Because GW wasn't "perfect"

  Nor was "modern life" exactly like the Bible on its surface.  

  And, situations come up that don't automatically fit in a framework of simple Christianity. 

  Jesus praying in the garden before his death is a similar idea to think about. 

  In the winter of Valley Forge, George Washington was feeling like the idea of the nation was under the weight of harsh reality.  "It" seemed to be coming apart, in crisis, maybe even not what was supposed to be. 

  Jesus was understanding he'd been sold out, his ideas of love and forgiveness (that his Father had created him to teach as the better way) coming up against violence and eradication.  He knew at that time, his time on earth was coming to an end. 

  There's a thread of submission to Higher Power.  Allowing the Judeo-Christian God to lead the leader.  At least admitting, need a little help here, "I'm not God"; there's what seems to be and there is God's awesomeness (not always feel-good or instant).  

  The act of prayer. 

  Can happen for a lot of reasons--from gratitude to pleading, for strength to guidance, even "chastisement" or help me get this thing back on track, better in line with your will. 

  Prayer is an act of reflection and bonding even in the midst of "live action".  It connects people to the Creator and can be spiritual AND concrete.  It doesn't always look like hands folded and head bowed though those gestures have come to symbolize the notion of "talking with". 

  Intricacies arise when we consider "prayer" and the world being made up of many cultures.  

  For instance, bowing head to God, and, combining human action with religiosity.  

  Human interpretation of "God's will" can be very personalized, but it can also be ritualized and shared.  This gets into ideology.  And the mix of religion with other ideas about life can make for complex ideology. 

  I think, in many ways, it's not only the Judeo-Christian worldview that is often stripped down by "believers" to literally Biblical, based on, and... claims of because God made it so.

  And, there are many diverse groups using generic notions of "faith" and "power" to couple with existing traditions and fragments of more powerful. 

  Theocratic arguments.    

  Philosophical arguments.

  Political arguments. 

  Then in the Twentieth Century and beyond, so far, weaponry and technology in abundance.  More so than food and function.
