Static and Kinetic Creation in "Good Omens"

The creation of worlds has been a central concern in our discussion of the fantasy genre. In Good Omens, Neil Gaiman and Terry Pratchett offer some particularly interesting perspectives on that topic. During Crowley and Aziraphale’s final discussion on the topic of ineffability Crowley makes a particularly memorable series of observations:
“Why do that if you really don’t want them to eat it, eh? I mean, maybe you just want to see how it all turns out. Maybe it’s all part of a great big ineffable plan. All of it. You, me, him, everything. Some great big test to see if what you’ve built works properly.”
With those observations, Crowley hints at another similar question. Why would one build a world if not to populate it and put it into motion. One could easily, upon considering that question, draw a comparison between the Judeo-Christian concept of God, and any random individual whose ever thought up a world of their own (which is probably all of us). What would be the purpose of creating such a world, if one did not set it into motion in order to see what happens, or could happen within. The questioning of the ineffable plan naturally comes to the distinction between static and kinetic creation. God can easily be seen as doing precisely what any imaginative mind bent on the telling of stories does, creating a world to explore and experiment with its possibilities.
Given both writers’ dispositions towards creating elaborate worlds of their own, this certainly seems probable that this comparison was a consideration for them when choosing to create a text which focused on Judeo-Christian belief and dogma, particularly given the nature of their collaboration. As both writers affected the text in a dichotomous way, and consequently neither could know for certain the course the events of the novel would take, there is an element of experimentation in the creation of this text which is far more pronounced than in any work of a lone creator in regards to creating and affecting a unique world.
