring to the posture of prayer? In either case, you want to pay careful attention to such people. Deep thinkers can offer good counsel, and people who sincerely pray will always be an asset and encouragement.
The earnest prayer of a righteous person has great power and produces wonderful results. (James 5:16)
