What is the fear of the Lord?
The fear of the Lord is reverent awe before God that leads to trust and obedience. It is not terror of a harsh master but the right response of creatures to a holy and loving Creator, and Scripture calls it the beginning of wisdom.
“Fear” sounds like an odd word to attach to a loving God. Yet the phrase “the fear of the Lord” runs through the whole Bible, and it does not mean what we first imagine. It describes a person who takes God seriously: who is amazed by who He is, trusts Him and wants to please Him.
Awe, not terror
The book of Proverbs opens its teaching with this thought.
The fear of the LORD is the beginning of knowledge: but fools despise wisdom and instruction.
Prov 1:7 · King James Version (1769)
The New Geneva Study Bible explains that this is not blind dread but reverent trembling before God, listening with respect to what He has revealed. Jamieson, Fausset and Brown describe it as reverent trust, love and obedience, and add that anyone who fears God will fear to sin, because he does not want to displease Him.
Albert Barnes pictures the fear of the finite before the Infinite, of the sinful before the Holy. He adds that this fear has no torment in it and fits together with a child’s love for a father. John Gill makes the same distinction: he calls it a filial fear rather than a slavish dread of punishment, a fear that grows out of knowing God’s forgiving love (Psalm 130:4).
So the fear of the Lord is not the opposite of trusting Him. Frightened people run away from what they fear; people who fear the Lord run toward Him. The same Bible that calls us to fear God also says that His mercy reaches those who fear Him (Psalm 103:11).
The beginning of wisdom
Three passages say almost the same thing, and the repetition is deliberate.
The fear of the LORD is the beginning of wisdom: and the knowledge of the holy is understanding.
Prov 9:10 · King James Version (1769)
The fear of the LORD is the beginning of wisdom: a good understanding have all they that do his commandments: his praise endureth forever.
Ps 111:10 · King James Version (1769)
Matthew Henry reads the proverb to mean that a person who does not fear God has not yet learned the first lesson; whatever else he knows, he is only at the starting line. John MacArthur explains that this reverence is the basis of all spiritual knowledge, and that a person cannot have true understanding of life until he is forgiven and honors God. John Wesley, on the psalm, calls it the only foundation of true wisdom.
The psalm goes on to say that those who do God’s commandments have good understanding. Lopukhin notes that true knowledge of God is not in the one who merely believes in Him in theory, but in the one who lives by His commandments. Fear, in other words, is not a mood. It shows itself in how we live.
