Boundry Lines

I remember as a kid how important it was before starting a game that everyone knew where the lines were. If it was baseball you had to make sure that everyone knew that if you hit the ball over the fence along the first base/right field area it was a foul ball, but if the ball landed in the irrigation ditch you were automatically out. Then if you were playing basketball the question would be did you step out of bounds and thus turn the ball over or were you just close. Interpreting the boundaries were sometimes clear and other times not, but in almost every game you could count on their being some energy and time spent on arguing over who could call the boundaries in or out.
At the age of 47 now I'm wondering what boundaries are really worth arguing about. Is it possible that the boundaries we set in our lives are not always the best or most logical place to draw the lines? Is it possible that we might find God present in the "out of bounds area" even more than within the set boundaries? I don't know but it doesn't help when I read books like this one by Steve Taylor.

edit: As I'm reading this again it strikes me that I had better clarify just a bit. Yes there are very clear boundaries in life when it comes to relationships, etc.
What I'm thinking over and pondering are the spiritual / church boundaries that we establish of where and how the Holy can be encountered. Do we make artificial boundaries in life and expect God to only show up within those "safe" areas? Would Moses ever have expected God to show up in a burning bush? Maybe the bush had been burning for a long time and no one else had seen it because it was outside of their religious boundaries and so they weren't able to see the living God there.
I don't know, just some random thoughts that have been floating around my head for the last couple of days.
