@Jasper10,
How about the biggest Set that can ever be. Lets call it from our POV the potential Set.
The sum not only of what is but what was and what will happen.
This Set has a rational/order but is not alive because it needs not being alive, it encompasses everything therefore it doesn't move anywhere. It is on itself timeless.
Now tell me how does your God is bigger than the sum of "creation" and "creator", or bigger then the sum of all that can be? It is a simple math question and you should be able to answer it.
PS - By the way I posed this question to my Catholic catechist when I was around 12 years old.
