The fear of the Lord is his treasure. (Isaiah 33:6)
“The fear of the Lord is his treasure.” And, oh, what a treasure is this fear! Treasure in ancient times was generally hidden; it was concealed from the eye of man, hoarded up, and not brought out ostentatiously to view. Wealthy men of old hid the knowledge of their treasures, lest they should be robbed of them by the hand of violence.
So spiritually, the fear of the Lord is hidden in the heart, and lies deep in the soul; it is not spread out ostentatiously to view, but is buried out of sight in a man’s conscience. But though hidden from others, and sometimes even from ourselves, this “fear of the Lord” will act as circumstances draw it forth. There may be times and seasons when we seem almost hardened and conscience-seared; sin appears to have such power over us, and evil thoughts and desires so carry us away, that we cannot trace one atom of godly fear within; and the soul cries, “What will become of me! Where am I going now! What will come next on such a wretch as I feel myself to be!”
But place him in such circumstances, say, as befell Joseph, then he will find that the “fear of the Lord” is in him a fountain of life, a holy principle springing up in his soul. Thus, this fear, which is a part of the heavenly treasure, acts when most needed. And the more the life of God is felt in the soul, the more the fear of God flows forth as a fountain of life to depart from the snares of death. The more lively the grace of God is in the soul, the more lively will godly fear be in the heart; and the more the Spirit of God works with power in the conscience, the deeper will be the fear of God in the soul.
