The idea of a fear of God has fallen out of vogue. But anciently people understood that a fear of God, which really just means we have some understanding of, and are serious about what is going on here on earth, is a good thing. If we are going to understand the finner points of doctrine we must fear God. The unholy do not receive the holy, and not fearing God is unholy.
“The fear of the Lord is the beginning of wisdom: and the knowledge of the holy is understanding.” (Proverbs 9:10)
“..fear of God is faith.” (The Zohar, Matt vol. 2, pg 280, Teledot)
