People often speak of the fear of the Lord and, thereby, mean different things.  “Fearing” God is a large concept embracing many aspects of faith.  One of these aspects is mentioned in Proverbs 8:13

To fear the Lord is to hate evil.

Indeed, the latter is a pretty good index of the former: how much you hate evil probably tells one how much you fear God.

To hate evil is not merely to hate evil that you see around you—that is all too easily achieved.  Genuine hatred of evil most of all begins with hatred of evil within yourself.  Is your hatred of evil genuine?
