We are in total agreement about Monty Python. :) As for artists without purpose, I'm not sold. Their want/need to express is their purpose (as is, I think, their want to connect with others). Just because their purpose does not necessarily have a practical value, doesn't mean the purpose is absent. God as artist could just be some dude creating his own captive audience, and worship or "love" may be his/her/its only purpose.

I guess my point here is that God's purpose doesn't matter at a basic level. It doesn't change that an individual's fundamental purpose and value is him- or herself.
