“Happy is the one who is never without fear, but one who is hard-hearted will fall into calamity.”
– Proverbs 28:14

The fear of the Lord is the beginning and the foundation of all true religion. Without a solemn awe and reverence of God there is no foothold for the more brilliant virtues. He whose soul does not worship will never live in holiness.

He is happy who feels a jealous fear of doing wrong. Holy fear looks not only before it leaps, but even before it moves. It is afraid of error, afraid of neglecting duty, afraid of committing sin. It fears ill company, loose talk, and questionable policy, This does not make a man wretched, but it brings him happiness. The watchful sentinel is happier than the soldier who sleeps at his post. He who foreseeth evil and escapes it is happier than he who walks carelessly on and is destroyed.

Fear of God is a quiet grace which leads a man along a choice road, of which it is written, “No lion shall be there, neither shall any ravenous beast go up thereon.” Fear of the very appearance of evil is a purifying principle which enables a man through the power of the Holy Spirit to keep his garments unspotted from the world. Solomon had tried both worldliness and holy fear: in the one he found vanity, in the other happiness. Let us not repeat his trial but abide by his verdict.
