"In good men, the fear of God is a holy awe or reverence of God and his laws, which springs from a just view and real love of the divine character, leading the subjects of it to hate and shun every thing that can offend such a holy being, and inclining them to aim at perfect obedience. This is filial fear."NKJV Dictionary
Let us hear the conclusion of the whole matter:
Fear God, and keep his commandments:
for this is the whole duty of man.
Ecclesiastes 12:13
