Proverbs 16:6 tells us that by the fear of the Lord, one departs from evil. Proverbs 8:13 sheds more light on this: " The fear of the LORD is to hate evil;"
Some sincere Christians have lists of man-made rules that they follow. They believe these lists are necessary, because they won't know how to live holy lives without them. Furthermore, they believe that obeying these lists will keep them out of situations that will bring them into sin. Yet, these groups have as many scandals in their leadership as other groups. One such group, the Ruckmanites, have more scandals than most other Christian groups.
The fear of the Lord does for Christians what man-made rules fail to do. The lists don't make you hate evil (many people under the authority of those lists don't want to obey them, but their church makes them). The fear of the Lord, on the other hand, makes you hate evil and makes you depart from it.
