Just my two cents.
Fortunately for us, the Bible defines the fear of the Lord at least twice (that I know of).
Proverbs 1:7 – “The fear of the Lord is the beginning of wisdom.” Why is fearing God going to start us on a path of wise living? Because of Proverbs 8:13.
Proverbs 8:13 – “To fear the Lord is to hate evil – pride, and arrogancy, and the evil way, and the perverse mouth.”
When I think of fearing the Lord in this context, I have to use Shiphrah and Puah as an example of people who hated evil so much and had reverence for God and His ways so much that they put their own life in peril to not commit evil acts that they were commanded to do.
They refused to kill the baby boys of the Israelite slaves of Egypt. The Bible says this about them.
"The king of Egypt said to the Hebrew midwives, whose names were Shiphrah and Puah, “When you are helping the Hebrew women during childbirth on the delivery stool, if you see that the baby is a boy, kill him; but if it is a girl, let her live.” The midwives, however, feared God and did not do what the king of Egypt had told them to do; they let the boys live. Then the king of Egypt summoned the midwives and asked them, “Why have you done this? Why have you let the boys live?” The midwives answered Pharaoh, “Hebrew women are not like Egyptian women; they are vigorous and give birth before the midwives arrive.” So God was kind to the midwives and the people increased and became even more numerous. And because the midwives feared God, he gave them families of their own." Exodus 1:17-21
Fearing the Lord – hating evil and submitting to His wisdom and living a life of obedience to Him does not come from being afraid of Him. We are told many times in the Bible to NOT be afraid.
And how can we be afraid of the One who loves us more that we could ever know and sent His Son to die for us and shows us mercy, grace, and patience that we do not deserve.
"For I am convinced that neither death nor life, neither angels nor demons, neither the present nor the future, nor any powers, neither height nor depth, or anything else in creation, will be able to separate us from the love of God that is in Christ Jesus our Lord." Romans 8:38-39
Lastly, Deuteronomy 10:12-13 (which reminds me of Micah 6:8) says this about fearing God.
"And now, Israel, what does the LORD your God require of you, but to fear the LORD your God, to walk in all His ways and to love Him, to serve the LORD your God with all your heart and with all your soul and to keep the commandments of the LORD and His statutes which I command you today for your good?
Fearing the Lord is revering Him and His ways so much out of our love for Him that we hate evil, walk in His ways, love Him, serve Him, and keep His commandments.
Fearing the Lord is not being so afraid of His wrath and judgement that we obey Him out of cowardice. We must obey Him because we love Him and hate evil as much as He does.
