I can be a pragmatic person sometimes, pushing limits, but knowing them nonetheless.
But how do you square pragmatic limit-knowing with an untamed God?
Knowing that God is out there, at work, creates a fog around the boundaries of the possible. You know what you can do, left to yourself. But you hope you won't be left to yourself.
This fog around the boundaries of the possible creates the possibility of failure. Risk.
But would you have it any other way?
