“The fear of the LORD is the beginning of wisdom: and the knowledge of the holy is understanding.” Prov. 9:10
The whole Mosaic economy according to Matt. 22:37, 40 is fulfilled by the man who loves God, the prophets, their denunciation of sin, their call to right character, and all obeyed in answer to the impulse of the love of God. The new fear of God, which is the beginning of wisdom, is love of God. The old fear of God, which was the beginning of unutterable foolishness, was slavish fear, fear born of ignorance of Him, fear that made men hurry away, banish His Name, and refuse to meet Him. The new fear is not fear that He will hurt me, it is fear lest I should hurt Him, fear lest I cause sorrow to His heart, fear lest my sin would Him again. That is the fear that is the beginning of wisdom, and that is the fear of love.
“Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind…..On these two commandments hang all the law and the prophets.” Matt. 22:37, 40
