While I agree with your sentiment, I totally feared my Dad when my Mom said I was going to get a spanking when Dad got home, and he was the most loving and kind father you could have. It's healthy to fear things like gravity and explosives and such, it makes you act wisely. This doesn't mean you're shaking in your boots in fear, but that you know what could be done in undesirable circumstances. If we fear anyone, it should be the omnipotent, all-knowing God.
