Try relating to a robot, or even an animal, compared to a living human. There is a difference.
The difference shows relation to God is ultimately, the definition of life.
If I could understand this, I'd probably think it was self-serving hogwash. If God made us self-willed and self-directed on purpose, why do you think one of our most important purposes wouldn't be to develop moral restraints through observation, reason and education? God wanted us to find water and food for ourselves, didn't he? If God is such a big fan of free will, why do you think God invented our moral restraints free of charge when he couldn't bring himself to provide us with food and water free of charge?
