The fear of God is the beginning of wisdom; till you see Him to be a consuming fire, and approach Him with reverence and godly fear, as being sinners, you are not even in sight of the strait gate.
--Blessed John Henry Newman, "The Religion of the Day", Parochial and Plain Sermons
Not only are we missing something when fear is absent from religion, but (far worse) we are sinning grievously. For the absence of the fear of God is arrogance and pride. How dare sinners sashay up to God as a chum without first falling down in repentance and fear and calling on the Blood of Christ to save us?
